Thirty-four new FIR lasing lines are reported in vinyl chloride optically pumped by a CO2 laser. Ten of them are observed when using pump lines belonging to the 10.8 μm hot band. 相似文献

53 new CW FIR laser lines are reported in 1,1-difluoroethane optically pumped near 10 μm by CO2 and N2 O lasers. The emission spectrum initially reported in the literature consisted of four lines between 770 and 458 μm and has now been extended to the 2.39 mm- 319 μm region. The reason for this extension, especially to the long wavelengths, is analyzed. 相似文献

Fifteen new CW FIR laser lines are reported from Stark tuned CO2 optically pumped CH3 OH and CH3 OD. Four new CW laser lines have also been observed from zero field optically pumped CH3 OD, three with a CO2 laser, and one with an N2 O laser. 相似文献

A crossed waveguide type varactor frequency doubler is described here which gives a conversion efficiency of 39% and a 4-GHz bandwith (-1 dB) around 40 GHz for 100-mW input power. Gallium arsenide varactor diodes in commerical packages are used, permitting great flexibility, in particular in molecular spectroscopy experiments. 相似文献
