Abstract :
The generation of 489 nm blue light by direct frequency doubling a CW 978 nm InGaAs diode laser radiation was demonstrated in optical superlattice LiNbO3 crystals at room temperature. When the incident power was 150, 1.35 mW and 1.0 mW blue lights were achieved in the samples with and without an enhancement cavity, respectively
