Abstract
We present a CPA-free picosecond laser that will pave the way to cost effective industrial micromachining by operating not only at high pulse energy but also at significantly higher average output power than previously achieved in commercial ultrafast systems. The laser is based on a regenerative amplifier using a state-of-the art thin-disk laser head, and includes an external modulator for user-adjustable pulse energy. 80 W of average power are demonstrated at a repetition rate of 200 kHz and a duration of about 7 ps.
