Fivecharacteristics of a laser

(i) Monochromaticity: A laser beam is more or less in single wavelength. i.e., the line width of laser beams are extremely narrow. The wavelengths spread of conventional light sources is usually 1 in 106, whereas in case of laser light it will be 1 in 1015. i.e., if the frequency of radiation is 1015 Hz, then the width of line will be 1 Hz. So, laser radiation is said to be highly monochromatic. The degree of non-monochrotmaticity has been expressed as where dλ or dν is the variation in wavelength or variation in frequency of radiation. ...
