Journal ArticleDOI
Tunable random fiber laser
TL;DR: In this article, the authors presented a random fiber laser that is tunable over a broad wavelength range with uniquely flat output power and high efficiency, which outperforms traditional lasers of the same category.
Journal ArticleDOI

Dmitry V. Churkin,Sergey A. Babin,Atalla El-Taher,Paul Harper,Sergey I. Kablukov,V. Karalekas,Juan Diego Ania-Castanon,E. V. Podivilov,Sergei K. Turitsyn +8 more
TL;DR: In this paper, the authors demonstrate lasing based on a random distributed feedback due to the Raman amplified Rayleigh backscattering in different types of cavities with and without conventional point-action reflectors.
Journal ArticleDOI
20 nJ 200 fs all-fiber highly chirped dissipative soliton oscillator.
TL;DR: An alternative approach is demonstrated that enables us to increase the cavity length of the DS oscillator up to 30 m, namely, by the use of a long section of polarization-maintaining fiber in an all-fiber cavity configuration.
Journal ArticleDOI
270-km ultralong Raman fiber laser.
Sergei K. Turitsyn,Juan Diego Ania-Castanon,Juan Diego Ania-Castanon,Sergey A. Babin,V. Karalekas,Paul Harper,Dmitry V. Churkin,Sergey I. Kablukov,Atalla El-Taher,E. V. Podivilov,Vladimir Mezentsev +10 more
TL;DR: The physical mechanisms limiting optical fiber resonator length are analyzed and the longest ever laser cavity, reaching 270 km, is reported, which shows a clearly resolvable mode structure with a width of approximately 120 Hz and peak separation of approximately 380 Hz in the radio-frequency spectrum.
Journal ArticleDOI
Approaching the microjoule frontier with femtosecond laser oscillators: theory and comparison with experiment
Vladimir L. Kalashnikov,E. V. Podivilov,A. Chernykh,S. Naumov,Alma Fernandez,Roswitha Graf,Alexander Apolonski +6 more
TL;DR: In this paper, a detailed numerical analysis of heavily chirped pulses in the positive-dispersion regime (PDR) is presented on the basis of the distributed cubic-quintic generalized complex nonlinear Ginzburg-Landau equation.
