Title: Optical pulse combiner comprising diffractive optical elements

Abstract

This disclosure provides systems, methods, and apparatus related to optical systems. In one aspect, an optical system includes a plurality of optical sources, a first diffractive optical element, and a second diffractive optical element. The plurality of optical sources generates a plurality of pulsed beams that is less than about 1 picosecond in duration. The first diffractive optical element receives and diffracts the plurality of pulsed beams. The second diffractive optical element receives the diffracted plurality of pulsed beams and generates a combined pulsed beam.
