Description/Abstract

Q-switched fibre lasers have been extensively researched since the first development in 1986. Recent numerical modeling has suggested that two methods can be used to improve the energy storage per unit length within a fibre. One technique is to increase the Erbium concentration which will however, lead to clustering of Erbium ions which decreases the efficiency of the fibre through co-operative up-conversion. The method which we will present is based on using a novel fibre geometry using a large mode field area. Single-mode operation is maintained by decreasing the N.A. of the fibre.
