Abstract

A diode-pumped $Tm, Ho : KLu {({WO}_{4})}_{2}$ microchip laser passively $Q$ -switched with a Cr:ZnS saturable absorber generated an average output power of 131 mW at 2063.6 nm with a slope efficiency of 11% and a $Q$ -switching conversion efficiency of 58%. The pulse characteristics were $14 ns / 9 μJ$ at a pulse repetition frequency of 14.5 kHz. With higher modulation depth of the saturable absorber, $9 ns / 10.4 μJ / 8.2 kHz$ pulses were generated at 2061.1 nm, corresponding to a record peak power extracted from a passively $Q$ -switched Tm,Ho laser of 1.15 kW. A theoretical model is presented, predicting the pulse energy and duration. The simulations are in good agreement with the experimental results.
