Paper Abstract

Tm:YAG laser, the wavelength is 2.01μm which is safe for eyes, has very important application at Coherent Laser Radar and surgical medical, and is a kind of ideal laser scalpel. As its wavelength is adjacent to the water absorption peak, the laser energy can be absorbed strongly by water, thus the effect of surgical cutting and evaporation is better than traditional methods, and bring smaller surrounding tissue injury, effective vascular incision condensation. Otherwise, the laser can be carried by ordinary silica fiber. Summarily, Tm:YAG laser is quite suitable for high-precision surgery. In the high-power case, Side-pumped instrument is an efficient one. Then how to select the parameters of the structure of side-pumped laser system has important practical significance for improving the laser performance. For the development and optimization of laser system, rate equation model of quasi-three rank energy levels was used to simulating the absorption process of side-pumped optical by media, laser threshold, efficiency and optimal parameters of activation medium. The results showed that Tm: YAG laser's output energy can achieve the maximum average output power of about 110W under the given parameters. The work can be referred to practice laser performance.
