The water-cooling pipeline is communicated with two ends of the laser fixing plate 50, and the extending direction of the water-cooling pipeline is parallel to the length direction of the laser fixing plate 50, so that liquid flowing through the water-cooling pipeline can dissipate heat of each laser 200 fixed on the laser fixing plate 50 in time.

The present application is not limited to this.

As will be briefly introduced below, the laser aging detection apparatus 100 according to the embodiment of the present disclosure may perform aging detection on multiple types of lasers 200, for example, in the embodiment of the present disclosure, the laser aging detection apparatus 100 may perform aging detection on a semiconductor laser. Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as the working substance. When the laser deterioration detecting apparatus 100 performs deterioration detection of the semiconductor laser, the power supply mechanism 20 further includes a high-power semiconductor laser driving power supply.

Of course, in other embodiments, the laser degradation detection apparatus 100 may also perform degradation detection on other lasers, such as a fiber laser.

Part of the lasers can be output through optical fibers, for example, a semiconductor laser is output through the optical fibers, and the semiconductor laser is optically coupled with the light receiving system through the optical fibers during detection. The applicant found that during the installation process, interference, winding and the like occur between the optical fibers due to the close arrangement of the laser 200, and therefore, in order to ensure that the optical fibers do not interfere with each other, optionally, the laser degradation detection apparatus further includes a partition 60, and the partition 60 is disposed between the laser 200 and the light receiving system 10. The spacer 60 serves to separate the optical fibers.

Referring to fig. 3, as an embodiment of a structure of the partition 60, the partition 60 includes a bottom plate 61 and a plurality of partitions 62 disposed on the bottom plate 61. The partitions 62 are arranged perpendicular to the base 61, and the channels formed before each two adjacent partitions 62 are used for placing the optical fibers. In the embodiment of the present application, the number of the partition plates 62 is nine, and the partition members 60 form eight partitioned passages for placing the optical fibers, thereby ensuring that the optical fibers do not interfere with each other. Of course, the number of the partition boards 62 on the partition 60 may be determined according to the actual situation, for example, in other embodiments, the number of the partition boards 62 may also be seven, and the corresponding partition 60 forms six separated channels; also, for example, the number of partitions 62 may be five, with the corresponding divider 60 defining four separate passages.

As another embodiment of the structure of the partition 60, the partition 60 includes a plurality of partitions, the partitions are perpendicular to the loading plate 42 of the rack 40, and the partitions are fixedly connected to the loading plate 42, the partitions may be fixed by screws, or a locking groove for locking the partitions may be provided on the loading plate 42, and the partition and the loading plate 42 are fixedly connected by any method, which is not limited in the present application. Similar to the above structure, the channel formed before each two adjacent partitions is used for placing the optical fiber.

Next, a light receiving system 10 provided in the embodiment of the present application will be described. The light receiving system 10 is used for collecting the laser light emitted by the plurality of lasers 200 and collecting the output power of the laser light.

Referring to fig. 4 and 5, fig. 4 is a structural diagram of the entire light receiving system 10, and fig. 5 is a structural schematic diagram of the first light receiving plate. The light collecting system 10 includes a light collecting plate 11, a first light collecting plate 12, and a second light collecting plate 13. The first light-collecting plate 12 includes a first surface 121 and a second surface 122 disposed vertically. The second light-collecting plate 13 includes a third surface 131. The first surface 121 of the first light-receiving plate 12 and the third surface 131 of the second light-receiving plate 13 are disposed opposite to each other, and the hemispherical groove 123 is disposed from the first surface 121 to the inside of the first light-receiving plate 12 and from the third surface 131 to the inside of the second light-receiving plate 13. The second surface 122 is provided with a light transmitting hole 124, the light transmitting hole 124 is communicated with the hemispherical groove 123 of the first light-receiving plate 12, and the lighting plate 11 is arranged on the second surface 122 of the first light-receiving plate 12.

When the first surface 121 of the first light-receiving plate 12 is attached to the third surface 131 of the second light-receiving plate 13, the hemispherical grooves 123 on the two light-receiving plates form a complete spherical groove. In the embodiment of the present application, the complete spherical slot inside the light receiving system 10 is used for collecting laser light, so as to avoid that the laser light is emitted randomly during the aging detection of the laser 200, which endangers the personal safety. It should be noted that the number of the hemispherical grooves 123 on the first light-receiving plate 12 or the second light-receiving plate 13 indicates the number of the lasers 200 that can be collected by the light-receiving system 10. Generally, the number of the hemispherical grooves 123 on the first light-absorbing plate 12 and the second light-absorbing plate 13 is equal. For example, in the embodiment of the present application, the number of the hemispherical grooves 123 on the first light-receiving plate 12 and the second light-receiving plate 13 is eight, so that eight complete spherical grooves are formed when the first surface 121 of the first light-receiving plate 12 is attached to the third surface 131 of the second light-receiving plate 13. At this time, the light receiving system 10 may be configured to collect the laser light emitted by the eight lasers 200, that is, each spherical groove collects the laser light emitted by one laser 200 correspondingly. Of course, in other embodiments, the number of the hemispherical grooves on the first light-collecting plate 12 and the second light-collecting plate 13 may be set according to actual requirements, for example, the number of the hemispherical grooves 123 on the first light-collecting plate 12 and the second light-collecting plate 13 may be four or six, and the present application is not limited thereto.

It is understood that the number of the light passing holes 124 also corresponds to the number of the hemispherical grooves 123 of the first light-absorbing plate 12, for example, if the number of the hemispherical grooves 123 of the first light-absorbing plate 12 is eight, the number of the light passing holes 124 is also eight, and each light passing hole 124 is communicated with one hemispherical groove 123. That is, if the number of the hemispherical grooves 123 of the first light-collecting plate 12 is six, the number of the light-passing holes 124 is also six.

In the actual detection process, the first surface 121 of the first light-receiving plate 12 and the third surface 131 of the second light-receiving plate 13 need to be attached to each other, so that the first light-receiving plate 12 and the second light-receiving plate 13 need to be fixedly connected. As a fixed connection manner, the first light-receiving plate 12 and the second light-receiving plate 13 may be fixedly connected by screws, for example, screw holes are provided on both the first light-receiving plate 12 and the second light-receiving plate 13, and the screws pass through the screw holes on the first light-receiving plate 12 and the screw holes on the second light-receiving plate 13, so that the first light-receiving plate 12 and the second light-receiving plate 13 are fixedly connected.

Optionally, the inner walls of the hemispherical grooves 123 of the first light-collecting plate 12 and the hemispherical grooves 123 of the second light-collecting plate 13 are further coated with a diffuse reflection coating, it should be explained that the diffuse reflection coating is composed of a base material, a diffuse reflection material, a high thermal conductive material and a filler, the diffuse reflection coating is coated on the inner wall of the hemispherical grooves 123, so that glare or light spots can be eliminated, good light color consistency is ensured, that is, light can be homogenized through the diffuse reflection coating, thus the proportion of light received by the light-collecting plates 11 is consistent, and the situation of inaccurate laser power monitoring caused by uneven light beams is avoided.

Referring to fig. 6, the lighting panel 11 optionally includes a circuit board 111 and a light detector 112. When the circuit board 111 is disposed on the second surface 122 of the first light-collecting plate 12, the light detector 112 is disposed in the light-passing hole 124. It is understood that the number of the light detectors 112 also corresponds to the number of the light passing holes 124, for example, if the number of the light passing holes 124 is eight, then the number of the light detectors 112 is also eight.

In the embodiment of the present application, the photo detector 112 is a PD photo detector. The circuit board 111 is a PD acquisition circuit board.

To explain the principle of the light receiving system 10, the laser 200 is optically coupled to the light receiving system 10 via an optical fiber. In the embodiment of the present application, the first light-receiving plate 12 includes a fourth surface 125, the fourth surface 125 of the first light-receiving plate is disposed opposite to the first surface 121 of the first light-receiving plate 12, and the fourth surface 125 of the first light-receiving plate 12 is disposed with a fiber inlet 126, and is connected to the optical fiber through the fiber inlet 126, so as to realize optical coupling between the laser 200 and the light-receiving system 10. The laser emitted by the laser 200 is output through the optical fiber and enters the light receiving system 10 from the optical fiber inlet hole 126 of the first light receiving plate 12, and the spherical groove inside the light receiving system 10 can collect the laser, so that the problem that the laser is randomly emitted to endanger the personal safety during the aging detection of the laser 200 is avoided. In addition, a diffuse reflection coating is applied to the spherical grooves, by which light can be homogenized. The homogenized laser light is detected by the light detector 112 through the light-transmitting hole 124, and finally the lighting panel 11 transmits the power of the detected laser light to the host 30.

With continued reference to fig. 5, optionally, in order to better fix the optical fibers, a fiber fixing block 127 is further disposed on the fourth surface 125 of the first light-collecting plate 12. The optical fiber fixing block 127 is provided with an insertion hole, and the ceramic ferrule on the optical fiber can be directly inserted into the insertion hole on the optical fiber fixing block 127.

In an actual test process of the laser 200, the output laser power is too high, which may cause the light receiving system 10 to generate heat and scald, and therefore, in the embodiment of the present application, in order to dissipate heat of the light receiving system 10 in time, the water cooling pipeline 128 is also disposed inside the light receiving system 10. Specifically, water cooling pipes 128 are provided inside the first light-absorbing plate 12 and the second light-absorbing plate 13. Taking the water cooling pipe 128 on the first light-absorbing plate 12 as an example, the water cooling pipe 128 on the first light-absorbing plate 12 is communicated with two ends of the first light-absorbing plate 12, and the extending direction of the water cooling pipe 128 is parallel to the length direction of the first light-absorbing plate 12, so that the liquid flowing through the water cooling pipe can timely dissipate heat of the first light-absorbing plate 12. In this embodiment, the number of the water cooling pipes inside the first light-collecting plate 12 is two, and in other embodiments, the number of the water cooling pipes may be one or four. Of course, in other embodiments, the water cooling pipe 128 may be curved for better heat dissipation. The present application is not limited to this.

It should be noted that, before the optical transceiver system 10 provided in the embodiment of the present application is actually used, calibration needs to be performed, first, a standard power meter is selected, so that the laser 200 measures an output power every 1A within a range of 1 to 12A (P1 to P12), then the laser 200 is optically coupled with the optical transceiver system 10, and the current of the laser 200 is continuously adjusted, so that the laser 200 measures a current value obtained by one daylighting panel 11 every 1A within a range of 1 to 12A (I1 to I12). In the actual aging detection process, when the current value acquired by the lighting panel 11 is I1, the corresponding actual output power is P1. Please refer to the following table for details.
