High Power Visible Radiation from a Raman Shifted XeF(C—A) Excimer Laser

Efficient wavelength shifting by means of stimulated Raman scattering (SRS) in hydrogen and liquid nitrogen of the blue-green XeF(C—A) excimer laser was demonstrated. Energy conversion into the first Stokes line with an efficiency of 38 % was achieved. Continuously tunable radiation from 523- 579 nm and from 578- 650 nm with pulse energies ranging from 100 mJ to 210 mJ was generated in liquid nitrogen and hydrogen, respectively. A peak power of 35MW at 549.0 nm was obtained. 1
