Embodiment 1

[0025] This embodiment includes a laser module array. The laser module array includes at least two laser modules 1 with different temperature bandwidths. The laser beam emitted by the laser module array is shaped by a beam shaping system and an afocal optical system to form a beam Combined beam. The afocal optical system is composed of two parabolic mirrors, one large and one small. The larger one is a concave parabolic mirror 4 with a circular hole in the center to transmit light. The diameter of the circular hole is slightly larger than the diameter of the output light; the smaller one is convex parabolic. Mirror 5, the two parabolic mirrors are confocal. The beam shaping system is arranged in front of or behind the afocal optical system. The beam shaping system is set as a Galileo telescope lens group. The beam shaping system is set as a lens group consisting of a self-focusing lens and a spherical mirror. The laser modules in the laser module array are evenly arranged al...

Embodiment 2

[0028] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the light from the laser module array of this embodiment first passes through the afocal optical system to form a combined beam, and then passes through the beam expander lens 2 and the collimator lens 3 for shaping and output.

Embodiment 3

[0030] Such as image 3 , 4 As shown, the difference between this embodiment and Embodiment 2 is that the laser module array of this embodiment is provided with four laser modules.

Abstract

The invention relates to the field of laser application, in particular to an array type wide-temperature laser module capable of adjusting the laser power and the stability. The array type wide-temperature laser module is characterized in that by combined application of a plurality of laser modules 1, a beam shaping lens groups are added into different positions, so that the power and the stability of the wide-temperature laser module under the extreme temperature are improved, the temperature width of the module is improved in a disguised manner, and simultaneously the noise frequency of the output beam is improved; and when the array type wide-temperature laser module is used on specific equipment and instruments, the perception of the visual system of a person for the problems of fluctuation and line breaking and the like caused by the laser noise is not sensitive. The array type wide-temperature laser module comprises a laser module array, wherein the laser module array at least comprises two laser modules with different temperature bandwidth; and laser beams emitted by the laser module array form a bundle of synthetic beam after being shaped by a beam shaping system and an afocal optical system.

Description

[0001] Technical field [0002] The invention relates to the field of laser applications, and specifically refers to an array type wide temperature laser module capable of adjusting laser power and stability. [0003] Background technique [0004] With the continuous development of science and technology, the application range of wide-temperature laser modules is increasing, and the demand for wide-temperature laser modules with wide temperature and high stability is increasing. However, the laser modules currently on the market can only work normally within a narrow temperature bandwidth. When the ambient temperature is too high or too low, the laser will be too low and unstable. Summary of the invention [0005] In view of the above-mentioned defects, the present invention provides an array type wide-temperature laser module. Through the combined application of multiple laser modules 1, beam shaping lens groups are added at different positions to improve the wide-temperature laser...
