Abstract
Section titled “Abstract”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 absorption technique. Stimulated emission was observed at 660-800 nm, with an optical gain displayed in the range of 680-725 nm. Further test revealed that the optical gain lifetime is 3.5 ns and the gain coefficient is 0.16 cm−1, demonstrating the potential realization of color center lasers.
