Stable ultrashort pulses have applications in ultrafast laser spectroscopy, biology, medicine and fibre optic communication. Fiber lasers are capable of producing femtosecond duration pulses at 1.55 μm. In the present paper we report our simulations on effect of higher order dispersion parameters on pulse generation and propagation in figure of eight laser.

Theoretical simulations on femtosecond pulse generation in infrared region by a fiber laser

Proceedings of SPIE - The International Society for Optical Engineering

Theoretical simulations have been carried out to achieve ultrafast pulse generation in an all-fiber laser known as a figure-of-eight laser (F8L). It is observed that the higher order nonlinear dispersions play a vital role in determining the stability of the output pulse on a femtosecond (fs) time scale. Best fit parameters for F8L to generate pulses as short as 420 fs are reported here.
