Impact of composition modification of oxyorthosilicates single crystals on pulsed laser radiation self-action effect manifestation
For the first time the diagnostics of oxyorthosilicates single crystals based on self-action of picosecond range laser pulses at 1064 nm has been performed. It was found high sensitivity of the photoinduced refractive index variation to the substitution of the Lu atoms by Gd as well as the admixture of Ce to the LSO/LGSO crystalline matrix. The effect could be attributed to the different electron detrapping-recombination processes efficiencies due to the oxygen vacancies excitation.
