1.5 Watt passively Q-switched diode-pumped cw Nd:YAG laser

Abstract A medium-power all-solid-state diode-pumped cw Nd:YAG laser, passively Q -switched employing Cr 4+ :YAG as saturable absorber, has been developed. Optimum coupling operation at the 1064 nm working wavelength resulted in 100 μJ, 36 ns, nearly diffraction limited pulses at 15 kHz repetition frequency, with 1.5 W average power output. We discuss the characterisation of the passive Q -switching elements and the laser operation.
