Abstract

We have numerically investigated, for the first time, the optical performance and characteristics of diode-end-pumped passively Cr\(^{4+}\):YSO Q-switched solid-state Cr\(^{3 + }\):LiSAF lasers using a rate equation system extended to multi-wavelength. Homogeneously broadened emission spectra of the laser crystal and broad absorption spectra of Cr\(^{4+}\):YSO saturable absorber have been respected in the investigation. A tunable passively Q-switched laser operation is also developed with a birefringent filter plate used as an intracavity selective element. As a result, improved understanding of passively Q-switched Cr\(^{4+}\):YSO solid-state Cr\(^{3+}\):LiSAF lasers has been obtained in broadband and tunable laser operations. Characteristics of the tunable passively Q-switched Cr\(^{3 + }\):LiSAF laser were demonstrated to be clearly dependent on wavelength. The spectro-temporal evolution of a single pulse emitted from the passively Q-switched Cr\(^{3 + }\):LiSAF laser has been reported.
