利用四臂腔产生单纵模TEA CO2激光的研究
Investigation of Four-Arm Cavity for Generating Single Longitudinal Mode Operation of TEA CO2Laser
摘要
提出一种新的TEA CO2激光器选单纵模的方法－四臂腔选单纵模。在理论上研究了这种新腔型的反射率的选频特性并预测了其选单纵模的能力。实验中，用此腔型得到了能量达225 mJ稳定的单纵模TEA CO2激光输出，且单纵模再现率超过90％。
Abstract
A new method for generating single longitudinal mode operation of TEA CO2 laser-using four arm cavity to select single longitudinal mode is proposed. The new cavity’s reflectivity character has been theoretically studied, and its mode selectivity is predicted. In experiment, single longitudinal mode TEA CO2 laser pulses are readily achieved using this method, with laser pulse energy up to 225mJ and single longitudinal mode repetition more than 90%.
