Abstract
A novel waveguide for difference frequency generation in the mid-IR spectral region at 3.52 μm is characterized. High mid-IR power of 15 mW and an external conversion efficiency of up to 19 %W-1 have been obtained. An optical beam propagation factor M2=1.18 was determined using the second moment method. A simple 2-f absorption spectra demonstrates the potential of this mid-IR source for high precision trace gas sensing applications.
