Good  morning,

yes I saw the reference  but he did not point out what it  was or  
function, 
This paper is more about people and events and very  little since  .......

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.

Cheers
Michael
