Abstract

Q-switched erbium doped fiber lasers offer a simple and robust way for the generation of high energy nanosecond pulses at wavelengths about 1550 nm, which are suitable for a large number of applications. Nevertheless, pulse peak power is limited taking into account the specific characteristics of the fiber lasers such as their long cavity length and the low level of pump power with the core pumping technique. Recently, we have demonstrated highly efficient coherent combining of radiations emitted by two amplifying fibers inside a common cavity in the continuous wave regime. The principle of this method is based on the self-organization property of lasers ensuring operation on modes of lowest losses in a Mach-Zehnder interferometer resonator geometry. We have shown that the output power level is twice the one of a unique laser. We report the power rising of an actively Q-switched erbium doped fiber laser by using two coupled cavities with amplifying fibers in an interferometer configuration. This study shows that the pulse peak power obtained is 1.7 higher than in a case of a unique laser. This concept brings some novel perspectives for scaling the output peak power of monomode Q-switched fiber lasers.
