Abstract
A laser system capable of phase and/or amplitude manipulation of the output pulses is provided. In another aspect, a laser system includes a self-referenced pulse characterization method. A further aspect uses spectral amplitude modulation to isolate spectral bands by scanning one or more transmission slits or openings, and measuring and/or calculating the first derivative of a phase (group delay) across an entire spectrum. A single-beam pulse shaper-based technique for spectrometer-free measurement and compensation of laser pulse phase distortions is also provided in an additional aspect.
