Arrangement for generating red, green and blue laser radiation

Abstract

An arrangement which generates red, green and blue laser radiation comprise a laser radiation source whose first beam (λl) is split in the infrared wavelength range, wherein the first part of this beam is frequency-doubled and green light (λG) results and another part is used to generate light of the primary colors red (λR) and blue (λB). Another part of the first beam (λl) is fed to a wavelength converter which generates another beam (λ2, λ4) in the infrared wavelength range which has a greater wavelength than the first beam (λl), further, the colors red (λR) and blue (λB) result from the further beam (λ2, λ4) or from a part thereof by another nonlinear process by sum frequency mixing or by frequency doubling or by sum frequency mixing and frequency doubling.
