Description
Nd: YAG one of the mature developed laser crystals which is obtained by doping Nd ion into YAG crystal. The absorption bandwidth of Nd:YAG laser crystal are 730-760 nm and 790-820 nm, and usually pumped by flashtube or laser diode. The typical laser emission peak is 1064 nm, the wavelength of 946 nm, 1120 nm, 1320 nm and 1440 nm lasers can be emitted too through some measures, Q-switch and lock mode are adapted to obtain laser with different wavelength (532 nm, 266 nm, 213 nm etc.) and pulse width (10-25 ns) respectively, which makes the huge application in biophysics, medicine, military, machine, scientific research and architecture etc.. Commonly, the high concentration doped crystal is applied into pulse laser and the low concentration doped one is usually used in continuous wave output.
