IdealPhotonics' coreless terminal fiber is an optical fiber end-face device that eliminates the traditional solid fiber core through a special structural design (such as hollow or microstructure). Utilizing an air/micropore structure, it achieves low nonlinearity and high damage threshold laser transmission or sensing, suitable for special scenarios such as high-power laser output and biosensing."Air-guided light + damage resistance revolution"—by eliminating the solid fiber core (hollow/microstructure design), it completely avoids material nonlinearity and thermal effects, achieving ultra-high power (MW/cm² level) laser transmission and low-hysteresis sensing, becoming a key optical transmission terminal for extreme laser surgery and industrial processing.
