A Tunable Mid-IR light source base on single resonant Difference Frequency Generation (DFG) is experimentally investigated. The DFG process is pumped by an 800 nm tunable tapered diode laser. Grating feedback to the single mode channel of the tapered diode narrows the spectrum and allows for tuning of the diode laser wavelength by rotating the grating.

The system tunes 500 nm using a single diode, ranging from 2.9 μm to 3.4 μm with mW’s of output power over the entire range. The maximum measured output is 2.5 mW at 3.2 μm.
