Homogeneous linewidth of the I11/2--I15/2 optical transition of erbium in LiNbO3:Er3+
Abstract
We work out a simple, pulsed pump-probe measurement scheme to measure the homogeneous linewidth of an atomic transition in an inhomogeneously broadened spectral line in a solid state environment. We apply the theory to the I11/2 -- I15/2 optical transition of erbium in LiNbO3:Er3+ crystal. Beside obtaining the homogeneous linewidth, we have estimated the population relaxation time as well.
