Diode-pumped semiconductor disk lasers (SCDLs), also known as optically-pumped semiconductor vertical-external-cavity surface-emitting lasers (OPS-VECSELs), are promising light sources for achieving high output power in combination with nearly diffra

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

Saturable absorber mirrors (SAMs) have found widespread application in the generation of ultrashort optical pulses and are one of the driving forces behind the all-solid-state revolution in femtosecond optics. While the design of the absorption prope

We present nonlinear optical studies of the non‐equilibrium carrier dynamics in InGaAs/GaAs quantum well structures. We exploit the free‐carrier and electron spin‐governed nonlinearities in pump‐probe and four‐wave mixing experiments to mea

The local lattice plane curvature of semiconductor disk laser devices were determined by a newly devel-oped X-ray spot mapping technique using white beam synchrotron radiation. This method is suited for in-situ studies of the dependence of both param

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 demonstr

Transform-limited pulses as short as 290 fs at 1036 nm are generated by a diode-pumped semiconductor disk laser. The all-semiconductor laser employs a graded-gap-barrier design in the gain section. A fast saturable absorber mirror serves as a passive

The authors investigate the spectral tuning of the exciton resonance of a surface quantum well saturable absorber mirror for the generation of subpicosecond pulses, employing an optically pumped semiconductor disk laser in the 1μm spectral range. Th
