Abstract

In this paper we analyze the threshold violet and ultra-violet laser operation in Nd³⁺ doped ZBLAN fibers, using relatively fast and accurate method, based on measured spectroscopic parameters like fluorescence lifetimes and emissiod/absorption cross-sections spectra. Our approach, which is based on energy theorem and threshold field approximation, extends the model presented in [1] by taking into account the longitudinal and transverse field distribution of the fiber laser mode. Specifically, in this work we compare the efficiency of two possible laser pumping schemes: direct and two-photon excitation. The problem of laser resonator optimization is discussed by providing the analytical formulas for small signal gain in active fiber medium as a function of structure parameters i.e. the cavity geometry, distributed losses of the active medium, output power level and the mirror reflectivity. As the result of the carried-out optimizations we can determine the conditions for obtaining short-wavelength lasing in Nd:ZBLAN fiber laser with minimal threshold and maximal output power level.
