Latest Patents

Among Louis Desbiens' latest patents are two groundbreaking innovations. The first, titled "Active LMA Optical Fiber and Laser System Using the Same," introduces a laser system based on nonlinear pulse compression coupled with a Large Mode Area (LMA) optical fiber. This invention is designed to amplify seed light pulses and promote the onset of nonlinear spectral broadening. The LMA optical fiber is equipped with a first section that maintains constant core and cladding diameters while supporting light pulse propagation in multiple transversal modes. This feature effectively suppresses high-order modes, thereby improving light quality. Additionally, the tapered second section of the optical fiber facilitates an adiabatic transition for the fundamental mode, enhancing the overall performance by providing excellent beam quality and high peak powers.

The second patent focuses on a "System and Method for Generating Light Pulses Based on Direct Current Modulation of a Seed Laser Diode." This innovative system allows for the generation of laser pulses through the modulation of a seed laser diode in response to a direct drive current. The process involves generating seed light pulses that possess a longer duration than the targeted pulse duration along with a spectral chirp. By utilizing a compression module with dispersion characteristics over a broad spectral range, this invention achieves the desired output light pulses with a specific duration.
