Very high-power (425 mW) AlGaAs SQW-GRINSCH ridge laser with frequency-doubled output (41 mW at 428 nm)
- IBM Research Div., Zurich Research Lab., CH-8803 Rueschlikon (CH)
This paper demonstrates a very high-power AlGaAs single quantum well GRINSCH ridge laser operating in a diffraction-limited fundamental transverse mode up to 360 nW at a wavelength of 856 nm. The maximum power output of the laser reached 425 mW and was limited by thermal saturation of the device and not by catastrophic optical mirror damage. These lasers not only exhibit very high power levels, but also show excellent reliability at high output power levels. The extremely high, CW fundamental mode power combined with very low-intensity and optical low-phase distortion as well as low astigmatism render this ridge waveguide laser very suitable for optical storage systems, printers, and direct frequency doubling. These devices have been successfully used for direct frequency doubling of their output in a resonant KNbO{sub 3} cavity yielding 41 mW of blue radiation at 428 nm.
