SWITCHABLE LASER AND FIBER BASED LAMPHOUSE FOR OPTIMAL POWER OUTPUT IN DIFFERENT WAVELENGTH BANDS AND PIXEL SIZES

摘要

A system and method for providing a laser sustained plasma light source is disclosed. Unlike conventional laser-persistent plasma light sources, which utilize one fiber size and one wavelength combination in the lamp house to generate light for different wavelength ranges and pixel sizes, the optimal power output at different wavelengths and pixel sizes A switchable fiber size and wavelength combination is provided. More specifically, a switchable fiber configuration is provided in which larger fibers with higher pump power are used for larger pixel sizes and smaller fibers are used for smaller pixel sizes and shorter wavelength ranges. Additionally and / or alternatively, the pump wavelength near the absolute peak of the gas fill is used for a larger pixel size and the pump wavelength away from the gas fullness absolute peak is used for a smaller pixel size A pumping scheme is provided.
