-based hollow core anti-resonant Photonic Crystal Fiber (PCF) package of high-power Laser optical fiber transmission system, high-energy picosecond or femtosecond pulse Laser can be limited in the fiber within the very small hollow core structure, with excellent M² Beam Quality for transmission. Compared with the ultra-fast Laser commonly used space optical transmission mode, the system greatly simplifies the transmission system operation and structure, can meet the user's flexible processing needs, and has the bearing power high, low loss, low distortion, near single-mode transmission characteristics.
