Abstract
The invention relates to a compact-type blue-light crystal assembly design and fabrication. The blue-light crystal assembly can obtain 473-nm blue laser beams from 946-nm Nd<3+> fundamental laser beam generated by a Nd:YAG laser crystal by frequency multiplication using BIBO. The crystal assembly consists of the laser crystal Nd:YAG, a nonlinear optical crystal BIBO, and a resonant cavity formed by optical films coated on the surfaces of the two crystals. The compact-type blue-light crystal assembly has a modular structure of optical film (1)/laser crystal (2)/nonlinear crystal (3)/optical film (4). The crystal assembly is characterized in that specific optical films are coated on one side of the Nd:YAG laser crystal and the BIBO nonlinear crystal, and the non-coated sides are fixed together through photoresist, so that the two specific optical films form the laser resonant cavity with a 'flat-flat' structure.

2. crystal module preparation
Step 1 quartz crystal device preparation: the orientation, cutting, polishing and the plated film that comprise Nd:YAG, BIBO crystal
Step 2 gummed is prepared: long-staple cotton dips in the cemented surface of alcohol wipe crystal, places in the dust shield case stand-by after the wiped clean.
Step 3 is used the cemented surface of BIBO crystal horizontal positioned up quantitatively to get reagent needles, extracts a certain amount of light-sensitive emulsion, drops in crystal cemented surface middle position.
Step 4 is taken out the YAG crystal that pairing is used, and cemented surface is slowly closed from another angle of an angle, and observe under incandescent lamp, if find to have bubble in the glue-line, need open two crystal, and the cemented surface of wiping crystal drips glue again and glues together again.
Step 5 is utilized the level correction instrument, by overstocking of probe, adjusts to the plated film face assurance level (deviation＜0.1 degree) of two crystal;
Step 6 utilizes ultraviolet etc. from crystal on side face irradiation gummed part, solidifies 1min.
Crystal module after the step 7 pair curing carries out frictioning, cleans.
Step 8 is measured the laser transformation efficiency of crystal module
