Femtosecond synchronously in-well pumped vertical-external-cavity surface-emitting laser

Abstract: Abstract:We demonstrate the first synchronously in-well pumped verticalexternal-cavity surface-emitting laser (VECSEL). Depending on the cavity mismatch, laser pulses with a duration from 1 ps to 7 ps at a repetition rate of 76 MHz were generated directly from the laser at 860 nm. The application of extra-cavity pulse compression further shortened the pulse to a duration of 210 fs providing a peak power of 226 W.

“…Excellent results have been obtained lately in ultrashort pulse generation [44,45], as well as in generation of pulses with high average output power [46,47] and high repetition rate [48]. The spectral coverage of mode-locked [49] SDLs has also extended [50][51][52][53] Figure 3 gives an overview of maximum output powers achieved as a function of wavelength for both continuouswave (CW) and mode-locking operation regimes. It also provides a correspondence to main classes of material systems used to reach a certain wavelength region.…”

“…To date, mode-locked VECSELs have been demonstrated in various configurations that include high harmonic mode locking with > 100 GHz repetition rates using coupled cavities [358][359][360], MIXSELs (mode-locked integrated externalcavity surface emitting lasers) where the SESAM is integrated with the VECSEL gain element [210,[361][362][363][364], and colliding pulse mode-locking in ring cavities [365,366]. In addition, VECSELs have been mode-locked by synchronous pumping using a mode-locked Nd:YAG laser [367], mode-locked Ti:sapphire lasers [368,369], and fiber-amplified pump diodes [370]. Mode-locking could also be obtained using a Kerr lens or a combination of an SHG crystal and a dichroic mirror, provided that the pump diodes are modulated at the cavity repetition rate [66,371].…”

“…Saturable absorbers have also been integrated with the gain medium on the same semiconductor substrate for a very simple and compact implementation of a passively mode-locked VECSEL or MIXSEL [160,161]. Alternatively to saturable absorber passive mode locking, VECSELs have also been actively mode-locked by synchronous pumping with picosecond and femtosecond pulses from a Ti:sapphire laser [233]. The resulting chirped picosecond pulses were compressed down to 185 fs by a grating pair compressor.…”
