放电管作为电激励连续波HF/DF激光器的F原子发生器,在整个激光器系统中占有重要地位。目前流行采用的是高压直流电源加镇流电阻的放电模式,典型电参数为接近10kV高电压、百毫安量级的低电流。传统理论和实验结果均认为:放电管F原子产率与放电管注入功率成正比,从而激光器输出功率也应与之成正比。引入不同阻值的镇流电阻,发现对于相同的注入功率,低电压、大电流模式比高电压、小电流模式更容易获得高的功率输出。 The discharge tube, as an F-atom generator for electrically excited continuous wave HF / DF lasers, plays an important role in the overall laser system. Currently popular is the high-voltage DC power supply plus ballast discharge mode, the typical electrical parameters close to 10kV high voltage, 100 milliampere-level low current. The traditional theory and experimental results agree that the F atom of the discharge tube is proportional to the injection power of the discharge tube, so the output power of the laser should also be proportional to it. The introduction of different resistance of the ballast resistor found that for the same injection power, low voltage, high current mode than high voltage, low current mode more easily obtain high power output.
