Latest Patents

Khushvinder S Brar holds a patent for a "Fiber amplifier system for suppression of modal instabilities and method." This invention provides an apparatus and method for suppressing modal instabilities (MI) in fiber-amplifier systems. The patent outlines various embodiments where thermal effects drive the MI process. In some cases, the invention offers multiple options for mitigating these thermal effects. Notably, it introduces a hybrid fiber design with a smaller core in the initial length, where thermal loads are highest, followed by a larger-core fiber. This design aims to keep the core heat-per-unit-length of the second section below a critical value for the onset of MI. The hybrid fiber avoids modal instabilities while maintaining performance comparable to conventional fibers, particularly in minimizing fiber nonlinearities such as Stimulated Brillouin Scattering (SBS). The hybrid fiber can output a signal beam with at least 1 kW of power.
