Abstract

Bulk SrTiO3 doped by 40 keV Cr+ ions and substrate temperature Timp = 600°C is studied. This sample exhibits supercontinuum generation by amplified femtosecond laser pulses (λ = 800 nm; repetition rate, 3 kHz; pulse duration, 150 fs; pulse energy 4 µJ), recorded by a monochromator with a PMT. The blue edges of the supercontinuum spectra differ, depending on the location of the focused laser beam spot on the sample.
