Abstract
A technique for controlling the effects generated by the interaction of a plurality of laser pulses with a medium by selecting or varying the successive pulse parameters comprising: generating a plurality of laser pulses interacting with a medium; and selecting or varying the properties/parameters characterizing said laser pulses to control the effects resulting from the interaction among said plurality of laser pulses and said medium.

A method for controlling the effects generated by the interaction of a plurality of laser pulses with a medium by selecting or varying the successive pulse parameters comprising:
- generating a plurality of laser pulses interacting with a medium;
- and selecting or varying the properties/parameters characterizing said laser pulses to control the effects resulting from the interaction among said plurality of laser pulses and said medium.
A method for controlling the effects generated by the interaction of a plurality of laser pulses with a medium by selecting or varying the successive pulse parameters comprising:
- generating a plurality of laser pulses interacting with a medium;
- and selecting or varying the properties/parameters characterizing said laser pulses to control the effects resulting from the interaction among said plurality of laser pulses and said medium, in which the pulse duration of the pulses is controlled through phase matching of the successive pulses in order to obtain the shortest “few-cycle” pulses available, and hence the broadest spectrum of the component wavelengths.
A method for controlling the effects generated by the interaction of a plurality of laser pulses with a medium by selecting or varying the successive pulse parameters comprising:
- generating a plurality of laser pulses interacting with a medium;
- and selecting or varying the properties/parameters characterizing said laser pulses to control the effects resulting from the interaction among said plurality of laser pulses and said medium, wherein the pulse parameters are tuned, including tuning of wavelength and frequency, with super-position of differing pulse trains, in order to optimize material interactions, including surface treatments and ablation.
