“…It is estimated that at RT, lifetime would be of the order of 1 s or less. This fast relaxation time, compared to RE ions ( 1 ms) has been implemented as a fiberized saturable absorber in a passively Q-switched all-fiber laser [54].…”

We present some of our research activities dedicated to doped silica-based optical fibers, aiming at understanding the spectral properties of luminescent ions, such as rare-earth and transition metal elements. The influence of the local environment on dopants is extensively studied: energy transfer mechanisms between rare-earth ions, control of the valence state of Chromium ions, effect of the local phonon energy on Thulium ions emission efficiency and broadening of Erbium ions emission induced by oxide nanoparticles. Knowledge of these effects is essential for photonics applications. keywords optical fiber, silica, spectroscopy, rare-earths, transition metals, energy transfer, valence state, phonon energy, local environment

We have adapted the point model for the study of an all-fiber laser doped with Nd 3 + and Q-switched by a saturable fiber absorber doped with Cr 4 + . Calculations of the output power of the 1084 nm laser are considered as a function of the pump power supplied by a 790 nm laser diode. The analysis of the simulation results reveals the existence of pulsed, sinusoidal, and dc operating regimes. C 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).

“…Among various Q-switching methods, the passive Q-switching technique by means of saturable absorbers is particularly interesting from both a fundamental and a technological point of view. Up to now, Cr 4+ -doped [7], Sm-doped [8], and Tm 3+ -Yb 3+ co-doped [9] fibers have been developed as fiber saturable absorbers in fiber laser systems in the range of 1.0-1.1 m.…”

An analytical model has been developed to minimize the effective mode area in a saturable absorber for an external-cavity passively Q-switched fiber laser. Under the condition of minimum effective mode size inside the saturable absorber, the analytical expressions for two key parameters of an optimum system have been derived. One parameter is the optimum focal position that is analytically derived to be a function of the thickness and initial transmission of the saturable absorber. The other parameter is the optimum magnification of the re-imaging optics that is analytically derived to be in terms of the numerical aperture and core radius of the laser fiber as well as the thickness and initial transmission of the saturable absorber. The present model provides a straightforward procedure to adopt a focusing system for the output performance. A diode-pumped ytterbium-doped fiber lasers with a Cr:YAG crystal as a saturable absorber is considered to illustrate the utility of the present model
