利用标准具调谐的TEA-CO_2激光器的泵浦光，观察到了90多条来自CH3OH、CH2Cl2、C2H5OH、CF3Br3、HCOOH和D2O的新的FIR激光谱线。这些新的谱线是通过使用标准具有效激发而获得的，这使得我们能够将TEA-CO2激光器作为单模发射的可调谐光源来操作。此外，还发现许多以前报道的只有CW-CO2激光泵浦的FIR激光谱线也对CH3OH、HCOOH、CH3Br和CH3I产生了振荡。这些线和新发现的线是使用长度超过3m的具有高Q因子的FIR谐振器的结果。Q因子可以根据NH3的拉曼FIR激光发射的波形来计算。波形与理论预测值吻合较好。
Using the pumping light of a TEA-C02 laser with etalon tuning, we have observed more than 90 new FIR laser lines from CH3OH, CH2Cl2, C2H5OH, CF3Br, HCOOH, and D2O. These new lines are obtained from effective excitations using an etalon, which enables us to operate the TEA-CO2 laser as a tunable source with single-mode emission. Furthermore, it has been found that many FIR laser lines which were previously reported only with cw-CO2 laser pumpings also oscillate for CH3OH, HCOOH, CH3Br and CH3I. These lines and the newly discovered lines are the results of using an FIR resonator of more than 3 m in length which has a high Q-factor. The Q-factor can be calculated based on the waveforms of Raman FIR laser emissions from NH3. The waveforms are in good agreement with theoretical predictions.
