  • Achieving gaussian outputs from large-mode-area-higher-order mode fibers
    Patent number: 7672552
    Abstract: A mode conversion technique to convert higher-order-mode into a nearly fundamental Gaussian shape by using a beam expander is developed and is particularly useful in high-power lasers and amplifiers. By using a beam expander between a transmitted fiber and a conventional mode conversion system, the strict lateral tolerance requirement can be overcome with high conversion efficiency.
    Type: Grant
