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.
