Hollow-Core Photonic Bandgap Fiber

The hollow-core photonic bandgap fiber is composed of a periodic arrangement of a two-dimensional photonic crystal, with a hollow air defect as the fiber core. Unlike the total internal reflection light-guiding mechanism of conventional fibers, the hollow-core photonic bandgap fiber uses the photonic bandgap effect to transmit light in air. In this fiber, most of the optical energy (more than 95%) is transmitted in the air core, so light transmission is less affected by absorption in the fiber material. It has excellent radiation resistance and good thermal stability, giving it advantages in harsh environments. It has low nonlinear effects and low latency, and a high damage threshold, offering clear advantages in flexible transmission of high-power and pulsed lasers. It can also serve as an efficient platform for light–matter interactions.

Ring Core Fiber

The Ring Core Fiber is a specially structured optical fiber primarily used in high-power ring-structured lasers and high-power lasers with adjustable beam modes. Traditional lasers have a single-peak Gaussian energy distribution. After coupling and beam shaping through a ring core fiber, it can form a circular laser beam with a Gaussian distribution in the core region surrounded by the ring. This effectively solves the problem of spatter during high-power laser welding.
