Abstract
According to news reporting originating from Washington, D.C., by NewsRx journalists, a patent application by the inventors Biafore, Robert David (Richmond Hill, CA); Prajapati, Sheelkumar Areshkumar (North York, CA); Yuan, Xing (Markham, CA); Zhang, Mingfeng (Scarborough, CA), filed on August 5, 2022, was made available online on February 8, 2024. No assignee for this patent application has been made. Reporters obtained the following quote from the background information supplied by the inventors: "A beam delivery system is a device for transmitting a laser beam from its source to a laser head that projects the beam to a workpiece. Optical fibers are generally a preferred option for beam delivery because of their flexibility. This flexibility is especially beneficial for applications where the laser head needs to move. However, optical fibers cannot transmit a laser beam with a wavelength longer than 2600 nanometers due to high absorption rate of fibers. CO2 laser is an example of laser that cannot be delivered by optical fibers. Instead, CO2 laser is generally delivered by reflective mirrors that are often encapsulated in tubes.
