MgO:PPLN+Nd:YVO4 Micro-modules for 532nm Generations
● Compact and  mini-size only 2x2.2x0.5mm
● High performance of temperature range characteristics
● High cost performance ratio
The MgO:PPLN crystals and Nd:YVO4 crystals is attached together by optical contact technique, neither focusing lens or OC mirrors is needed, the size of the micro-module is only 2x2.2 x0.5mm. Several mW to several tens mW output power of 532nm green laser can be obtained by the microchips. It is compact, wide-temperature running and high performance to cost ratio. It can be made into the green laser pointer and laser modules for industrial and military applications.
