摘　　要：利用反射光栅调谐的脉冲ＴＥＡＣＯ２激光１０Ｒ（６）泵浦０．２ｍ长的小型ＮＨ３分子远红外激光器，当泵浦能量为１．１Ｊ、ＮＨ３分子气压为０．９ｋＰａ时，产生２９８μｍ的新谱线，对应Ｖ２：ａＲ（０，０）。By using a grating tuned pulsed TEA CO 2 laser with 10R(6) line to pump NH 3 molecules in a miniature ASE cavity of 0.2 m in length,when the pumping energy was about 1.1 J and the pressure of NH 3 molecular gas was about 0.9 kPa,a new line with wavelength about 298 μm which may be a stimulated Raman line of V 2: aR(0,0) transtition was found.
