Abstract
Commercial off-the-shelf (COTS) single-mode and multimode germanosilicate optical fibres are intended for use as part of control-command applications in the future Laser Megajoule facility. We evaluated their vulnerability to the radiative environment associated to this project by characterizing their transient radiation responses at infrared wavelengths (1064, 1310 and 1550 nm) after high dose rate exposure (> 108 Gy/s). Our results showed that these COTS fibres exhibit very different transient responses (10-9 s to 1 s after pulse) and permanent damages (times > 1s), depending on the wavelength of transmitted signal and on their compositions. Presented results could be used to define several choices to ensure the functionality of these applications for both shortest times after a shot (10-9 to 103 s) and during the whole LMJ lifetime (30 years).
