Picosecond optical pulse generation based on photonic band crystal lasers is a very promising application of this novel laser type. Mode-locking and direct modulation performance of lasers with different structure designs will be presented.
Optically-pumped semiconductor disk lasers (SDLs) promise to be versatile femtosecond sources, because they can be tailored for almost any wavelength. Very recently, by passive mode-locking of SDLs with a semiconductor saturable absorber mirror (SESAM), pulse durations as short as 290 fs and 260 fs were demonstrated in the 1-mum wavelength range. Here, we investigate the laser parameters important...
The femtosecond laser performance of an optically pumped InGaAs-AlGaAs disk laser emitting around 1.04 mum was studied. Using a saturable absorber with a surface-near quantum well, 190-fs-pulses were generated.
We report the shortest pulses (290 fs) obtained directly from semiconductor lasers. These were achieved using a passively mode-locked semiconductor disk laser with a graded-gap barrier design in the gain section operating near 1036 nm.
Summary form only given. This paper reports continuous-wave (cw) and passive mode-locked laser operation of diode-pumped semiconductor disk lasers based on gain sections with step and graded index designs, each containing 6 InGaAs quantum wells. Mode-locked laser operation is achieved applying both structures, using a V-shaped cavity including a fast saturable semiconductor absorber mirror. Results...
We discuss carefully characterized semiconductor disk lasers with high spatial and spectral homogeneity, exhibiting 23% conversion efficiency and a 540-mW output power for cw operation. Passive mode-locking with 1.5-ps pulse duration is also demonstrated.
