To calculate the coherence time ( \tau_c ) of the emitted radiation, we use the relation between coherence time and spectral width: [ \tau_c \approx \frac{1}{\Delta \nu} ] where ( \Delta \nu ) is the frequency width of the radiation. Frequency ( \nu ) is related to wavelength ( \lambda ) by: [ \nu = _______ ______ _________ ______ _______ ______.
