The basic structure and the fundamental principle of semiconductor saturable absorption mirrors (SESAM) that are used for passive mode-locking solid-state lasers are introduced. By using these mode-locking devices on novel thin-disk solid state lasers and optically pumped vertical-external-cavity surface-emitting semiconductor lasers (OPSVECSEL) to obtain high average output power ultrashort pulses are stated, and it is emphasized that the study of high average output power ultrashort pulses laser can be accelerated greatly by using the quantum dot SESAM.
