High Power (>1 W) Semiconductor Lasers

Abstract

Coherent semiconductor sources based on flared amplifiers — monolithic and discrete MOPAs and flared unstable resonators have demonstrated the highest cw diffraction-limited output powers from semiconductor sources at wavelengths from 630 nm to beyond 2 μm. This talk will describe continuing advances in flared amplifier devices, including visible output powers approaching 1 W cw diffraction limited, powers up to 10 W diffraction-limited from monolithic devices, high-speed modulation, and more.
