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.

Description

A kind of compact blue light crystal component
Affiliated technical field
The invention belongs to laser technology field, particularly relate to a kind of design and preparation of compact blue light crystal component.
Background technology
Utilize the parts of the required assembling of inner cavity frequency-doubling generation blue laser device a lot of in the past, be difficult to realize microminaturization; Each parts has certain independence, regulating step between laser, nonlinear crystal, optical element and semiconductor laser diode is various, the production line that assembles whole laser is long, production efficiency is lower, whole laser structure complexity, the production cost height is not suitable for producing in enormous quantities, can not satisfy of the actual requirement of existing society, bigger use limitation is arranged the miniaturization of visible light solid state laser.
Summary of the invention
The present invention relates to a kind of design and preparation of compact blue light crystal component, it is the Nd that utilizes the Nd:YAG laser crystal 3+The 946nm fundamental wave of laser, obtain the blue laser of 473nm wave band by the BIBO frequency multiplication.This crystal assembly is by laser crystal Nd:YAG, nonlinear optical crystal BIBO, and the resonant cavity formation that is coated on two plane of crystal optical thin films compositions.This crystal modular structure is:
Optical thin film 1/ laser crystal 2/ nonlinear crystal 3/ optical thin film 4
Description of drawings:
Fig. 1 is this crystal modular structure schematic diagram
Optical thin film 1 is HR946nm﹠473nm, HT-1319nm/1064nm/808nm. Laser crystal 2 is neodymium doped yttrium aluminum pomegranates Stone (being called for short Nd:YAG), dimensions is 3mm * 3mm * 2mm. Nonlinear optical crystal 3 is bismuthtriborate (being called for short BIBO), Dimensions is 3mm * 3mm * 5mm. Optical thin film 4 is HR946nm, AR-473nm, HT-1319nm/1064nm/808nm.
The characteristics of this compact blue light crystal component are above-mentioned Nd:YAG laser crystal device, BIBO nonlinear crystal device Respectively be coated with specific optical thin film on one side, plated film is not fixed together in the mode of light-sensitive emulsion gummed on one side, and these two specific Optical thin film forms the laserresonator of " flat-flat " cavity configuration.
The present invention also relates to the preparation method of this compact blue light crystal component, i.e. the orientation of crystal, cutting, polishing, plating Bonding technique between film and crystal.
Below we enumerate the typical method of implementing this invention.
1. crystal modular structure design
The characteristics of this compact blue light crystal component are, Nd:YAG laser crystal device, BIBO nonlinear crystal device respectively are coated with specific optical thin film on one side, plated film is not fixed together in the mode of light-sensitive emulsion gummed on one side, and these two specific optical thin films are formed the laserresonator of " flat-flat " cavity configuration.
This crystal modular structure is:
Optical thin film 1/ laser crystal 2/ nonlinear crystal 3/ optical thin film 4
As shown in Figure 1.
The 1st, optical thin film, HR946nm﹠amp; 473nm, HT-1319nm/1064nm/808nm.The 2nd, laser crystal Nd-doped yttrium-aluminium-garnet (being called for short Nd:YAG), dimensions is 3mm * 3mm * 2mm.The 3rd, nonlinear optical crystal three bismuth boracic acid (being called for short BIBO), dimensions is 3mm * 3mm * 5mm.The 4th, optical thin film, HR946nm, AR-473nm, HT-1319nm/1064nm/808nm.
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
