摘要：

Continuous-wave mid-infrared radiation near 3.5 mu m is generated by difference-frequency mixing of the output of a compact 1.1-1.5-mu m dual-wavelength fiber amplifier in periodically poled LiNbO3. The diode side-pumped amplifier is constructed with double-cladding Yb-doped fiber followed by single-mode Er/Yb codoped fiber. Output powers of as much as 11 mu W at 3.4 mu m are obtained, and spectroscopic detection of CH4 and H2CO is demonstrated. (C) 1998 Optical Society of America.
