“…The values of γ for presently available silicate, phosphate, and fluorophosphate glasses used for optical components and amplifier media range from 2.0 × 10 −20 to 4.0 × 10 −20 m 2 ∕W [13][14][15][16][17][18][19][20][21][22][23]. The results of our work reported here, however, have significantly smaller values.…”

By performing the Z-scan measurements at 800 nm using a femtosecond pulsed laser, we are able to characterize the nonlinear refractive indices of Nd, Y codoped CaF(2) and SrF(2) crystals. Based on our measured results, we conclude that the doped fluoride crystal possesses a small nonlinear refractive index and the doping of Nd(3+) and Y(3+) ions in CaF(2) can change its third-order nonlinear index, but the contribution is minor. The doped fluoride crystal may have large potential to be developed as the next generation of gain material for a high-energy laser system.

We report an experimental and numerical investigation of third-and fifth-harmonic generation in a CaF 2 crystal with 20 fs (three-optical-cycle), 2 μm driving pulses. The double-peaked temporal profile of the third-harmonic pulse and its propagation dynamics was captured by means of the cross-correlation technique, showing that the third-harmonic pulse naturally consists of free and driven components propagating with different group velocities, and which occur without the splitting of the driving pulse at the fundamental frequency. Relevant characteristics of the harmonics generation process, such as the harmonics spectra, energy oscillations, and conversion efficiency, were measured as functions of propagation length and input-pulse energy and intensity. Our results demonstrate that the fifth harmonic is generated solely via cascaded four-wave mixing between the fundamental and third-harmonic frequency pulses due to cubic nonlinearity, without any detectable contribution of six-wave mixing due to quintic nonlinearity in the process.

“…The nonlinear refractive index and the third-order electronic susceptibility v ð3EÞ 1111 have been measured in some alkali halide crystals in the three-wave mixing (Marker and Terchune 1965;Adair et al 1989), timeresolved interferometry (Milan et al 1977) and optical wave induced dielectric threshold (Smith et al 1975) experiments. The theoretical values of n 2 have been previously obtained within the bond orbital theory (Lines 1990) and by employing the correlation of generalized Miller's dðx; x; x; xÞ coefficient with the crystals ionicity (Go´rski et al 1996).…”
