Abstract
With the scope of future inertial fusion energy (IFE) driver, design of
a diode-end-pumped 1-kJ zig-zag slab laser with cryogenically cooled
ceramic Yb:YAG is presented. Pulse repetition rate is 16 Hz, and
optical-optical efficiency is 34 % at 140 K operation. Gradient of
Yb3+ ion density increasing toward the slab center
successfully suppresses the parasitic on the slab ends.
