Abstract

A passively Q-switched 1.06 μm Nd:GdVO ₄ laser with a [100]-cut Cr ⁴⁺:YAG saturable absorber was demonstrated. The output characteristics were investigated when the anisotropic transmission of Cr ⁴⁺:YAG crystal and the incident pump power level were considered. The experimental results showed that it was feasible to generate laser with narrower pulse width (τ _p), higher pulse energy and peak power when the polarization direction of laser was parallel to the [001], [010], [001], and [01̄0] orientations of the Cr ⁴⁺:YAG crystal. The different changes of τ _p as a function of incident pump power was observed due to the anisotropy of transmission of Cr ⁴⁺:YAG and the different gain levels (pump power levels). If the Cr ⁴⁺:YAG was fully bleached as a result of high cavity gain or due to the laser polarization direction was parallel to the [001], [010], [001̄], and [01̄0] orientations, τ _p was constant, otherwise τ _p decreased when the gain increased.
