The. 002 nm bandwidth of the lasing medium is well over 10, 000 times narrower than the spectral width of a light-emitting diode ( whose spectrum is shown: Image: Red-YellowGreen-Blue LED spectra. png | here for comparison ), with the bandwidth of a single longitudinal mode being much narrower still.
