Abstract :
A tapered laser emitting near 1.8 μm wavelength is configured into a simple external cavity, and emits up to 1.44 W under quasi-CW operation, of which 620 mW is in a near-diffraction-limited pattern. Further improvement, including extension to CW operation, is expected in these devices, and may open new application areas for mid-infra-red high-power diffraction-limited laser diodes
