We passively Q switched a Nd:LaSc(3)(BO(3))(4) microchip laser with an antiresonant Fabry-Perot saturable absorber (A-FPSA) and achieved single-frequency, 180-ps pulses with 0.1 microJ of pulse energy at a repetition rate of 110 kHz. Because of the compactness and scaling possibilities offered by the A-FPSA, the pulse width can be varied from 180 ps to 30 ns and the repetition rate from 50 kHz to 7 MHz.
