We describe a continuous-wave optical parametric oscillator operated within a semiconductor disk laser, free of relaxation oscillations associated with neodymium-based systems. Parametric threshold occurred at 1.4 W primary (diode) pump power and 8.5 W yielded 205 mW idler.
We report on the epi-layer design and lasing characteristics of GaSb-based VECSELs emitting at 2.35mum optimized for resonant optical in-well pumping around 1.95mum. Compared to conventional barrier-pumped devices, the power conversion efficiency is significantly increased.
Pump power scaling with spot size is studied experimentally and theoretically in a 1060 nm VECSEL with a diamond heatspreader. The dependence of the efficiency and thermal roll-over on pump spot size are discussed.
We report high-performance single-frequency operation of a directly diode pumped GaSb vertical-external-cavity surface-emitting laser (VECSEL) at 2.3 mum. Tunability of >25 nm with a maximum single frequency output of 0.68 W is demonstrated.
We report the first high-power vertical external-cavity surface-emitting laser operating at 1.3 /spl mu/m. Continuous-wave output power greater than 0.6 W was achieved using a GaInNAs/GaAs structure capillary-bonded to a single-crystal diamond heatspreader.
