Disclosed in the present invention is a beam coherence eliminating element. The optical medium material of the element comprises microcrystalline glass, wherein microcrystalline particles therein have a size of 0.1-1000 nm and are distributed randomly. As the crystals in the microcrystalline glass can change the phase of light beams, the microcrystalline glass can change the phase of the light beams randomly, thereby eliminating the coherence of the beams. The crystal size of the microcrystalline glass is small, and thus does not affect the transmission efficiency of light beams. The element of the present invention has a simple structure and is convenient to use, and can be added in the process of beam transmission to easily eliminate beam coherence.

A fully programmable laser field shaping apparatus that can configure a beam of laser pulses in both shape and time to generate laser pulses with varying spatio-temporal profiles for adaptive nonlinear optical propagation. The laser field shaping scheme in accordance with the present invention, Adaptive Spatio-Temporal Optical Pulse Shaper (A-STOPS), utilizes dispersive elements and a programmable spatial varying optical element (e.g. deformable mirror, spatial light modulator, etc.) to impose spatial variations on each frequency component of a laser pulse. Each frequency component maps directly to a temporal slice within a chirped laser pulse. The result is the ability to generate complex spatio-temporal variation on a laser pulse with wide ranging applications in linear and nonlinear optics.
