Linear laser beam

NettetLinear power density of your beam (total power divided by 1/e 2 beam diameter) Thorlabs expresses LIDT for CW lasers as a linear power density measured in W/cm. In this regime, the LIDT given as a linear power density can be applied to any beam diameter; one does not need to compute an adjusted LIDT to adjust for changes in spot size, as … NettetGaussian beams have smooth phase profiles – they are not multimode beams! In addition to the Gaussian shape of the intensity profile, a Gaussian beam has a transverse phase profile which can be described with a polynomial of at most second order:. A linear phase variation in one direction (not considered further here) describes a tilt (change of …
