Abstract:
The saturation of the optical absorption in V3+ : YAG crystal is investigated. The absorption cross section of tetrahedral V3+ at 1.08 μm is estimated to be 8.2±2.5x10-18 cm2. Q-switching and passive mode-locking for a number of solid state lasers with wavelengths at 747 nm, 780 nm, 1.06 μm and 1.34 μm have been obtained with a V3+ :YAG saturable absorber.
