Q-switching and quasi-phase-matching using a domain structured LiNbO 3 crystal

We report a device that acts as an active Q-switch and a quasi-phase-matching structure. It is a domain-structured LiNbO crystal, where the Q-switching is performed by electro-optic deflection and the wavelength conversion is produced by quasi-phase-matched optical parametric generation.

Summary:We report a device that acts as an active Q-switch and a quasi-phase-matching structure. It is a domain-structured LiNbO crystal, where the Q-switching is performed by electro-optic deflection and the wavelength conversion is produced by quasi-phase-matched optical parametric generation. By introducing this device into a diode-pumped Nd:YAG laser we obtained pulses at 1064 nm (~10 ns FWHM, 195 µJ) and 1617 nm (~3 ns, 15 µJ).
