ECE 455: Optical Electronics Homework 4 Due: Sept. 27, 2011 1 Doppler vs Lifetime Broadening A 2 level atom having an atomic weight of 20 AMU has radiative lifetimes of τ 1 = 10 - 8 s, τ 2 = 3 × 10 - 9 s, and energy separation E 2 - E 1 = 0.5 eV. (a) At what gas temperature is the linewidth due to the natural broadening of the transition equal
