摘要：

Small size, high-brightness fiber-coupled laser modules have always been the ultimate goal that all researchers are pursuing. A high-brightness 525 nm wavelength fiber-coupled system is designed and evaluated. Based on a multichip 2D green laser diode array, fast-axis collimators are set inside the light source, and a beam shaping system that can rearrange the beam and improve the beam quality in both axes is designed. The simulation results indicate that 24 single emitters are coupled into a 50 mu m / 0.15 NA optical fiber successfully and the output power is 22.55 W. The brightness of 16.25 MW / ( cm(2) center dot sr ) is calculated with fiber coupling efficiency is 97%.
