Abstract

Long-lived trapped electrons are generated in titanium oxide gels in a convergent part of a loosely focused beam from a millijoule, femtosecond Ti:Sapphire laser. The appearance of trapped electrons is accompanied by the generation of the white supercontinuum. Considering the relevant physical mechanisms of trapped electron accumulation, we show that two-photon interband transitions with participation of photons at the fundamental frequency and from the blue part of the supercontinuum explain the experimental findings.

Dependence of the initial rate of the gel absorption growth R at 800 nm in a 0.5 mm cell (triangles) on laser intensity at the entrance to the cell (a) when changing the laser pulse energy at fixed pulse duration tp = 50 fs, (b) when changing the pulse duration at fixed pulse energy Ep = 0.9 mJ. Thickness of the quartz window is 1.5 mm. Other irradiation parameters are: dbeam = 1.25 mm, and f = 100 Hz. Circles indicate values of normalized products, εmax ×ε650 /tp , of spectral densities of the output radiation (see Fig. 3) at the wavelengths of the spectral maximum and at λ=650 nm.
