Embodiment Construction
[0017] Attached below Figure 1 ~ Figure 3 , to describe this embodiment in detail.
[0018] The technical scheme adopted in the present invention is as follows. The design method of the reflective surface of the high-power solid-state laser in the present invention is specifically: firstly, according to the size of the working substance 7, the pump lamp 4, the ultraviolet filter glass tube 6 used, and the minimum size of the processing device for clamping these components, Determining the distance between the two foci of the single ellipse in the double ellipse is 2 times the focal length of the ellipse (that is, the following parameters are determined: the radius of the pump lamp 4, the distance (1-2mm) between the pump lamp 4 and the inner wall of the glass tube 6, the glass The thickness of the tube 6 (1-1.5mm), the outer diameter of the glass tube 6 covering the working substance 7 (by the diameter of the working substance and its distance from the inner wall of the glas...

The invention relates to a method for designing the reflective surface of pump light of large-power solid laser and a relative device, wherein said reflective surface comprises ellipse arc reflective surface (1) and arc reflective surface (2); and the method comprises: first using general method to design the ellipse reflective surface; then using the light track method to fix the position of working material; then fixing the cross point between the ellipse arc reflective surface and the arc reflective surface; making the vertical line of main axle at the center of working material, while said line has two cross points with the ellipse reflective surface, and two sections of ellipse arcs between the cross points and the critical pint are the needed ellipse arc reflective surface; using the center of pump light as round center, using two critical points as arc ends to make arc, to obtain the arc reflective surface; using the straight line AB through the center of working line and vertical to the main axle as symmetry line to draw another half sound to obtain the whole pump chamber reflective surface. With said invention, the pump effect is better, and the output power and light quality of laser can be improved.
Description
technical field [0001] The invention relates to a design method and device for a reflection surface of pumping light of a high-power solid-state laser, belonging to the technical field of lasers. Background technique [0002] The reflection surface of the pump light of the solid-state laser is the coupling surface of the laser. Its function is to reflect the light emitted by the pump source, that is, the pump lamp, to the laser working material (laser crystal), which plays a role in the power and beam quality of the laser. decisive role. [0003] At present, high-power specular reflective metal cavity lasers generally use double lamps to pump a single laser crystal, and its reflection cross-section is a pure ellipse. The straight line where the three points are located is the direction of the major axis of the double ellipse, and the direction perpendicular to the major axis is the direction of the minor axis. High-power solid-state lasers using this traditional reflective...
