Disclosed is a method including: (i) dispersing frequency components of an input EM waveform along a first direction with each frequency component spatially extended along a second direction different from the first direction; (ii) setting an amplitude for an output portion of each of the spatially extended frequency components; and (iii) combining the output portions from the different frequency components to produce a temporally shaped output EM waveform, wherein setting the amplitude of each output portion comprises diffracting a corresponding input portion for the spatially extended frequency component along the second direction into different diffraction orders, wherein the combined output portions correspond to a common diffraction order. A system for performing the method is also disclosed.

Diffraction-based pulse shaping with a 2D optical modulator

A method for characterizing one or more properties of a sample using acoustic waveforms is disclosed, and comprises directing a sequence of at least three optical pulses to the sample to generate an acoustic response in the sample at a frequency corresponding to the pulse sequence, varying the timing of one or more of the pulses in the sequence to vary the frequency of the acoustic response in the sample, and measuring the strength of the acoustic response as a function of the varied frequency to determine information about the sample.

Characterization of materials with optically shaped acoustic waveforms

A method and apparatus for accelerating charged particles are disclosed, wherein the method comprises using at least a transverse component of a temporally and spatially shaped electromagnetic field to accelerate one or more charged particles.
