We achieve efficient difference frequency generation in direct-bonded quasi-phase-matched LiNbO3 waveguides. Mid-infrared light sources in the 2-4$\mu$m bands are obtained with communication band laser diodes. There are many strong absorption lines in the wavelength range originating mainly from normal vibration modes of environmental gasses such as greenhouse effect gasses. Therefore, a drastic improvement in the sensitivity is expected in trace gas detection. We show simultaneous detection of CO isotopomer absorption spectra in the 2.3$\mu$m band with a broadband mid-infrared generation utilizing the feature of small LiNbO3 material refractive dispersion. We also show the detection of ambient CO2 and CH4 absorption spectra with multi-pass cells in the 2.7$\mu$m and 3.3$\mu$m bands. Additionally, the mid-infrared optical axis is easily adjusted in our setup using input collinear near-infrared lights. |
