Abstract
It was experimentally found that speeds of hot submerged jets appearing in case of laser induced nucleation boiling of water near the tip of optical fiber submerged in water decrease exponentially with increasing laser power (heat flux). This result was obtained for a closed cylindrical cuvette where hot jets collided with walls and slipped the cuvette boundary transferring heat to it. The obtained result is to be taken into account in performing precise laser–induced surface cleaning inside confined volumes, in developing medical technologies for laser therapy of pathologically changed vessels or cysts, and in other applications.
液体表面沸腾在激光加热器上产生的射流动力学特征
摘要 实验发现，当激光诱导浸没在水中的光纤顶端附近的水成核沸腾时，出现的热浸没射流的速度随着激光功率（热通量）的增加呈指数下降。这一结果是在一个封闭的圆柱形比色皿中得出的，热射流与比色皿壁碰撞并滑过比色皿边界，将热量传递给比色皿。在对密闭空间进行精确的激光诱导表面清洁、开发用于激光治疗病变血管或囊肿的医疗技术以及其他应用时，应考虑到这一结果。

期刊介绍：
Technical Physics Letters is a companion journal to Technical Physics and offers rapid publication of developments in theoretical and experimental physics with potential technological applications. Recent emphasis has included many papers on gas lasers and on lasing in semiconductors, as well as many reports on high Tc superconductivity. The excellent coverage of plasma physics seen in the parent journal, Technical Physics, is also present here with quick communication of developments in theoretical and experimental work in all fields with probable technical applications. Topics covered are basic and applied physics; plasma physics; solid state physics; physical electronics; accelerators; microwave electron devices; holography.
