The reference [145] at the end of the sentence that mentions sapphire oscillators also discusses a hybrid photonic-microwave oscillator that incorporates a room-temperature sapphire oscillator so I think he tried to cover both subjects with that single reference. The paper has a misleading title. It suggests that it is a history of the last 50 years, when it is about events roughly 50 years ago. The abstract makes this clear though. So I didn't really expect to read much about developments past 1970.
