摘　　要：在近红外光谱区，可调谐的ＣＯ激光器是激光光谱分析中不可缺少的光源．ＣＯ激光器的光谱覆盖范围在光谱分析中直接影响可分析物质的种类和灵敏度．基频（Δｖ＝１跃迁）ＣＯ激光器的光谱范围已经实现从ｖ＝１→０到ｖ＝３７→３６振动－转动带跃迁，即波长范围为４．８～...A LN 2 cooled CW CO overtone laser has been carried out for extending spectral coverage of tunable CW CO laser in short wavelength region. As many as 9 vibration rotation transition bands have been observed in wavelength region of 3.4 4.0 μm. The maximum power of 55 mW was obtained for single line operation. The typical parameters of the laser optical resonator and laser plasma are given. Further extension in short wavelength region is expected when some modifications have been made.
