Large-Scale 200-kW Laser Diode Pumping Module for Inertial Fusion Energy Driver HALNA

200 kW laser diode pumping module aimed for IFE driver was developed. The pumping optics for the uniform irradiation was applied to this module. As a result, 80% filling factor for the pumping distribution was achieved. The maximum peak power of 226 kW was obtained at the 150 μs pump duration. The E-O conversion efficiency over 50% was achieved.
