Abstract
The present invention is directed to a laser resonator emitting visible radiation with reduced speckle noise, wherein said optical resonator is formed by at least two mirrors at both ends of a visible radiation emitting lasing material, wherein that optical resonator enhances multimode operation, so that said visible radiation emitting lasing material emits a spectrally broadened visible radiation, wherein the enveloping function of said spectrally broadened visible radiation has a full width at half maximum (FWHW) within 1 nm to 15 nm.
