Diodengepumpter, frequenzverdoppelter Festkörperlaser

摘要

The invention relates to diode-pumped double-frequency solid state laser, in which all elements of the resonator as well as the internal resonator elements (laser crystal (6), mirror (11), frequency doubler (8)) are lodged in or on an angle or u-shaped profile (1), which is made as a solid part in a single milled piece or as a cast, pressed or sintered part of metal or ceramic, said profile comprising one or more partition walls (7a, 7b), which are part of the same piece as the angle or u-shaped profile, that is, which have no connecting points by means of screws or the like, and which give additional stability to the profile. Furthermore, said walls are lodged in or on the same element of the resonator or of the internal resonator elements (e.g. frequency doubler, mirror, laser crystal) and comprise openings (15) to allow passage of the laser mode and/or the laser radiation.
