Active Media

Gain and amplification components.

Overview

The Active Media module provides trainable saturable gain sheets for laser amplifiers.

Quick Example

using FluxOptics, CairoMakie

λ = 1.064
speckle_dist = generate_speckle((256, 256), (1.0, 1.0), λ, 0.05)
u = ScalarField(speckle_dist, (1.0, 1.0), λ)

# Pumped region (Gaussian)
gain_pumped = GainSheet(u, 1.5, 1.0, (x, y) -> exp(-((x-50)^2 + y^2)/50^2))

source = ScalarSource(u)

# Use in system
system = source |> gain_pumped

u_out = system().out

visualize((u, u_out), (intensity, complex); colormap=(:inferno, :dark), height=120)
Example block output
