MgO:PPLN+Nd:YAG modules for 561nm Laser Generations
● Small and compact in size
● Alignment free
● Easy to be integrated into laser systems
MgO doped periodically poled lithium niobate Crystal chips (MgO:PPLN crystals) is used as the frequency conversion element, it converts 1123nm laser to 561nm laser, the 1123nm laser is generated from Nd:YAG crystals pumped by 808nm LD, the PPLN crystals and Nd:YVO4 crystals is bonded on a silicon substrate, then the whole component is wrapped by the copper heat-sink.
