Abstract: We have observed electric pulses generated in sillenite crystals (Bi 12 SiO 20 and Bi 12 TiO 20 ) by 100 fs laser pulses at the wavelength of 400 nm. Direction of the induced current depends on the polarization state of the laser pulse. High photogalvanic response and its linear dependency on light power density in a wide range (up to 45 GW/cm 2 ) makes sillenite crystals promising materials for ultra-fast optoelectronics devices.
Keywords: photogalvanic effect, ultra-short laser pulses, sillenites
