Spectral hole burning in dye solutions
Abstract
Using picopulses generated by a mode-locked ruby laser, we have measured the 3-8-A bandwidth of a hole burned in the 0-0 transition of cryptocyanine in methanol and demonstrated the inhomogeneous character of this transition. The population-rate equations are written for an inhomogeneous transition with two and four energy levels interacting with continuous or pulsed excitation. Using the numerical solutions of this model together with the experimental result, we determine a transverse relaxation time of 0.6 to 1.0 psec for cryptocyanine in methanol.
