Abstract

A tunable laser oscillator with a broadband emitting and thereby wavelength tunable laser medium. An optical resonator is provided for setting the wavelength of the laser radiation. Following the resonator is a device for spectral filtering and for producing a spectrally purer emitted laser radiation. An aperture is mounted in the path of the radiation following that device. The mechanism used for setting the wavelength of the laser radiation also forms the device for spectral filtering and for producing the spectrally purer emitted laser radiation. An optical arrangement is provided for feeding back the radiation leaving the resonator onto the joint mechanism and device.
