摘要：

In this paper, for the first time, we propose an LD-end-pumped thermal compensation Q-switched step concentration Tm:YAG laser. A novel step concentration Tm:YAG crystal is used as the laser medium to mitigate thesevere thermal effects typically encountered in single-doped Thulium crystals. To compensate the thermal lenseffect generated by the crystal, we insert a negative lens into the cavity. At a repetition frequency of 100Hz, anoutput energy of 7.82mJ with a pulse width of 152.4ns is achieved. The center wavelength is 2013.41nm, and the beam quality is characterize by M-x (2)= 1:34 and M-y(2)=1:39.
