High-power (0.9 W cw) diffraction-limited semiconductor laser based on a fiber Bragg grating external cavity

摘要

We have developed a high-power (>0.9 W cw ) diffraction-limited semiconductor laser based on a tapered semiconductor optical amplifier using a fiber Bragg grating tn an external cavity configuration. Frequency-selective feedback from the fiber grating is m jetted into the amplifier via direct butt coupling through a single mode fiber, resulting in a spectrally stable and narrow (<0.3 nm) high-power laser for solid-state laser pumping, laser remote sensing, and optical communications. # 1997 American Institute of Physics.
