Analytical formulation of high-power Yb-doped double-cladding fiber laser
Mostafa Peysokhan, Esmaeil Mobini, Arash Mafi
Here a detailed formalism to achieve an analytical solution of a lossy high power Yb-doped silica fiber laser is introduced. The solutions for the lossless fiber laser is initially…
Temperature distribution inside a double-cladding optical fiber laser or amplifier
Arash Mafi
The temperature distribution inside a double-cladding optical fiber laser or amplifier is examined in detail. Traditionally, the quantum defect in the core is taken to be the main…
Group velocity distribution and short-pulse dispersion in a disordered transverse Anderson localization optical waveguide
Arash Mafi
We investigate the group velocity distribution of waveguide modes in the presence of disorder. The results are based on extensive numerical simulations of disordered optical wavegu…
Laser Cooling Characterization of Yb-Doped ZBLAN Fiber as a Platform for Radiation Balanced Lasers
Mostafa Peysokhan, Esmaeil Mobini, Arman Allahverdi +2
Recent advances in power scaling of fiber lasers are hindered by the thermal issues, which deteriorate the beam quality. Anti-Stokes fluorescence cooling has been suggested as a vi…
Heat mitigation of a core/cladding Yb-doped fiber amplifier using anti-Stokes fluorescence cooling
Esmaeil Mobini, Mostafa Peysokhan, Arash Mafi
A Core/Cladding Yb-doped fiber amplifier configuration is presented that relies on anti-Stokes fluorescence cooling for effective heat mitigation in high-power operation. In the pr…
The Impact of Spatial Correlation in Fluctuations of the Refractive Index on Rogue Wave Generation Probability
Mostafa Peysokhan, John Keeney, Arash Mafi
The presence of refractive index fluctuations in an optical medium can result in the generation of optical rogue waves. Using numerical simulations and statistical analysis, we hav…
