Laser-induced anti-Stokes fluorescence cooling of ytterbium-doped silica glass by more than 6 Kelvin
Mostafa Peysokhan, Saeid Rostami, Esmaeil Mobini +12
Laser cooling of a solid is achieved when a coherent laser illuminates the material, and the heat is extracted by resulting anti-Stokes fluorescence. Over the past year, net solid-…
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…
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…
