Use of extended laser plasma for generation of high-order harmonics of picosecond duration

We report the results of experimental investigations on the generation of picosecond radiation harmonics in extended laser plasma produced on the surface of different metal targets. The effect of plasma length, heating pulse duration and delay between the heating and transformable pulses on the effi...

Zusammenfassung:We report the results of experimental investigations on the generation of picosecond radiation harmonics in extended laser plasma produced on the surface of different metal targets. The effect of plasma length, heating pulse duration and delay between the heating and transformable pulses on the efficiency of conversion to higher harmonics is studied. The radiation conversion to a short-wavelength (down to , 21st harmonic) range in extended plasma of several metals is demonstrated.
