We investigated second harmonic generation with ultrahigh intensity femtosecond laser pulses from a terawatt Ti: sapphire laser system. Energy conversion efficiency of about 80 % for a type I potassium dideuterium phosphate crystal was obtained with 130 fs laser pulses at an intensity as high as 192 GW/cm 2.
