High power and energy generation in a Nd:YAG single-crystal fiber laser at 1834 nm

收藏本文  分享

We report on a diode-end-pumped high-power and high-energy Nd:YAG single-crystal fiber laser at 1834 nm.Two 808 nm diodes injecting about 58 W pump power into the Nd:YAG fiber have generated 3.28 W continuouswave and 1.66 W Cr:ZnSe-based passively Q-switched lasers. Slope efficiencies with respect to pump powers are8.7% for the continuous-wave laser and 4.9% for the Q-switched laser. The extracted maximum pulse energy is about 266.9 μJ, and the corresponding maximum pulse peak power is 2.54 kW. (本文共计5页)......[继续阅读本文]
