A diode-side-pumped ZnSe:Cr{sup 2+} laser was operated with a 75 - Watt peak power 1.65 {micro}m InGaAsP/InP pump array. The laser was configured with a ``single-bounce`` architecture to maximize its round-trip gain. Peak output powers of {approx}0.3 Watt were obtained with a 10% - transmitting output coupler and a lightly-doped crystal. The estimated ``mode fill`` of {approx}0.06 will increase with Cr{sup 2+} concentration, raising the output power and extraction efficiency. With a grating tuner and MgF{sub 2}:Co{sup 2+} laser pumping, the laser tuned throughout the 2134 - 2799 nm range.
