Abstract
New wavelength fiber laser is one of the most interesting research hotspots of fiber laser science. In this paper, the 850nm band room-temperature up-conversion fluorescence of erbium doped silica optical fiber pumped by two LDs (with 800nm and 792nm emission wavelength respectively) is firstly reported, which maybe helpful for the research of 850nm fiber lasers (the first telecommunication window). The possible up-conversion mechanisms involved are discussed in terms of ground and excited-state absorption. The 800nm band absorption spectrum and 850nm wavelength band up-conversion characters are experimentally studied.
