A laser weapon is a directed energy weapon that directly destroys or disables a target by using a directed laser beam. Laser weapons can be categorized into tactical laser weapons and strategic laser weapons depending on the purpose of the operation. Laser communication is a communication mode in which laser light is transmitted in an atmospheric space. The emission device for atmospheric laser communication mainly comprises a laser (light source), an optical modulator, an optical emission antenna (lens) and the like. The receiving device mainly comprises a light receiving antenna, a photoelectric detector and the like.

When the light mixing assembly is specifically arranged, the light mixing assembly comprises an optical fiber 50 and a vibration device 40, wherein the input end of the optical fiber 50 is connected with the light emitting surface of the triangular lens, so that light emitted by the light emitting surface of the triangular lens can enter the optical fiber 50 for transmission, and the vibration device 40 is used for driving the optical fiber 50 to vibrate, so that three-color light can be uniformly mixed.

When the trichromatic laser propagates in the curved section 51, the trichromatic laser can be mixed by multiple high-frequency reflection superposition in the channel of the optical fiber 50 by the coherence of the laser distribution in the optical fiber 50. For example, when the light source assembly includes the first, second and third light sources 10, 20, and 3, the red, green and blue lasers may be reflected multiple times within the curved section 51 to improve the laser mixing effect.

As an alternative, the curved section 51 is a wave-shaped curved section 51. Illustratively, the curved shape of the curved section 51 may be sinusoidal or other types of undulating curved sections 51, such as serpentine curved sections 51, although it should be understood that the curved sections 51 of embodiments of the present utility model may be selected from different types of curved sections 51 as desired, not limited to the examples described above.

With continued reference to fig. 1, additionally, a laser input device 60 and a laser output device 70 are included as fixing devices for fixing both ends of the optical fiber 50. The laser input device 60 is a fixing device, which is used for fixing the input end of the optical fiber 50.

Referring to fig. 1 and fig. 2 together, fig. 2 shows a schematic structural diagram of a vibration device 40 according to an embodiment of the present utility model. The vibration device 40 provided in the embodiment of the present utility model is located between the laser input device 60 and the laser output device 70, and is used for driving the bending section 51 to vibrate.

On the one hand, the laser is mixed by high-frequency reflection superposition for multiple times in the channel of the optical fiber 50 through the coherence of the laser distributed in the optical fiber 50, so that the uniformity of light spots is improved. On the other hand, the optical fiber 50 mounted in the air is vibrated at a high frequency by the vibration motor 422, and in the vibration, the distribution and reflection of photons are overlapped and reflected by each other a plurality of times and then the photons pass through the same path again in a short time, so that the coherence and superposition of laser light can be outputted more uniformly.

In an alternative, the number of vibration motors 422 is two, and the two vibration motors 422 are arranged on both sides of the vibration table 421. As shown in fig. 1 and 2, the number of the vibration motors 422 is two, and the two vibration motors 422 are arranged at both sides of the vibration table 421. In particular, the vibration motors 422 are respectively connected to the vibration platforms 421 to synchronously drive the vibration platforms 421 to vibrate. In a specific vibration, the two vibration motors 422 are respectively connected to a motor driving module, and the motor driving module can control the vibration frequency of the vibration motors 422 to adjust the vibration effect of the vibration motors 422 to drive the bending section 51.

The number of the elastic members 423 is two, and the two elastic members 423 are respectively connected to the two vibration motors 422 in a one-to-one correspondence manner. If the elastic member 423 is a compression spring, one end of the compression spring is fixedly connected to the vibration motor 422, and the other end is fixedly connected to the bottom plate of the housing 41. When the vibration motor 422 is operated, the elastic member 423 may be used to buffer the vibration motor 422 to reduce the influence of the vibration motor 422 on the housing 41.

The vibration motor 422 provided by the embodiment of the present utility model may be an ultrasonic motor. Of course, it should be understood that the vibration motor 422 provided by embodiments of the present utility model is not limited to an ultrasonic motor, and other devices for providing high frequency vibrations may be used. The examples are not listed in the embodiments of the present utility model.

In addition, when the optical fiber 50 and the vibration device 40 are used as the light mixing component, the optical fiber 50 can be used for separating the light source component from the lens component 80 at a longer distance, so that the light source component can be arranged in a safer place, and the optical fiber 50 can be bent at will when light rays are transmitted, so that the arrangement position of the light source component is more flexible.

In one embodiment, lens assembly 80 includes a plurality of convex lenses, wherein light rays exiting the output end of optical fiber 50 are collimated by the plurality of convex lenses. At the output end of the optical fiber 50, the mixed laser may have different angles when emitted, so that the laser is collimated by a plurality of convex lenses, and in specific collimation, the angle between the convex lenses can be adjusted to make the laser propagate in parallel straight lines after being emitted.
