Tunable quasi-phase-matched optical parametric generator by translating a segmented crystal
Optics Communications(2007)
摘要
A simple way to realize a fast tunable quasi-phase-matched optical parametric generation without crystal rotation, temperature changing or multi-grating periodically poled crystal translation is presented. The key is to translate a segmented crystal which is stacked by a lithium niobate crystal with three teeth and a single grating periodically poled crystal. The signal wavelength is tunable near 1.55μm with the signal power of ⩾90mW.
