Diode-pumped passively Q-switched self-frequency-doubling Nd : YAB laser

摘要

We report on a diode-pumped 531-nm self-frequency-doubling Nd:YAB laser passively Q switched by a Cr4+:YAG saturable absorber. Pumped by 1.4 W of 807-nm GaAlAs diode laser radiation, the Nd:YAB laser system generates 5.6-ns-long TEM00 light pulses with an energy of 1.0 mu J at a repetition rate of 45 kHz. The experimental data are compared with the results of a numerical analysis based on rate equations that consider the optical properties of the Nd:YAB crystal and of the Cr4+:YAG saturable absorber.
