A system and method for reducing peak power of a laser pulse and reducing
speckle contrast of a single pulse comprises a plurality of elements
oriented to split and delay a pulse or pulses transmitted from a light
emitting device. The design provides the ability to divide the pulse into
multiple pulses by delaying the components relative to one another.
Reduction of speckle contrast entails using the same or similar
components to the power reduction design, reoriented to orient received
energy wherein angles between the optical paths are altered such that the
split or divided light energy components strike the target at different
angles or different positions. An alternate embodiment for reducing
speckle contrast is disclosed wherein a single pulse is passed in an
angular orientation through a grating to create a delayed portion of the
pulse relative to the leading edge of the pulse.
