Abstract: The use of reflecting surfaces that are inclined towards one another enables the multiple reflection of a beam path to be achieved in a laser structure. This permits the realization of compact laser assemblies. The introduction of beam-influencing media between the reflective surfaces or the configuration of said reflective surfaces from or using media of this type allows the use of the multiple reflection for influencing parameters of the radiation or radiation field.

Abstract: The solid state laser comprises a laser gain medium (1), pumping means for pumping the laser gain medium, and a laser cavity having a first end (3) and a second end (17), wherein the laser gain medium is at, or in the vicinity of, said first end (3) of said cavity. A semiconductor saturable absorber mirror (SESAM) can be placed at the second end (17) of the cavity. The laser gain medium can comprise at least one face for receiving pumping energy from the pumping means, the face being made reflective at a laser frequency of the laser, so that it can form the first end of the laser cavity. The resulting setup used for generating femtosecond laser pulses.
