Amplification and formation of femtosecond laser single pulses upon the high-current electron beam pumping of Ti:Al^sub 2^O3 crystals

Features of the high-power nanosecond X-ray and electronic excitation of Ti:Al2O3 crystals are investigated. It is shown that the coefficient for the single-pass amplification of femtosecond laser emission reaches 11 upon the high-current nanosecond electron beam pumping of Ti:Al2O3 crystals, along...

Description
Summary:Features of the high-power nanosecond X-ray and electronic excitation of Ti:Al2O3 crystals are investigated. It is shown that the coefficient for the single-pass amplification of femtosecond laser emission reaches 11 upon the high-current nanosecond electron beam pumping of Ti:Al2O3 crystals, along with the synchronous emission of a femtosecond laser single pulse under the action of the induced accompanying hypersonic wave.
