Continuous-Wave Tunable Midwave Infrared Generation Near 4.5 micrometers with an Intracavity Optical Parametric Oscillator and Difference Frequency Generation

Abstract

Continuously tunable cw emission near 4.5 micrometer was generated by difference frequency generation (DFG) within a Nd:YAG pumped optical parametric oscillator (OPO). The periodically poled lithium niobate crystal used for DFO contained eight grating bands that enabled wavelength tuning between 4.25 and 5.65 micrometer. As much as 90 mW of power at 4.48 micrometer was achieved for 16.7 W of pump.
