title: Efficient generation of a three-primary-color laser from the second-harmonic emission of a Nd:YAG laser.
abstract: Laser emission, consisting of three primary colors, is generated by frequency conversions of the second-harmonic emission of a picosecond (120 ps) Nd:YAG laser by means of stimulated Raman scattering and subsequent four-wave Raman mixing in molecular deuterium. In the double-pass configuration, the fundamental beam (532 nm, 14.16 mJ, 100%) is converted to blue (459 nm, 1.71 mJ, 12.1%), green (532 nm, 7.04 mJ, 49.7%), and red (632 nm, 4.90 mJ, 34.6%), resulting in a total conversion efficiency of 96.4%.
