1. A method of controlling a high-power, ultra-short pulse system containing a seed source generator generating seed pulses, a pulse stretcher, a power amplifier, a compressor, and a control system, where the pulse stretcher increases a duration of the seed pulses, the power amplifier amplifies a power of the stretched pulses, and the compressor decreases a duration of the amplified pulses, comprising:

  • controlling at least one ofa) average power output of the compressor to a specified value,b) output pulse repetition rate to a specified value, andc) output pulse energy of the compressor to a specified value; and

    control-system controlling of at least one ofd) power output of the stretcher,e) power output of the power amplifier,f) power output of a seed pulse amplifier optically located between the stretcher and the pulse picker,g) pulse picker EOM bias current to minimize pulse picker output power level at a given seed amp pump-current,h) pulse picker output pulse repetition rate,i) controlling pulse width, andj) a half-wave plate position to minimize optical power losses in the compressor.
