Overview of the HiLASE project is reported. Development of high-power, picosecond laser sources is desirable for industrial, scientific, and medical applications. The framework of the Research Program 1 (RP1) of the HiLASE project is to develop both the 500-mJ at 1-kHz repetition rate and the 5-mJ at 100-kHz repetition rate laser systems with 1 2ps pulse duration based on thin disk technology. The front-end of our laser system contains a regenerative amplifier as the first stage of amplifier

The average power of 50-W of the high repetition rate amplifier has been achieved at the repetition rate of 100-kHz. Also, we have obtained the output energy of 45-mJ at the repetition rate of 1-kHz from the high energy amplifier. The measured M 2 of amplified beam was 1.2.
