Abstract
Fiber burning and/or overheating of the fiber feedthrough in high-power laser modules, which may cause catastrophic and/or collateral damage, may be addressed by providing an optical fiber assembly designed to withstand overheating due to errant high power laser light that is directed toward the input core of a fiber but may be at least partially misaligned. The optical fiber may be secured within a mount having a passageway such that the end face of the optical fiber extends past an opening of the passageway to a focal plane of the incident light. The end of the optical fiber may include a section that has a reduced or absent cladding layer (e.g., etched to form a tapered cladding region) so as to reduce the amount of light captured by the cladding and/or to leak the light out quickly.
