Brightness property of laser

Web10.2 Characteristics of laser radiation. Laser radiation has the following important characteristics over ordinary light source. They are: i) monochromaticity, ii) directionality, iii) coherence and iv) brightness. (i) Monochromaticity: A laser beam is more or less in single wavelength. i.e., the line width of laser beams are extremely narrow. WebFluorescence output per fluorophore (“brightness”) is proportional to the product of the extinction coefficient (at the relevant excitation wavelength) and the fluorescence quantum yield. ...
