By using far-infrared laser spectroscopy we have studied the temperature dependence of the absorption that is due to transitions between the E¯(2E) and 2A¯(2E) levels of excited Cr3+ ions in ruby. From the temperature dependence of the linewidth we determined the inhomogeneous and the homogeneous contributions to line broadening. From the homogeneous width the lifetime of the 2A¯ level was ...
