hermite_gaussian

hermite_gaussian_phase はエルミート・ガウシアン (HG) ビーム を生成する.

laguerre_gaussian_phase と同様に, 振幅は hermite_gaussian_intensity で変更する.

API

Rust

let option = HermiteGaussianOption {
    m: 1,
    n: 0,
    waist: 10.0 * mm,
};
hermite_gaussian_phase(&geometry, target, axis, x_dir, option, wavelength, &mut phases);
hermite_gaussian_intensity(&geometry, target, axis, x_dir, option, wavelength, &mut intensities);

Python

option = HermiteGaussianOption(m=1, n=0, waist=10.0)
hermite_gaussian_phase(geometry, target, axis, x_dir, option, wavelength, phases)
hermite_gaussian_intensity(geometry, target, axis, x_dir, option, wavelength, intensities)

C#

var option = new HermiteGaussianOption(m: 1, n: 0, waist: 10.0f * mm);
Pattern.HermiteGaussianPhase(geometry, target, axis, xDir, option, wavelength, phases);
Pattern.HermiteGaussianIntensity(geometry, target, axis, xDir, option, wavelength, intensities);
