A study on the amplification of active-mirror Yb:YAG lasers

Xiaojin Cheng, Fei Xu, Jianhua Shang, Chao Li


Thermal effects and amplified spontaneous emission (ASE) are two main factors in the design of high-power and high-energy laser amplifiers. The temperature distribution and the lateral ASE of the face-pumped active-mirror Yb:YAG amplifiers are analyzed with finite element analysis software. An amplifier with an output energy of 100 J was designed to illustrate energy scaling of the face-pumped active-mirror structure.
