Rg. Batchko et al., Continuous-wave quasi-phase-matched generation of 60 mW at 465 nm by single-pass frequency doubling of a laser diode in backswitch-poled lithium niobate, OPTICS LETT, 24(18), 1999, pp. 1293-1295
We report continuous-wave single-pass second-harmonic generation (SHG) in 4
-mu m-period 0.5-mm-thick backswitch-poled lithium niobate. Pump sources at
920-930 nm include both Ti:sapphire and diode-oscillator-amplifier lasers.
SHG of a Ti:sapphire laser at 6.1%/W efficiency, producing 61 mW of power
at 460 nm, is demonstrated in 50-mm-long periodically poled lithium niobate
samples with a nonlinear coefficient d(eff) approximate to 9 pm/V, and 60
mW at 465 nm and 2.8%/W efficiency is obtained by SHG of a laser-diode sour
