Optimally, crystal cartridge is fixed on the pumping source support by sucker.
Optimally, sucker and pumping source support are set to one.
The technical scheme of laser crystal assembly method of the present invention is such: it comprises the following steps:
A, pumping source is assembled in the pumping source support;
B, the position of proofreading and correct target make target in the light path of pumping source;
C, adjust negative pressure intensity;
D, crystal is put into the center of sucker;
E, open pumping source, make ray cast to target;
F, slight translation or rotation crystal, and observe crystal bright dipping situation, judge crystal mass according to the bright dipping situation, select defective crystal;
G, put into crystal cartridge and contact gently with qualified crystal;
H, crystal and crystal cartridge are fixed together.
Perhaps step G is arranged on after the step D, by the position of adjusting crystal cartridge the position of crystal is adjusted.
It comprises support, target the crystal assembling device of the technical program, support comprises pumping source support, crystal cartridge, crystal cartridge is arranged on the pumping source support near an end of target and is positioned on the light path of pumping source, the pumping source support is used for fixing laser pumping source, laser beam is fallen on the target, and the position of pumping source can go out optical position according to best crystal and adjusts like this.Immobilize behind the target calibration accuracy, carry out crystal adjustment and judgement by facula position and intensity that laser is mapped on the target.
On the technical program pumping source support, the negative-pressure adsorption hole is set in the support of laser pumping source and crystal cartridge, the fixture of crystal cartridge is set to sucker, guarantee the coplanarity of two part bottom surfaces of crystal and crystal cartridge by the mode of negative-pressure adsorption, and online crystal test is arranged, the axiality of the crystal that can guarantee to take on is good.
The technical program sucker and pumping source support are set to one.
The technical program integral body is fixed on the stabilized platform.
The assembly method introducing pumping source of the technical program carries out on-line testing and rejects bad crystal, greatly improves the yield that assembles out crystal, has improved on the whole the fabrication yield of laser, makes efficient, is fit to batch production.
The technical program also can be put into first crystal cartridge as required, puts crystal again, by support crystal is carried out the position adjustment.Sucker also can be made of one with the pumping source support as required.
