The role of 850-nm fluorescence, amplification, and laser emission in ZBLAN:Er³⁺ optical fiber was first investigated by Whitley et al. [1,2] and Allain et al. [3]. In the case of a green upconversion fiber laser at 544 nm, the 850-nm fluorescence is a parasitic component, so it should be minimized or eliminated. Two pumping wavelengths are usually applied to excite the green upconversion laser: 970 nm or 800 nm. It has been already observed that 800-nm pumping favours, to some extend, the 850-parasitic emission, and the 970-nm one makes this emission negligible [1–3]. We have studied the role of 800-nm pumping in more detail and observed a dependence of the pumping wavelength ~800 nm on the intensity of the 850-nm parasitic fluorescence.
