A repetitive, tunable, high-power vacuum ultraviolet laser operating on the 172-nm bound-free transition in xenon has been developed for use in photochemistry, selective excitation spectroscopy, and in the generation of coherent radiation in the XUV spectral region. A compact high-voltage generator is employed in conjunction with a coaxial cold-cathode diode to pump high-pressure xenon at a repetition rate of up to 10 Hz, though at present gas heating limits the operation of the laser to 0.5 Hz. The apparatus has been designed for compatibility with fluorine, and is consequently a suitable pumping source for the rare gas halide exciplex lasers. The gas handling techniques which enabled reliable, reproducible laser action to be achieved in xenon for several hundred pulses are described.
已研制出一种重复频率可调的高功率真空紫外激光器，它利用氙气中172纳米的束缚-自由跃迁，用于光化学、选择性激发光谱学以及在极紫外光谱区域产生相干辐射。一种紧凑的高压发生器与同轴冷阴极二极管配合使用，以高达10赫兹的重复频率泵浦高压氙气，不过目前气体加热将激光器的运行限制在0.5赫兹。该装置设计为与氟兼容，因此是稀有气体卤化物准分子激光器的合适泵浦源。文中描述了在氙气中实现数百个脉冲的可靠、可重复激光作用的气体处理技术。
