摘要： Surface-emitting distributed feedback (SEDFB) lasers (10) having a curved grating (30) with a shape that produces good beam quality. A preferred shape is one for which the grating curves away from the center of the gain region (31) of the laser (10). The use of the curved grating (30) of the present invention produces good beam quality from broad area SEDFB lasers with high power and high efficiency. The present invention overcomes self-induced filament formation and dynamic instabilities that limit achievable beam quality. The present invention provides for a holographic method for fabricating curved gratings (31) for the SEDFB lasers (10) that is consistent with laser batch processing.
摘要翻译：表面发射分布反馈（SEDFB）激光器（10）具有弯曲光栅（30），其具有产生良好光束质量的形状。优选的形状是光栅远离激光器（10）的增益区域（31）的中心的形状。本发明的弯曲光栅（30）的使用由具有高功率和高效率的广域SEDFB激光器产生良好的光束质量。本发明克服了自我诱导的细丝形成和限制可实现的光束质量的动态不稳定性。本发明提供一种用于制造与激光批处理一致的SEDFB激光器（10）的弯曲光栅（31）的全息方法。
