Abstract

Recent advances in high-power injection-seeded lasers, pulse amplified dye lasers, and four-wave mixing technologies make possible the development of high-power, broadly tunable, and ultranarrow sources in the UV, VUV, and XUV regions. By combining the latest technological advances in these areas we have developed a near-transform-limited laser source that tunes from 74 to 1000 nm with peak powers of >150 MW in the visible and >30 MW in the ultraviolet and has more than 1012 photons/s in the VUV-XUV region. The bandwidth in the XUV below 100 nm is mea sured to be 210 MHz. The spectral brightness of 1.5 × 10¹⁷ photons/s/0.1 % bandwidth of this tabletop laser source is several orders of magnitude higher than the best sources available today.
