Analytical formulation of a high-power Yb-doped radiation balanced fiber laser
Mostafa Peysokhan, Brian Topper, Esmaeil Mobini +1
We present an analytical solution for a radiation balanced fiber laser, in which no net heat is generated during lasing operation due to cooling by anti-Stokes fluorescence. The re…
Laser Cooling of a Yb Doped Silica Fiber by 18 Kelvin From Room Temperature
Brian Topper, Mostafa Peysokhan, Alexander R. Albrecht +10
A ytterbium doped silica optical fiber has been cooled by 18.4K below ambient temperature by pumping with 20W of 1035nm light in vacuum. In air, cooling by 3.6K below ambient was o…
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…
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…
Spectroscopic Investigation of Yb-doped Silica Glass for Solid-State Optical Refrigeration
Esmaeil Mobini, Mostafa Peysokhan, Behnam Abaie +2
We have argued that a high-purity Yb-doped silica glass can potentially be cooled via anti-Stokes fluorescence optical refrigeration. This conclusion is reached by showing, using r…
A novel method for measuring the resonant absorption coefficient of rare-earth-doped optical fibers
Mostafa Peysokhan, Esmaeil Mobini, Behnam Abaie +1
A non-destructive method for measuring the resonant absorption coefficient of rare-earth-doped optical fibers is introduced. It can be applied to a broad range of fiber designs and…
