Abstract

A tunable laser oscillator, comprises a laser medium, an optical resonator, a wavelength selective element for adjusting the wavelength of a laser beam, and optical means for broadening the radiation in the resonator. The laser beam is decoupled from the resonator by means of an optical element after having passed the broadening means and prior to passing again through the laser medium. The laser beam is decoupled from the resonator such that its direction is independent of the beam wavelength.
