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 of Silica Glass
Esmaeil Mobini, Saeid Rostami, Mostafa Peysokhan +11
Laser cooling of a solid is achieved when a coherent laser illuminates the material in the red tail of its absorption spectrum, and the heat is carried out by anti-Stokes fluoresce…
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…
Advances in Disordered Transverse Anderson Localizing Optical Fibers
Arash Mafi, Matthew Tuggle, Cody Bassett +2
Disordered transverse Anderson localizing optical fibers have shown great promise in various applications from image transport to random lasing. Their success is due to their novel…
