We are developing a high average power laser system using Yb:YAG thin-disk amplifiers. Currently picoseconds pulses with 10 mJ energy are delivered from the regenerative amplifier at repetition rate of 1 kHz. The pulse energy will increase up to 100 mJ by a Yb:YAG thin-disk multi-pass amplifier. The picosecond pulses have been used in several applications such as intense THz light wave generation, laser induced damage test, and so on. I will present details of the laser system and preliminary results of applications.
