Abstract

The red luminescence band which is a strong broad band that occurs in natural diamonds, showing a zero phonon line at 2.145 eV and a coupling to a nearly localized phonon of 30 meV with a Huang-Rhys factor of 10, and a constant intensity up to room temperature, is shown to present tunable stimulated emission at room temperature. The stability of the band towards strong pumping conditions is discussed. Another strong luminescent band (S3) is shown to present excited state absorption.
