Observation of optical gain from NV− center in diamond by femtosecond transient absorption

Single crystal diamonds with strong NV− luminescence were prepared by high-pressure high-temperature method and followed by electron irradiation and annealing process. The stimulated emission and gain characteristics of NV− diamond in femtosecond time scale are also studied using the transient absor...
