Line shape function laser
NettetWe could measure the lineshape function for a particular optical transition by observing the spontaneous emission spectrum of the light. The total optical power emitted by … NettetLasers emit light over a range of wavelengths described by the laser line shape function.[1{3] For a HeNe laser operating under normal conditions, the main source of laser line shape broadening is Doppler broadening in the lasing medium, resulting in a Gaussian gain pro le (see Fig. 1). The laser does not emit a continuous spectrum
