A ruby crystal rod operates as an amplifier for the radiation at λ! = 694.3 nm that coincides with the central wavelength of the rubyâs atomic transition. The quantum efficiency of the transition is close to 100 %, the spontaneous emission lifetime is t!" = 4.3 ms, and the transition cross section at the central wavelength is ð(λ!) = 2.5 x 10!!" cm!.
a) Assuming a homogeneously broadened Lorentzian transition lineshape, calculate the transition bandwidth Îv (FWHM).
