Claim Text:
1. A method of scanning with a laser system, the method comprising: generating femtosecond seed pulses by an oscillator; stretching a duration of the seed pulses by a stretcher; amplifying stretched seed pulses by an amplifier into laser pulses; compensating a group delay dispersion of the laser pulses in the range of 5,000-20,000 fs outputting the laser pulses from the amplifier by an electro-optical modulator at a first repetition rate; compressing a duration of the laser pulses to the range of 1-1,000 fs by a compressor; focusing the laser pulses to a focus spot in a first target region with a scanning laser delivery system; scanning the focus spot with the first repetition rate in the first target region with the scanning laser delivery system; changing the first repetition rate to a second repetition rate with a repetition-rate controller; and scanning the focus spot with the second repetition rate in a second target region with the scanning laser delivery system.
