Latest Patents

Sean M Courtney 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. In some embodiments, thermal effects drive the MI process, and the invention offers various options for mitigating these thermal effects. The hybrid fiber design features a smaller core in the initial length, where thermal loads are highest, followed by a larger-core fiber. This configuration helps maintain 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 delivering performance comparable to conventional fibers, minimizing fiber nonlinearities such as Stimulated Brillouin Scattering (SBS). Notably, the hybrid fiber can output a signal beam with at least 1 kW of power.
