Limitations of 2um, 100-Watt Rod-Shaped Tm:YAG Lasers in Application

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