摘要：

We report a rapid and random wavelength-tuned mid-infrared (1R) light source with difference-frequency generation, using an electronically tuned dual-wavelength-oscillated Ti:Al(2)O(3) laser. A tuning range from 5.4 to 8.2 mu m is achieved. The wavelength stability of the mid-IR radiation is measured to be less than +/- 1.1 x 10(-3) mu m, and we realize rapid and random wavelength tuning with the switching speed of 1 ms. Using the light source, the real-time monitoring of acetone vaporization is demonstrated with absorption at 7.33 mu m, compared with water with absorption at 6.25 mu m. The results show that our mid-IR light source is attractive for multi-wavelength spectroscopic applications. (C) 2010 The Japan Society of Applied Physics
