Abstract:

A bulk, quasi-periodic phase-matched difference-frequency DFG process in field-poled LiNbO3 bulk crystal permits continuous tunability of the output radiation in the 3.0-4.1 um wavelength range through grating rotation. DFG in QPM-LiNbO3 crystal, carried out using a NdYAG laser and a high power semiconductor laser at the quasi-phased matching QPM degeneracy point, results in an ultra wide 0.5 um acceptance bandwidth, permitting crystal rotation-free wavelength tuning of 4.0-4.5 um, with 0.2 mW output power at 4.5 um.
