Hollow-Core Photonic Crystal Fiber (HCPCF) technology has revolutionized Ultra-Short Pulse (USP) laser beam delivery. Industry-grade USP laser beam delivery system (BDS) modules, developed by GLOphotonics, however, display polarization fluctuations during movement. To overcome this, we've developed a BDS module maintaining constant polarization irrespective of motion. This BDS uses an inhibited-coupling HCPCF with an injected beam from a 1030 nm wavelength USP laser. Demonstrating a 97% transmission rate and stable linear polarization (34dB of polarization extinction ratio (PER)), it showed less than 3% power fluctuation and less than 1% polarization fluctuation during movement. This marks a significant advancement in BDS applications.
