Abstract

Use of a V3+:Y3Al5O12 crystal as a saturable absorber Q-switch for 1.07 and 1.35μm Nd:KGd(WO4)2 diode pumped lasers shows a considerable dependence of output characteristics on the orientation of the intracavity field polarization vector regarding V3+:Y3Al5O12 crystallographic axes. Anisotropy of nonlinear absorption of V3+ ions in a Y 3Al5O12 single crystal at wavelengths of 1.08 and 1.35μm has been experimentally studied. The experimental data are analyzed within the framework of a phenomenological model when the V3+ ions are described as three sets of linear dipoles oriented along the crystallographic axes. Ground-state and excited-state absorption cross sections at 1.08 and 1.35μm are evaluated to be σgsa=3.4×1018cm2, σesa=3.0×1019cm2 and σgsa=5.4×1018cm2, σesa=4.8×1019cm2, respectively. Saturation fluence and intensity at 1.08 and 1.35μm are estimated as 55mJ/cm2 and 1.1MW/cm2, respectively.
