Paper Abstract

We are developing one joule energy and one picosecond pulse duration laser system at the repetition rate of 120 Hz based on Yb-doped solid-state materials. The amplified output from the thin disk regenerative amplifier is amplified by a cryogenically conduction cooled single slab amplifier. In this work, we also present a new measurement method of a gain distribution insensitive to mode matching. One of the advantages of this method is a fact that it provides real dimensions of the gain distribution. Knowledge about it allows one to find the optimum spatial mode matching to maximize the output energy.
