Nonlinear properties of silica and air for picosecond ultraviolet pulses
The nonlinear power limiting processes in silica and air are investigated for picosecond pulses at the KrF wavelength. The two-photon absorption coefficient and the nonlinear refractive index in silica are measured to be 0.06cm / GW and 1.7 x 10<sup>-13</sup> e.s.u. respectively. A mecha...

| 520 | |a The nonlinear power limiting processes in silica and air are investigated for picosecond pulses at the KrF wavelength. The two-photon absorption coefficient and the nonlinear refractive index in silica are measured to be 0.06cm / GW and 1.7 x 10<sup>-13</sup> e.s.u. respectively. A mechanism for the rapid spectral broadening in air based on Raman-enhanced four-wave mixing is proposed. Experimental evidence supporting this hypothesis is presented. | ||
