Abstract
We passively Q-switched a Neodymium-Lanthanum-Scandium-Borate (Nd:LSB) microchip laser with an antiresonant Fabry-Perot saturable absorber (A-FPSA) and achieved single frequency, 180 ps pulses with 0.1 μJ pulse energy at a repetition rate of 110 kHz. Due to 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 up to 7 MHz.
