Transcribed image text: Consider a three-level laser. It obeys the rate equations: dN_3/dt = gamma_ 31 I_p N_1 - N_3/tau_32 dN_2/dt = gamma_21 I_s N_1 - gamma I_s N_2 + N_3/tau_32 - N_2/tau_21 dN_1/dt = -gamma_31 I_p N_1 - gamma_21 I_s N_1 + gamma_21 I_s N_2 + N_2/tau_21 Sketch a diagram showing the meaning of the terms in the above equation and what physical processes they correspond to.
