Advances in the amplification and manipulation of ultrashort laser pulses hasled to revolutions in several areas. Examples include chirped pulseamplification for generating high peak-power lasers, power-scalableamplification techniques, pulse shaping via modulation of spatially-dispersedlaser pulses, and efficient frequency-mixing in quasi-phase-matched nonlinearcrystals to access new spectral regions. In this work, we introduce anddemonstrate a new platform for nonlinear optics which has the potential tocombine all of these separate functionalities (pulse amplification, frequencytransfer, and pulse shaping) into a single monolithic device. Moreover, ourapproach simultaneously offers solutions to the performance-limiting issues inthe conventionally-used techniques, and supports scaling in power and bandwidthof the laser source. The approach is based on two-dimensional patterning ofquasi-phase-matching gratings combined with optical parametric interactionsinvolving spatially dispersed laser pulses. Our proof of principle experimentdemonstrates this new paradigm via mid-infrared optical parametric chirpedpulse amplification of few-cycle pulses.
