VARIABLE PULSE STRETCHING LENGTH BY VARIABLE BEAMSPLITTER REFLECTIVITY

摘要

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