摘要

介绍了kw级连续波CO2激光聚焦光束穿透液体并维持锁孔(KH)的实验研究和估计建模结果。从KH表面到大部分液体的蒸发和湍流对流热损失的条件是不同的。KH深度对换热条件的依赖性很大。

High-power CW CO2 laser beam channeled penetration into liquid

The results are presented of an experimental research and estimating modeling of kW-level CW CO2 laser focused beam penetration into liquid and sustaining keyhole (KH). The conditions of evaporative and turbulent convective heat losses from the KH surface to the bulk of the liquid were varied. A drastic dependence of KH depth upon heat exchange conditions was stated.
