Nd:KGW crystal is a kind of laser crystal that can realize high concentration doping.Because the crystal can be mixed with high concentrations of Nd ions and has a large emission area, its monopulse and low-repeat laser performance is better than Nd: YAG. The absorption band of Nd: KGW crystal is at 808 nm, which can effectively couple with LD pump source (emitting wavelength is 808 nm) to improve its luminous efficiency. Moreover, its half height and width of 12 nm makes it able to accommodate the drift of LD emission wavelength with temperature, which is conducive to conducting diode pumped KGw laser experiment and device research. Nd:KGW can not only realize free oscillation, Q switching, mode locking operation, but also realize Raman conversion.
