Abstract: Pumped by a Ti:sapphire laser, a passively Q-switched laser oscillation from an unprocessed Nd:LaB3O6 cleavage microchip with a Cr4+:YAG saturable absorber has been demonstrated. The influence of the transmission of the output coupler on the pulse width and repetition rate at various absorbed pump powers has been investigated. A pulse with 2.8 μJ energy, 2.2 ns duration, and 29 kHz repetition rate at 1060 nm was obtained at the absorbed pump power of 1.25 W and output coupler transmission of 3.2%, which results in 1.25 kW peak power. The polarization and spectral properties of laser radiation were measured. [ABSTRACT FROM AUTHOR]
