Publication number: 20250020859Abstract: The present disclosure relates to a fiber and a laser probe assembly with a probe tip that houses the fiber. In certain aspects, the fiber includes a core, an outer cladding surrounding the core, and an end face at a proximal and/or distal end of the fiber. The core is configured to transmit a laser light beam while the core and the outer cladding are both configured to transmit an illumination light. In certain aspects, a surface area of the end face corresponding to a cross-section of at least the outer cladding is treated with a roughening or polishing process to modulate an illumination light output angle of the fiber. Using a fiber that is configured to transmit a laser light beam as well as a wide-angle illumination light allows for a more compact fiber and probe tip, allowing for medical procedures that require a narrower probe.Type: ApplicationFiled: September 27, 2024Publication date: January 16, 2025Inventors: Chenguang Diao, Ronald T.
