Paper Abstract

We report the development of a high-power Er:strengthened- glass laser emitting at the eye-safe 1.535 μm wavelength. The flashlamp pumped Cr:Yb:Er:glass produced 330 mJ output @ 0.45% slope efficiency. Thermo-optical measurements indicated strong thermal lensing, of 16 diopter/kW and mild birefringence induced depolarization of 5% at 200 W. In terms of radial and birefringence elastooptical coefficients these data determine the values of 0.075 ± 0.002 and 0.0094, respectively. For a hemispherical resonator configuration a TEM00 beam was achieved.
