一、激光打孔机原理、参数及工艺要求我厂激光打孔机是宝石打孔的专用设备,是以钕玻璃为工作物质的固体激光器。工作频率为每秒50~70次,完成一个打孔需1~2次脉冲,脉冲宽度在0.5~2毫秒,输出能量为1~2焦耳。为了获得不同能量和不同激光束进行有效打孔光学谐振腔在一定的要求范围内(选择),打小孔粒子的腔长800毫米,打大孔粒子的腔长520毫米,构成谐振腔的两个反射镜,1.06微米波长,透射率为50%、95%的平面反射镜分别为φ20毫米,聚光器采用椭圆柱形聚光器,为了使工作物质吸收光谱及脉冲氙灯发光,光谱相匹配,聚光器采用银板反射镜镀层,工作时谐振腔聚光器用冷水冷却,聚光器长度:170mm、长轴720mm、短轴6.2mm,
First, the principle of laser drilling machine, parameters and process requirements I plant laser drilling machine is a gem drilling special equipment, is based on the work of neodymium glass solid material laser. The working frequency is 50 ~ 70 times per second. It takes 1 ~ 2 pulses to finish a punch, the pulse width is 0.5 ~ 2ms, and the output energy is 1 ~ 2 Joules. In order to obtain different energy and different laser beams for effective perforating optical resonator within a certain range of requirements (choice), hit the hole length of 800 mm particles, hit the cavity length of 520 mm hole particles constitute the resonant cavity A mirror, 1.06 micron wavelength, the transmittance of 50%, 95% of the plane mirrors were φ20 mm, the condenser using elliptical cylindrical concentrator, in order to make the working substance absorption spectrum and pulsed xenon lamp luminescence, matching the spectrum , Concentrator silver plate mirror coating, working cavity resonator condenser with cold water cooling, condenser length: 170mm, long axis 720mm, short axis 6.2mm,
