Abstract :
Many potential applications requiring high-power transmission at short wavelengths are hampered by colour-centre formation. It is perhaps not generally realised that the induced absorption continues to evolve after the laser light is blocked. This relaxation phenomenon is studied in germanosilicate fibres at blue/green wavelengths and fitted to a three-rate analytical model.
