PHASE CONTROL IN ULTRASHORT PULSE LASERS BY A DEFORMABLE MIRROR IN THE PULSE STRETCHER

摘要

A direct ultrashort laser system is provided. In another aspect of the present invention, a method of measuring laser pulse phase distortions is performed without requiring an adaptive pulse shaper or interferometry. In yet another aspect of the present invention, a system, a method of operating, a control system, and a set of programmable computer software instructions perform Multiphoton Intrapulse Interference Phase Scan processes, calculations, characterization and/or correction without requiring an adaptive pulse shaper. Pulse shaping may be performed by a deformable mirror (121) in a pulse stretcher (115).
