摘要

只提供摘要形式。高功率半导体激光器在光谱学、电信、制造业和材料加工、医学、自由空间通信或能量传输等领域都有应用。/spl sim/1 W或更高的功率需要大孔径/spl sim/100 pm，这会导致高阶横向模式、灯丝和时空不稳定性，所有这些都会降低空间相干性，从而降低亮度。本文介绍了近年来在抑制丝化和高阶横模振荡的激光结构和谐振器开发方面的理论和实验研究。我们制造并分析了广域激光器、不稳定谐振器和喇叭激光器。

High brightness semiconductor lasers by inhomogeneous pumping

Summary form only given. High power semiconductor lasers have applications in spectroscopy, telecommunications, manufacturing and materials processing medicine, free space communication or energy transfer. Powers of /spl sim/1 W or more require large apertures /spl sim/100 pm which lead to high order transverse modes, filamentation and spatio-temporal instabilities, all of which degrade spatial coherence and therefore brightness. In this paper we describe recent theoretical and experimental research to develop laser structures and resonators to suppress filamentation and high order transverse mode oscillation. We have fabricated and analysed broad area lasers, unstable resonators, and flared lasers.
