0.7 W in singlemode fibre from 1.48 /spl mu/m semiconductor unstable-cavity laser with low-confinement asymmetric epilayer structure
2000
Applied to 1.48 /spl mu/m high-power unstable-cavity lasers, the concept of low modal gain is demonstrated to efficiently repel filamentation effects, enabling more than 700 mW to be coupled in a singlemode fibre from a single semiconductor laser diode.
