An embodiment of the present application discloses a control system for a laser. The following describes the technical solution of the present application by using specific embodiments. The control system of the laser involved in the specific implementation is only a preferred embodiment, and not all possible applications of the present application. An embodiment. The control system of the laser to which the various embodiments of the present application are based is based on a fiber laser.

Referring to FIG. 1, a schematic diagram of a control system of a laser in an embodiment of the present application. As illustrated in FIG. 1, the control system of the laser includes: a first-level optical path control module 1 configured to control a primary optical path operating current of a primary pump source, and configured to configure the primary optical path operating current.

The control system of the laser in the above embodiment includes the first-stage optical path control module 1, the first-stage optical path configuration module 2, the secondary optical path control module 3, the secondary optical path configuration module 4, and the processing module. 5. The primary optical path operating current of the primary pump source can be configured by the primary optical path configuration module 2 and the processing module 5, and the primary optical path is sent to the primary optical path control module 1 through the processing module 5 The current control signal causes the primary pump source of the laser to operate in accordance with the configured primary light path operating current. The full working current of the secondary pump source controlled by the secondary optical path control module 3 is configured by the processing module 5 and the secondary optical path configuration module 4, and is controlled by the secondary optical path control module 3 The secondary optical path operating current of the stage pump source. The control system of the laser in the above embodiment can be set not only to control the primary optical path working current and the secondary optical path working current, but also can be configured to configure the primary optical path operating current of the primary pump source and the full amount of the secondary pump source. Working current. The control system control of the laser is simpler than the control system of the prior art, and the complicated control process of the laser is realized in a relatively economical manner.

Because of the difference between the fiber used by the laser and the laser laser, the primary optical path operating current of each primary laser needs to be configured is different. In the embodiment of the present application, the primary optical path operating current of the primary pump source may be disposed within a certain range and is composed of a set of current values. For example, the primary light path operating current of the primary pump source ranges from 2A to 4A, and the 2A~4A can be divided into 12 parts. The current values corresponding to all the equal points constitute one set of the primary pump source. The stage optical path operates current, and the primary optical path operating current of the set of primary pump sources can be solidified to the processing module 5 for configuration by the primary optical path configuration module 2.

The processing module 50 and the detecting module 60. The primary optical path control module 10, the primary optical path configuration module 20, the secondary optical path control module 30, the secondary optical path configuration module 40, and the processing module 50 are the same as the laser illustrated in FIG. The function of the control system is the same, and the detecting module 60 is arranged to detect the temperature inside the laser and the light-emitting condition of the laser. The processing module 50 controls the primary optical path control module 10 and the second when the detecting module 60 detects that the temperature inside the laser is higher than the first temperature threshold or the temperature inside the laser is lower than the second temperature threshold. The stage optical path control module 30 cuts off the power supply of the laser; when the detection module 60 detects that the temperature inside the laser falls below a third temperature threshold or the temperature inside the laser rises above a fourth temperature threshold, the processing module The first stage optical path control module 10 and the second optical path control module 30 are controlled to restore the power supply of the laser; the first temperature threshold>the third temperature threshold>the fourth temperature threshold>the second temperature threshold. For example, the first temperature threshold is 60 ° C, the second temperature threshold is 5 ° C, the third temperature threshold is 55 ° C, and the fourth temperature threshold is 10 ° C. The first temperature threshold and the third temperature threshold are 5 ° C apart, and the second temperature threshold and the fourth temperature threshold are 5 ° C apart, which is beneficial to prevent the laser from changing inside the laser. Close and open frequently.

In a state where the laser is not working, the detecting module 60 detects the duration of the accumulated laser light when there is a laser in the optical path of the laser, and the processing module 50 sends an alarm signal when the duration of the laser exceeds the first time threshold. Alarming, when the duration of the laser does not exceed the first time threshold, the accumulated duration of the laser is cleared; in the state where the laser is working, the detecting module 60 is in the optical path of the laser not detected. When there is a laser, there is no duration of the laser in the cumulative optical path. When the duration of the non-laser duration exceeds the second time threshold, the processing module 50 sends an alarm signal to alarm, when the duration of the absence of the laser does not exceed the second time. At the threshold, the accumulated duration of the absence of the laser is cleared.

In a possible implementation manner of the present application, the processing module 50 outputs a maximum current operation signal, and the secondary optical path configuration module 40 adjusts the maximum current operation signal to change the actual work corresponding to the maximum current operation signal. The current causes the secondary optical path control module 30 to control the secondary pump source to operate at a full operating current. Through the above process, the processing module 50 and the secondary optical path configuration module 40 jointly configure the full working current of the secondary pump source controlled by the secondary optical path control module 30.

In a possible implementation manner of the present application, the processing module 50 is connected to the host computer in a circuit or communication manner, and the processing module 50 changes the maximum when receiving the power signal sent by the upper computer.

Since the assignment of the maximum current operating signal has a one-to-one correspondence with the actual operating current of the secondary pump source, the actual operating current of the secondary pump source will also change when the assignment of the maximum current operating signal changes. For example, when the laser power output by the secondary pump source corresponding to the power signal is 50% of the maximum laser power output, the actual operation of the secondary pump source can be changed by changing the assignment of the maximum current working signal. The current, in turn, changes the laser power output by the laser to 50% of the maximum laser power.

To detect the light output of the laser. The detecting unit 603 is arranged to detect an operating current of the laser. In a state where the laser is not working, when the detecting unit 603 detects that the operating current is greater than the first working current threshold, the processing module 50 sends an alarm signal to alarm; in the state where the laser is working, when the detecting unit The processing module 50 sends an alarm signal to report an alarm when the operating current is greater than the second working power threshold. The second operating current value is greater than the full operating current.
