Paper Abstract

Longitudinally diode pumped monolith Nd:YAG laser operating at wavelength 1.34 μm Q-switched by V:YAG saturable absorber was designed. The monolith combine inside undoped YAG crystal, active YAG crystal doped with Nd3+ ions and YAG crystal doped with V3+ ions as saturable absorber. The pumping radiation is directed through the dichroic resonator mirror to the undoped YAG part which is diffusion bounded to the active Nd:YAG crystal. This configuration ensures the effective heat removal and lower thermal distortion of the active crystal part. V:YAG saturable absorber is diffusion bounded to the un-pumped face of the Nd:YAG section. Thanks to this configuration the effective heat removal from the saturable absorber is accomplished, number of reflecting surfaces and also complete resonator length are reduced. It was proved that this compact monolith system is more stabile, efficient and easy to operate in comparison with classical separated laser configuration.
