研制了一台紧凑型连续HCN激光器，特别注意了影响稳定性和高功率输出的因素。该激光器在直径为5厘米的温控管中使用1米长的放电。向气体混合物中添加大比例的氦气导致在升高的管温度下产生高功率输出，并在数十小时内完全清洁地运行。在冷却的侧臂中使用热钽阴极获得了稳定的放电。该激光器在337 μ m处产生20 mW的连续输出，在30 kHz的总带宽内信噪比优于100。体积功率输出为90 μW cm−3。
A compact cw HCN laser has been developed with particular attention to the factors which affect stability and high power output. The laser uses a 1 meter long discharge in a 5 cm diameter temperature controlled tube. The addition of a large proportion of helium to the gas mixture leads to the production of high power output at elevated tube temperatures and perfectly clean operation for several tens of hours. A stable discharge is obtained by using a hot tantalum cathode in a cooled sidearm. The laser produces 20 mW of continuous output at 337 υm with a signal-to-noise ratio better than 100 in a total bandwidth of 30 kHz. The volumetric power output is 90 μW cm−3.
