LASYthon April 2025

[MaxThevenet]

General

• Add grid copy constructor.
• Add chromatic optics. @cristina
• clean up changelog to clarify non-backward-compatible changes and remove (or make less prominent) the pre-commit-CI PRs ??
• Improve show function for more exhaustive view of laser pulse (also working for CW and plane wave). @delaossa?
• Allow FromArrayProfile to take in a pulse in x,y,omega space, and update FromInsightProfile accordingly. @Paaaaarth
• Badges. @Paaaaarth
• LASY on GPU. @Paaaaarth
• Grating optics element @cora.

Propagators

We will start from #395 to structure the implementation of new propagators. Each propagator should be implemented as a new class that works for both geometries (probably take dim as an argument of the init function).

• Skeleton code with enough flexibility
• Populate Propagator, SingleFFTPropagator, DoubleFFTPropagator with common elements (x,y,omega interpolator? FFT helpers? Grid size check/adjustments?)
• Implement Collins propagator @em-archer
• Implement Fresnel SingleFFTPropagator @rob-shalloo
• Implement split-step propagator @TimoEichner
• Implement DoubleFFTPropagators: Angular Spectrum, Kirchhoff? Rayleigh-Sommerfeld?
• Export Axiprop's propagators to the new structure (optionally expose more propagators) @hightower8083
