Nd:YLF pumped grating-feedback Er3+:Yb3+ co-doped silica fibre laser operating at 1.49 micron

Kringlebotn, J.T., Archambault, J.L., Reekie, L., Laming, R.I. and Payne, D.N. (1996) Nd:YLF pumped grating-feedback Er3+:Yb3+ co-doped silica fibre laser operating at 1.49 micron Optical Fiber Technology, 2, (1), pp. 69-74. (doi:10.1006/ofte.1996.0006).

Record type: Article


We demonstrate for the first time a 1.49µm Er3+:Yb3+ co-doped silica fiber laser with fiber Bragg grating feedback, pumped with a diode-pumped Nd:YLF laser at 1.047µm, which can be used for remote pumping of EDFAs. We examine both the potential and limitations of this laser as a high power source and point out how an efficient, high power laser could be realized. The maximum demonstrated output power, 21mW, was limited by the cavity losses, by the strong ASE at the peak gain wavelength 1.535µm, and by a "bottleneck effect" in the energy transfer between ytterbium and erbium with a corresponding reduced pump absorption at higher pump powers. By overcoming these limitations an output power in excess of 500mW with 1W of pump power is predicted.
