Ml. Sundheimer et al., SIMULTANEOUS GENERATION OF RED, GREEN AND BLUE-LIGHT IN A SEGMENTED KTP WAVE-GUIDE USING A SINGLE-SOURCE, Electronics Letters, 30(12), 1994, pp. 975-976
Guided white light output has been generated in a quasi-phasematched K
TP waveguide. Red (825nm), green (550nm) and blue (412.5nm) coherent r
adiation is obtained through simultaneous second-harmonic generation,
sum-frequency generation, and fourth-harmonic generation of a single l
aser source at 1650nm.
