Short Wavelength Generation Using Excimer Lasers

High spectral brightness KrF* (249 nm) and ArF* (193 nm) excimer laser sources have been used in a variety of experiments to test the generation of coherent short wavelength radiation (λ ti 100 nm) using nonlinear processes. These experiments include harmonic generation, sum frequency mixing, two and four photon pumping of lasers as well as spectroscopic application of such short wavelength radiation and the study of nonlinear coupling at intensities of up to ≈ 1017 W/cm2.
