Example Embodiment

[0038] The present invention is a method for fixing a resonant cavity mirror to deal with potential detuning, see image 3 As shown, the steps are as follows:

[0039] Step 1: Fix the tooling matched with the laser on the optical platform with screws; fix the laser casing (such as figure 2 As shown in middle 9) fix it on the tooling with screws; fix the lens holder (such as figure 1 As shown), fix the corresponding position of the laser with screws with flat and elastic washers; set the cavity mirror (such as figure 2 Shown in 6) Use a mechanical adjustment frame to clamp, adjust the position of the cavity mirror to match the shape of the lens holder, record the height displayed on the height adjuster on the adjustment frame at this time, and then properly raise the height to set aside the adjustment angle space. Then use the adjusting frame to adjust the angle of the lens to make the laser output laser. At this time, the laser is in the state of the cavity mirror (such as fi...

Abstract

The invention provides a resonant endoscopy fixing method. The resonant endoscopy fixing method comprises the following steps of 1, fixing a laser and a lens seat, and pasting the endoscopy; 2, marking a pointing direction of a normal line of the endoscopy, and waiting glue to be cured; 3, comparing pointing directions of the normal line of the endoscopy to obtain a deflection direction and deflection degree if the endoscopy rotates after the glue is completely cured; 4, fabricating two foils with different thicknesses, and respectively padding the two foils under a front arm and a rear arm ofthe lens seat to change a pitching angle of the endoscopy; 5, rotating the lens seat to adjust a directional angle; 6, tightening a screw so that the marks in a normal line direction of the endoscopyare coincided, and repeating the step 4 and the step 5 if the marks cannot be coincided; and 7, maintaining by adjusting the lens seat when the endoscopy is mistuned after the laser is used for a long time. By the steps, the laser can be rapidly maintained when encountered with the problem that the endoscopy is mistuned, meanwhile, favorable long-term stability, the temperature stability and shock resistance also can be ensured, and the problem that the efficiency and the accuracy cannot be compatible during the assembly and maintenance process of the laser.

Description

technology field. [0001] The invention provides a method for fixing a resonant cavity mirror to deal with the possibility of potential detuning, relates to a method for fixing a resonant cavity mirror during laser design, and belongs to the field of information technology. Background technique [0002] Since the laser has extremely high requirements on the normal pointing accuracy of the cavity mirror, the fixing method of the cavity mirror must be carefully considered in the assembly and subsequent maintenance links when designing the laser to ensure its high operability and stability. sex. Among the existing fixing methods, large lasers are mostly fixed by adjustable mirror frames. This method has very good maintainability, but takes up a lot of space, and has poor long-term stability, temperature stability and shock resistance. Lasers with a relatively compact structure often use a fixed mirror base, and the method of bonding the cavity mirror to it at one time. The lo...
