VARIABLE PULSE STRETCHING LENGTH BY VARIABLE BEAMSPLITTER REFLECTIVITY

摘要

A laser pulse stretching unit (100) is described herein which is configured to change the reflectivity of one or more beam splitters (102) located therein to change a temporal profile of an output beam (116) without needing to adjust a length of any delay lines (104). In addition, a method is described herein for using the laser pulse stretching unit (100) to change the reflectivity of one or more beam splitters (102) located therein to change a temporal profile of an output beam (116) without needing to adjust a length of any delay lines (104).
