Abstract
A practical and simple approach of achieving a high pulse repetition frequency fiber-coupled laser-diode device is demonstrated both by experiment and TRACEPRO software simulation, which is obtained by beam collimating, spatial beam combining, and polarization beam combining based on multiple cycle-emitting pulsed laser-diode emitters. Using this method, fiber-coupled laser-diode module output pulse repetition frequency from the multimode fiber with 200 - μ m core diameter and 0.22 numerical aperture can reach 300 kHz, and the coupling efficiency is beyond 72%. This technique has superiors of great flexibility, low cost, and high reliability for wide applications.
