Abstract
A bulk, quasi-periodic phase-matched difference-frequency (DFG) process in field-poled LiNbO bulk crystal permits continuous tunability of the output radiation in the 3.0-4.1 &mgr;m wavelength range through grating rotation. DFG in QPM-LiNbO crystal, carried out using a Nd:YAG laser and a high power semiconductor laser at the quasi-phased matching (QPM) degeneracy point, results in an ultra wide 0.5 &mgr;m acceptance bandwidth, permitting crystal rotation-free wavelength tuning of 4.0-4.5 &mgr;m, with 0.2 mW output power at 4.5 &mgr;m.
