Pump excited state absorption in Er3+ doped optical fibres.
11 November 1989
Ground and excited state absorption coefficients in the wavelength range 420–850 nm of Er3+ doped optical fibres have been measured for various composition silica and fluorozirconate based fibres. Detailed results are presented for features near 650 nm and 800 nm. Excited state absorption near 800 nm is significant for all the fibres studied. Other possible pump wavelengths are discussed.
