Abstract

We demonstrate the performance of a Nd: YAG laser, passively Q-switched with a Cr 4+ : YAG plate, which plays the double role of a passive Q-switch and a Brewster plate. The Brewster plate configuration contributes an intracavity loss of approximately 3.2 × 10-3 cm-1 along the cavity length. Losses contributed by the active Cr4+ ions in the plate relate to their excited state absorption. A freshly measured transmission saturation curve of Cr4+ : YAG suggests a ground state absorption cross section σgs = (8.7 ± 0.8) × 10-19 cm2, and an excited state absorption cross section σes = (2.2 ± 0.2) × 10-19 cm2 of the Cr4+ ions at λ = 1064 nm.
