Large-aperture Ce 3+ :LiCaAlF 6 power-amplifier module development for the TW ultraviolet femtosecond CPA laser system

Hidetoshi Murakami; Shingo Ono; Yuji Suzuki; Toshimasa Kozeki; Hideyuki Ohtake; Nobuhiko Sarukura; Hiroki Sato; Susumu Machida; Kiyoshi Shimamura; Tsuguo Fukuda

Coaxially-pumped large-aperture Ce3+:LiCaAlF6 power-amplifier module for the TW ultraviolet CPA laser system is demonstrated to have 98-mJ output with 25% extraction efficiency. Additionally newly-in vented homogeni zed- gain, side-pump, power-amplifier scheme for further energy scaling is successfully operated.

High-average power mode-locked Ti:sapphire laser with newly-invented intra-cavity cm-amplification scheme

Zhenlin Liu; Shinji Izumida; Shingo Ono; Hideyuki Ohtake; Nobuhiko Sarukura

We have demonstrated high-average power mode-locked Ti:sapphire laser with newly-invented intra-cavity cw-amplification scheme. This scheme can be applicable for the power scaling of other lasers.
