Abstract: | In this paper, we establish the influence of pump power on the tuning characteristics of a filterless erbium-doped fiber laser,
operating in the L band. Tunable action is achieved with the control of intra cavity loss. The explicit dependence of tunability
on the average inversion levels is brought out. The shift in the lower limit of tuning range and the non-linear dependence
of lasing wavelength on the intra cavity loss are analytically deduced using the gain spectra and experimentally interpreted
using amplified spontaneous emission spectra. Continuous tunability is achieved with the careful control of pump power.
