中文摘要半导体列阵量子效率高,输出波长范围涵盖570~1600nm,工作寿命可达数百万小时,叠层列阵可提供超高功率激光输出,在工业、医学等很多领域具有非常广阔的应用前景。但列阵在自由运行时,各发光单元发出的光是不相干的,输出质量差,采用1/4Talbot外腔镜耦合技术,列阵实现了空间锁相最高阶超模,然而唯有基超模远场分布是中心单瓣结构,输出接近衍射极限。为得到最小谱宽、最小发散角、最大功率密度输出,必须将外腔镜倾斜β=λ/2d(λ为工作波长,d为列阵周期),这使得仅有基超模光能成像于发光单元内而被允许振荡。应用此; Laser diode array can operate with high quantum efficiency,output wavelength can range from 570 nm to 1 600 nm,and hours of work can be even longer than mega hours.Multi-array stack of Laser Diode Arrays(LDAs) can supply ultrahigh power laser beam and are becoming widespread sources for many kinds of applications involving regions of industries,medicine etc.However,a free-running LDAs always operate on a wide bandwidth with the poor coherence,the laser beam cannot be focused to a small spot with a well-defi...
