Optics fluence
WebJul 12, 2024 · 8.2: High Fluence Effects. To avoid Q-switched mode-locking caused by a semiconductor saturable absorber, the absorber very often is operated far above the saturation fluence or enters this regime during Q-switched operation. Therefore it is also important to understand the nonlinear optical processes occuring at high excitation levels … 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 … where the beam radius w is the distance from the beam axis where the optical …

Webfactor in damaging the optic is peak power density (PPD) W/cm2 (peak fluence per unit time) which is the quantity being assessed in pulsed laser damage threshold testing4,5. The ISO definition of laser damage is: "Any permanent laser-radiation-induced change in characteristics of either the substrate or the coating". The ISO standards rule on WebThe key parameters for a saturable absorber are its wavelength range (where in the electromagnetic spectrum it absorbs), its dynamic response (how fast it recovers), and its saturation intensity and fluence (at what intensity or pulse energy it saturates). Saturable absorber materials are useful in laser cavities.
