Tests procedures were not specially innovative, they were rather derived from standard approved ones currently used in the space business. Which type of quantitative data would you like? Concerning the space laser, it was the first fiber laser (ie the active medium is a doped fiber) to be qualified . This was confirmed by ESA and NASA specialists at the ICSO conference. For gyroscopes, the fibers are only used to my knowledge as propagation media, the lasers used are usually diode lasers. The fiber laser can emit up to 30 mW @ 1083 nm, but operated at much lower power (# 2 mW) in present application. The qualification process was established by CNES, the french space agency, based on the mission requirements (environment conditions, duration of mission, expected availability)

infra-red laser sounds pretty common-place item, perhaps it's a McGuffin?

You have listed descirption of general tests perofrmed for one and all space qualified devices/sytems. Is it possible to include difficulty encountered and solution offered by innovative test procedure and test systems developed? Also, will you please provide with more quantitive data? e.g. your LASER is space qualifed for the first time. Do not you have fibre LASER employed in various fibre gyroscopes? Was power of LASER differnt? Also if it is for the first time, how did you derive the test and what were the parameters for it?
