The NV centers formed in diamond by the irradiation of ion or electron beam has been studied. Recently, the formation of NV centers by focused femtosecond laser irradiation and the successive heat treatment has been reported. In our study, we aim to reveal the details of graphitization and NV center formation behavior with respect to the laser irradiation condition.
