Abstract

A compact high-brightness blue laser is designed and developed. Through BPP theory and ZEMAX simulation, 18pcs TO-packaged 5W blue lasers are coupled into a 113μm core diameter 0.15NA optical fiber using polarization and optical fiber coupling technology. More than 75W output power is obtained, coupling efficiency exceeds 88%. Optical fiber end face spot with uniformity of more than 90% can be achieved by coupling the square optical fiber, which provides an ideal light source for medium power applications with high beam quality requirements such as gold foil welding and cutting, wire stripping, medical, etc.
