Q-Switched Tm：YAG Laser Intracavity-Pumped by a 1064nm Laser

We report a Q-switched 2-μm Tm：YAG laser based on intracavity-pumped by a 1064-nm Nd：YAG laser operating at room temperature for the first time. An average output power of 5.1W is obtained with the repetition rate of 30kHz and a pulse width of 300ns. In addition, we demonstrate a 12.5-W continuous-wave 2-μm Tm：YAG laser, which is, to our best knowledge, the highest power for intracavity-pumping configuration.

The essential goal of that paper （Chin. Phys. Lett. 26（2009） 124211） was to obtain a 2μm Tm：YAG laser with short pulse output. A Q-switched technique is used to realize the short pulse output in our laser system. The idea presented by Dr. Nieolaie Pavel is right. In our work, the directly Q-switched 2μm Tm：YAG pulse laser is not realized. As a matter of fact, the Q switch is used to directly switch the 1μm Nd：YAG laser.
