Difference-frequency generation of tunable mid-infrared radiation in bulk periodically poled LiNbO(3).
A bulk, quasi-periodic phase-matched difference-frequency process is demonstrated in field-poled LiNbO(3). Continuous tunability of output radiation in the 3.0-4.1-microm wavelength range is achieved through grating rotation. A maximum mid-infrared output power of 0.5 mW is measured.
