Paper Abstract

Potoconductive properties and relaxation of free charges in high pure natural and CVD diamond were investigated and compared in the spectral range 1 .5-30 eV using a variety of pulsed laser sources including harmonics of radiation of 50 fs Ti:Sa laser. The resulting spectra were compared to experimental data in surface photoemission and speculated in terms of free carriers multiplication, effect of the surface layer, saturation of absorption, trapping of carriers and the following charge transfer between deep electron centers.
