Abstract

A tunable Er:YAG laser, side pumped by a quasi-cw InGaAs diode array, generates > 500 mW of power at 2.936 μm. 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-μm-thick YAG étalon. The tuning range is 2.933–2.939 μm. 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.
