Abstract
A simplified three‐rate‐equation model is proposed to study the dynamic behavior of a two‐section high‐power tapered laser. The model includes a traveling intensity approach to calculate the photon ratios in both sections. The simulations align with the experimental data of a 1060 nm distributed Bragg reflector two‐section tapered laser. The effect of driving conditions is analyzed on the peak power and pulse duration. The pulses it obtain experimentally are ≈100 ps with 4.2 W peak power at a 900 MHz repetition rate.
期刊介绍：
Annalen der Physik (AdP) is one of the world''s most renowned physics journals with an over 225 years'' tradition of excellence. Based on the fame of seminal papers by Einstein, Planck and many others, the journal is now tuned towards today''s most exciting findings including the annual Nobel Lectures. AdP comprises all areas of physics, with particular emphasis on important, significant and highly relevant results. Topics range from fundamental research to forefront applications including dynamic and interdisciplinary fields. The journal covers theory, simulation and experiment, e.g., but not exclusively, in condensed matter, quantum physics, photonics, materials physics, high energy, gravitation and astrophysics. It welcomes Rapid Research Letters, Original Papers, Review and Feature Articles.
