Title: 1-W average power levels and tunability from a diode-pumped 2. 94-[mu]m[integral] Er:YAG oscillator

Abstract

A tunable Er:YAG laser, side pumped by a quasi-cw InGaAs diode array, generates [gt] 500 mW of power at 2.936 [mu]m. The cavity is a 4-cm plano-concave resonator that uses total internal reflection on the pump face of the Er:YAG crystal to couple the diode emission into the resonating modes of the oscillator. Tuning is accomplished by angle tuning a 300-[mu]m-thick YAG etalon. The tuning range is 2.933--2.939 [mu]m. Thermal lensing limits the duty factor to 4% or 8%, depending on the Er:YAG crystal thickness (2 or 1 mm). A 2.5-cm-long resonator operates at an 11% duty factor and generates 1.3 W of average power.
