Abstract: Holders of the active elements of a multi-disk multipass amplifier with a liquid-free closed cryogenic cooling cycle are modified. The equilibrium temperature of the active elements is experimentally investigated in relation to the power of diode pumping for the modified crystal holders. The dependence of the gain coefficient on the temperature of the active elements is measured. A smallsignal gain of up to 1.2 is obtained in a single pass through the active element.

Keywords: diode pumping, high-peak-power laser system, high pulse-repetition rate, cryogenic temperatures, laser amplifier.
