説明

By exciting 10-atm He/F2 gas mixtures by electric discharge at 66MW/cm3, a specific output energy of 2.9J/1 (83mJ) has been obtained in the F2 laser (157.6nm). To extend an available laser wavelength region with high output laser energies in the vacuum ultraviolet, frequency conversion of the laser radiation by stimulated Raman scattering in H2 has been demonstrated for the first time. The laser energy focused into a Raman cell was about lOmJ (22ns FWHM), which corresponds to the focused intensity of 141MW/cm . At H2 pressure of 5atm, 1st and 2nd Stokes lines (168.6nm, 181.4nm) and 1st anti-Stokes line (147.9nm) were observed. The energy conversion efficiency was ~10% for the 1st Stokes line, ~ 2% for the 2nd Stokes line, and ~ 0.8% for the 1st anti-Stokes line at a l0atm H2.
