This paper will review and discuss pico-and femtosecond pulse generation from passively
modelocked vertical–external-cavity surface-emitting semiconductor lasers (VECSELs). We …

The performance of ultrafast semiconductor disk lasers has rapidly advanced in recent
decades. The strong interest from industry for inexpensive, compact, and reliable ultrafast …

This graduate-level textbook starts with Maxwell's equations. If the reader finds this
reasonable, this book should be helpful. Focusing on ultrafast solid-state laser oscillators …

We investigate the relationship between passive mode locking and the formation of time-
localized structures in the output intensity of a laser. We show how the mode-locked pulses …

We review progress in the development of an unconventional type of semiconductor laser
that has become the focus of much attention in recent years. The vertical-external-cavity …

Edge-emitting mode-locked quantum-dot (QD) lasers are compact, highly efficient sources
for the generation of picosecond and femtosecond pulses and/or broad frequency combs …

Surface-emitting semiconductor lasers can make use of external cavities and optical
pumping techniques to achieve a combination of high continuous-wave output power and …

We have developed optically pumped passively mode-locked vertical-external-cavity
surface-emitting lasers. We achieved as much as 950 mW of mode-locked average power in …

High-power ultrafast lasers are important for numerous industrial and scientific applications.
Current multi-watt systems, however, are based on relatively complex laser concepts, for …

We present two novel semiconductor saturable absorber mirror (SESAM) designs which can
exhibit more than ten times lower saturation fluence than classical SESAM devices. Design …
