Multi-physic simulation in the laser sources

ASE (Amplified Stimulated Emission)

In excited amplifier media, photons are emitted very weakly and spontaneously. These photons are then amplified by the medium to significant levels.

multiphysics; multiphysique

A study that simultaneously takes into account physical effects and their dependencies, whereas they are usually treated independently: thermal effect, optical deflection and laser-matter interaction, for example.

thermomechanics; thermo mechanical

Includes effects related to material heating: temperature rise, material expansion and induced mechanical stress.

Zernike coefficients; Zernike coefficients

Coefficients used to model wave surfaces as two-variable polynomials. Each coefficient corresponds to a particular...
