Abstract
High-efficiency short-wavelength KrF lasers have been developed for an inertial confinement fusion experiment.1 The atmospheric pressure operation of the KrF laser can solve important technical problems in establishing a reliable large MOPA system. We proposed atmospheric pressure operation of the KrF laser and then found experimentally and theoretically that both such a laser and amplifier pumped at high excitation rates can operate efficiently.2,3 The 193-nm ArF laser is better than the 248-nm KrF laser for efficient absorption by a fuel pellet and moreover was reported to be more efficient than the KrF laser at the same excitation rate of 2.3 MW/cm3.4
