Abstract
In a picosecond excite‐and‐probe absorption measurement, a 527‐nm picosecond pulse excites the 4T2 state of the Cr3+ ion in ruby and a 3.4‐μm picosecond probe pulse monitors the growth and decay of population in the 2E state as a function of pump‐probe delay. From the growth of population in the metastable 2E state, an upper limit of 7 ps for the nonradiative lifetime of the 4T2 state is determined.Keywords
