摘要

#CMT# #/CMT# The system (100) has a resonator comprising a partially transmitting decoupler (120) with a decoupling degree of less than 50%. The decoupler is arranged relative to a resonator mirror (130) such that a portion of laser light incident from a resonator chamber passes the decoupler in another resonator chamber and fed back into the former chamber after reflectance at the mirrors. A wavelength-selective element (180) i.e. narrow-band interference filter, is arranged in a beam path of the decoupled portion in the latter chamber, where the system comprises a titanium ion-doped sapphire crystal. #CMT# : #/CMT# The interference filter is in a form of a Fabry Perot interferometer. The resonator is a standing wave resonator and a ring resonator. #CMT#USE : #/CMT# Laser system e.g. titanium, sapphire laser system and solid state laser system, for emission of laser light in quantum-optical application to generate magnetic traps or optical lattice and high-resolution spectroscopy application. #CMT#ADVANTAGE : #/CMT# The interference filter is arranged in the beam path of the decoupled portion in the resonator chamber, thus suppressing unwanted wavelengths and/or frequencies and/or modes in a spectrum, adjusting the laser system in a simple manner, and eliminating losses in the resonator. The laser system produces the laser beam in few laser modes with precise preset wavelength. The laser system is reset without changing larger interventions in the laser system between different wavelengths and/or wavelength ranges. The design of the laser system ensures stable laser operation of the laser system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic plan view of a laser system with a standing wave resonator arrangement. 100 : Laser system 102 : Cuboid housing 120 : Partially transmitting decoupler 130 : Resonator mirror 180 : Wavelength-selective element.
