A review of the Techlasers Infiniti II 95mW 532nm Green Laser Pointer has been posted over at the GearDiary.
'The TechLasers high-powered green laser pointer puts out a nominal 95mW beam of 532nm light, which happens to be in the green region of the wavelength spectrum. Interestingly, the problems with direct generation of green light seems to dot my work history, so I was interested to find out how they were achieving the wavelength. Turns out they are using a 808nm infrared laser diode to pump (i.e. provide exciting energy to initiate the lasing process) a Nd:YVO4 crystal which emits 1064nm light. That light goes through a special crystal which is called a frequency doubler, which converts a significant portion of the input energy to 532nm light (for those following along at home, 532 is half of 1064, it really is that simple).'
