WebIn general physics, the fluence is defined as the time-integrated flux of some radiation or particle stream. Specifically in optics, the fluence F e.g. of a laser pulse is the optical … Webcharged particles, vanishes when the flux (or fluence) is constant (˚uf ·˜˚ = 0) r. This condition of uniform flux (or fluence), is also known as CPE. Since the right-hand side of the equation is proportional to the mass density, it may be cancelled out and the solution of the transport equation is, therefore, independent of mass density.
