Optics fluence
WebWe would like to show you a description here but the site won’t allow us. 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.
