1. A system, comprising:

  • a fiber-based source of ultrashort laser pulses, said fiber-based source comprising at least one fiber amplifier, wherein said fiber-based source comprises an adjustable grating compressor to compress optical pulses, said grating compressor operatively connected to said controller to align said grating compressor;

    a controller to control said fiber-based source; and

    a beam manipulator to monitor one or more pulse characteristics of said laser pulses and to generate feedback data for said controller,wherein said pulse characteristics comprise an output power, a pulse energy, a pulse width, a wavelength, a repetition rate, a polarization, a temporal delay, a temporal phase, a spatial phase, or a combination thereof,wherein said controller receives signals representative of said one or more pulse characteristics and generates control signals to vary at least one of said pulse characteristics, said controller being networked to at least one computing means via a physical link and/or wireless link.
