用一组闪光灯激发HCN气体，观察到激光振荡。输出特性已被认为是一致的，并发现在HC拉伸，v}中的初始吸收。然后，这种激发在碰撞弛豫期间重新分布，并在到达平衡的途中通过（>，+ v2）。后者是激光跃迁的上能级。在合适的压力范围内，增益足以克服低的长波长腔损耗。有趣的调制的输出发生时，气体用CO稀释。这被解释为弛豫振荡，其中CO参与存储的CN伸缩振动的振动能量，凭借几乎共振频率。结果与增益增量常数0.029m ~（-1）和35 ms的很长的视反转寿命一致。
Laser oscillation has been observed in HCN gas excited With a bank of flashlamps. The output characteristics have been considered and found to be consistent with initial absorption in the HC stretch, v}. This excitation is then redistributed during collisional relaxation and passes through (>,+ v2) on the way to equilibrium. The latter is the upper state of the laser transition. In the right pressure range gain is sufficient to overcome the low, long wavelength cavity losses. Interesting modulation of the output occurs when the gas is diluted with CO. This is explained as relaxation oscillations in which the CO participates in storing the vibrational energy of the CN stretching vibration by virtue of an almost resonant frequency. The result is consistent with an incremental gain constant 0.029 m" 1, and a very long apparent inversion lifetimeof 35 ms.
