Abstract :
High power laser becomes a key component for the scientific and industry applications. Above all, diode-pumped solid state lasers (DPSSLs) play an important role in inertial fusion energy (IFE) and related high-energy applications as well as material processes. In these applications, repeatable operation (several Hz ~ 100 Hz) is indispensable. In this paper we present the diode-pumped zig-zag slab laser. Average power of 213 W (21.3 J at 10 Hz) was successfully achieved. The diffraction limited focusability was achieved by use of SBS phase conjugator. These results have indicated the 100-J scalability of slab architecture and the 1-kW average power potential of repeatable operation up to 10 Hz for high-energy applications.
