59%-efficient cw-modelocked second harmonic generation of blue light in backswitch-poled lithium niobate

Summary form only given. We demonstrate cw modelocked second harmonic generation of blue light in 0.5-mm-thick backswitched periodically-poled LiNbO/sub 3/ (PPLN). We backswitch-poled 4-/spl mu/m-period gratings in 76-mm-diameter 0.5-mm-thick congruent z-cut LiNbO/sub 3/ wafer substrates. PPLN sampl...

Zusammenfassung:Summary form only given. We demonstrate cw modelocked second harmonic generation of blue light in 0.5-mm-thick backswitched periodically-poled LiNbO/sub 3/ (PPLN). We backswitch-poled 4-/spl mu/m-period gratings in 76-mm-diameter 0.5-mm-thick congruent z-cut LiNbO/sub 3/ wafer substrates. PPLN samples, ranging in length from 0.5 to 50 mm, were obtained from these wafers. Using a cw-modelocked Ti:sapphire pump laser, uncoated PPLN samples were characterized for single-pass SHG efficiency. Conversion efficiencies of 43% and 59% were achieved from the 0.5-mm and 12-mm length samples, respectively.
