Paper Abstract
We report a mode-locked Vertical-External-Cavity Surface-Emitting Laser (VECSEL) that exhibits 13.7 nm of tuning
around a centre wavelength of 1042 nm. The wavelength tuning is achieved by incorporating an uncoated, 25 μm thick,
fused silica etalon into the cavity of the laser at Brewster's angle. The etalon is then tilted with respect to the cavity axis.
The etalon has a calculated free spectral range of 14 nm at normal incidence. The repetition rate of the laser is measured
to be 1.88 GHz. The pulse duration, averaged over the tuning range, is 1.9 ps corresponding to a mean time bandwidth
product of 0.46. For a sech2 pulse this is 1.46 times larger than the transform limit. The average power of the laser does
not fall below 2.6 mW and, over the tuning range, averages 3.5 mW. With appropriate amplification, such a laser would
be highly suited to the generation of heralded single photons in photonic crystal fibre.
