Krypton-fluoride (KrF) Iaser is one of the promising driver for inertial confinement fusion because of its short wavelength, broad band width, high efficiency and capability of high repetition-rate operation. A high gain double-pass amplifier can yield a high, heavily saturated output intensity (5 to 6 times saturation intensity, > 10MW/cm^2) with nearly maximum efficiency (> 10%) and high stage gain (> 50) at the same time. The high gain can be achieved by cylindrical electron-beam pumping configuration without external magnetic field. Angular pulse multiplexing enables efficient pulse compression and amplification of beams with broad spectral width. The broad band width is required for irradiation smoothing methods. BRP (broad-band Random Phase Irradiation) or ISI (Induced Spatial Incoherence) . Multi-kJ KrF laser, Super-ASHURA (Electrotechnical Laboratory, 8kJ) , NIKE (at Naval Research Laboratory, 3kJ) and TITANlA (Rutherford Appleton Laboratory, 2kJ) are being developed and close to completion.
