We passively Q switched a monolithic Nd:YAG ring laser [monolithic isolated single-mode end-pumped ring laser (MISER)] using an evanescent-wave coupled antiresonant Fabry–Perot saturable absorber. Single-frequency, 0.7-μJ pulses with a pulse width below 100 ns at an ≈1-MHz repetition rate are demonstrated. Pulse width and repetition rate can be varied by changing the distance and thus the coupling strength between the crystal and the absorber.
