The copper vapor laser is a pulsed gas laser which emits energy in two wavelengths simultaneously: 510.6 nm (green) and 578.2 nm (yellow). Each pulse has a duration of 15 nsec, maximal energy of 3 mJ and a peak power of more than 100 kW. It is a variably high repetition rate laser, in the range between 1 kHz and more than 20 kHz. We studied its interaction with the rabbit retina, while using two different repetition rates, 4 kHz and 18 kHz. The histological analysis of the lesion produced by 4 kHz repetition rate showed undesired retinal effects, similar to those caused by other pulsed lasers. On the other hand, the histological examination of the lesion produced by the 18 kHz repetition rate showed a desired coagulation effect, limited to the outer retinal layers, and comparable to a lesion produced by a continuous wave (CW) laser.
铜蒸气激光器是一种脉冲气体激光器，它能同时在两个波长发射能量：510.6纳米（绿色）和578.2纳米（黄色）。每个脉冲的持续时间为15纳秒，最大能量为3毫焦，峰值功率超过100千瓦。它是一种可变高重复率激光器，重复率范围在1千赫兹至20千赫兹以上。我们研究了它与兔视网膜的相互作用，使用了两种不同的重复率，即4千赫兹和18千赫兹。对4千赫兹重复率产生的损伤进行组织学分析，发现有不理想的视网膜效应，类似于其他脉冲激光器所造成的效应。另一方面，对18千赫兹重复率产生的损伤进行组织学检查，发现有理想的凝固效应，仅限于视网膜外层，且与连续波（CW）激光器产生的损伤相当。
