Abstract:
In this work, we have developed a theoretical model of a new type of pulsed fiber laser used a new generation of fiber used as an amplifying medium. This latter is called seven-core fiber. After performing a parametric study of this kind of fiber, we have successfully modeled our fiber laser cavity. Based on the simulations of the theoretical model, we have successfully demonstrated that the modelled laser can be generating two genres of nanoseconds pulses. The first one is to generate a large pulse with high energy applicate to materials processing (cutting, drilling and deep engraving of materials…). The second is to generate a pair of nanosecond pulses identical in energy for Particle Imagery Velocimetry (PIV) application. This seven-core cavity laser modelled is a good candidate to replace the other classical lasers for these applications.
