Limitations of 2um, 100-watt Rod-Shaped Tm:YAG Lasers in Applications

However, currently reported 2um, 100-watt level rod-shaped Tm:YAG lasers both domestically and internationally have some limitations in application. Firstly, some laser system devices are complex and bulky, making it difficult to use in certain fields. Secondly, high-power output of some lasers is achieved at low cooling temperatures, which can cause condensation on the crystal end face and damage the optical coating layer, affecting the long-term operation capability of the laser.
