Mysterious frequency combs in erbium-doped fiber lasers at low temperatures
Alexander Bekker, Gefen Levite, Baruch Fischer
We report on the observation of puzzling nonuniform, but ordered, frequency combs in erbium-doped fiber lasers at low temperatures, between 3 K and 14 K. At ~14 K the combs disappe…
Thermalization of one-dimensional photon gas and thermal lasers in erbium-doped fibers
Rafi Weill, Alexander Bekker, Boris Levit +2
We demonstrate thermalization and Bose-Einstein (BE) distribution of photons in standard erbium-doped fibers (edf) in a broad spectral range up to ~200nm at the 1550nm wavelength r…
Multi-dimensional laser mode combs (mode hyper-combs)
Alon Schwartz, Baruch Fischer
Laser frequency combs, as most lasers, are one-dimensional. Here we present a realization of d-dimensional laser mode lattices (mode hyper-combs) with unique properties. They are c…
When does lasing become a condensation phenomenon?
Baruch Fischer, Rafi Weill
We present a generic classical light condensation (LC) phenomenon in linear photonic mode systems, such as cw laser cavities, in a noisy environment (spontaneous emission, etc.), b…
Spectral Sidebands and Multi-Pulse Formation in Passively Mode Locked Lasers
Rafi Weill, Alexander Bekker, Vladimir Smulakovsky +2
Pulse formation in passively mode locked lasers is often accompanied with dispersive waves that form of spectral sidebands due to spatial inhomogoneities in the laser cavity. Here…
The Distribution Route from Ancestors to Descendants
Baruch Fischer, Moshe Zakai
We add here compared to our former arXiv version an explicit expression for the descendant ratio along the generations The equation that is added here appeared in the Hebrew versio…
