IdealPhotonics' hollow-core fiber is a special type of fiber that forms an air-guided light channel in the fiber core region through microstructure design (such as photonic bandgap or anti-resonance mechanism). This achieves ultra-low nonlinearity, high damage threshold, and mid-infrared transmission, making it suitable for cutting-edge fields such as high-power lasers and gas sensing.This "revolutionary breakthrough in air-guided light" completely eliminates the limitations of the fiber core material through photonic bandgap or anti-resonance structure, achieving near-zero nonlinearity, ultra-high power carrying capacity (MW level), and ultra-wideband transmission (ultraviolet to mid-infrared). This enables disruptive applications such as next-generation laser weapons, ultra-low latency communication, and trace gas detection.
