#Intensity of laser light equation how to

In science, an inverse-square law is any scientific law stating that the observed 'intensity' of a specified physical quantity is inversely proportional to the square of the distance from the source of that physical quantity. Thus the field intensity is inversely proportional to the square of the distance from the source. The density of flux lines is inversely proportional to the square of the distance from the source because the surface area of a sphere increases with the square of the radius. The total number of flux lines depends on the strength of the light source and is constant with increasing distance, where a greater density of flux lines (lines per unit area) means a stronger energy field. The lines represent the flux emanating from the sources and fluxes. 30, 1843–1845 (2005).S represents the light source, while r represents the measured points. 5-Hz, >250-mJ optical parametric chirped-pulse amplifier at 1053 nm.
