Abstract:
We discuss the use of second harmonic generation (SHG) and subsequent temporal compression to increase the peak power and improve the temporal contrast ratio of pulses at the output of petawatt and multi-petawatt laser systems. Two ways to apply SHG are considered: directly to ultra-short pulses with central wavelengths of 910 nm and 800 nm, as well as to (sub)-picosecond pulses of neodymium lasers with energies up to 1 kJ. The second way is a new approach to producing sources of ultrahigh-power laser pulses of ultra-short duration in the visible wavelength range and may be used in all modern projects aimed at generating extreme light.
