摘要
The apparatus for generating at least visible light beams of different output wavelengths for display purposes comprises a passively mode-locked solid-state thin-disk laser (1) and means for at least partially converting said primary light beam into electromagnetic radiation characterized by said at least three different output wavelengths including an optical parametric oscillator (OPO) (23). The OPO is preferably an optical fiber feedback OPO. An optical fiber feedback OPO comprises a nonlinear optical element (32) and feedback means (35-40) for feeding back at least a proportion of the radiation emitted by the nonlinear medium to the nonlinear element, wherein the feedback means comprise an optical fiber (37).
