Yq. Lu et al., FREQUENCY-DOUBLING A CW DIODE-LASER TO GENERATE 489 NM BLUE-LIGHT IN OPTICAL SUPERLATTICE LINBO3, Electronics Letters, 32(4), 1996, pp. 336-337
The generation of 489nm blue light by direct frequency doubling a CW 9
78nm InGaAs diode laser radiation was demonstrated in optical superlat
tice LiNbO3 crystals al room temperature. When the incident power was
150, 1.35mW and 1.0mW blue lights were achieved in the samples with an
d without an enhancement cavity, respectively.
