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...
