摘要

Method conversion of ultrashort laser pulses to the second harmonic by passing a laser pulse through a nonlinear crystal transducer, characterized in that before being fed to the crystal laser pulse chirped frequency and the second harmonic of the resulting pulse is compressed in time, the pulse width of the second harmonic τ2ω determined from the relationship ! ,! where τ - duration of the pulse at the fundamental frequency, and τsh - the duration of the chirped pulse.
