Single-mode P2O5–F–SiO2 optical fibres with an optimised acoustic profile: Influence of the optical refractive index contrast and dopant content of the core on maximum SBS gain suppression

S. V. Tsvetkov, M. E. Likhachev Fiber Optics Research Center of the Russian Academy of Sciences Abstract: We consider optical fibres with a modified radial profile of the acoustic refractive index. The use of two-component doping of the core in a silica optical fibre makes it possible to simultaneously create different refractive index profiles for… Read More »

Numerical study of the scheme of a fibre optical parametric oscillator with two-arm synchronous pumping

Study of the influence of interaction of spectral filtering and slow saturable absorption on the formation of ultrashort pulses in fibre lasers

A. Yu. Kokhanovskiy, A. E. Perepelov, K. V. Serebrennikov Novosibirsk State University Abstract: We study the formation of ultrashort pulses in a fibre laser cavity with a slow saturable absorber and a spectral filter. It is found that in a cavity with total normal chromatic dispersion, the finite relaxation time of a saturable absorber leads… Read More »

Control of the number of solitons in a fibre laser by resonant injection of external narrow-band light

V. A. Ribenek, P. A. Itrin, D. A. Korobko, A. A. Fotiadi Ulyanovsk State University SPC “Technological Center” MIET Ioffe Institute, St. Petersburg Faculte Polytechnique, Université de Mons–Hainaut Abstract: We study mechanisms underlying the processes of production and annihilation of soliton pulses under the action of external injection. It is shown that, depending on the… Read More »

Single-frequency erbium laser with random distributed feedback implemented on phase mask inhomogeneities

M. I. Skvortsov, S. R. Abdullina, A. A. Vlasov Institute of Automation and Electrometry, Siberian Branch of Russian Academy of Sciences, Novosibirsk Abstract: We present a ∼1555.8-nm single-frequency erbium laser with random distributed feedback implemented on phase mask inhomogeneities upon writing a single highly reflective fibre Bragg grating. The spectrum of such a grating contains… Read More »
