報告分享 | 半導體激光光源和光學整形的協同發展

Time：2020-06-29

2020年6月24日，炬光科技董事長兼CEO劉興勝博士受邀在EPIC（歐洲光電產業協會）舉辦的24小時環球直播中發表題為《推動高功率半導體激光器的應用和增長：半導體激光光源和光學整形的協同發展》的演講。

與固體激光器、光纖激光器和氣體激光器等其他類型的激光器相比，高功率半導體激光器在效率、可靠性、成本、尺寸等各方面都具有優勢。所有可以應用半導體激光器的場景，一定會使用半導體激光器。然而，無論EEL（邊發射激光器），還是VCSEL（垂直腔面發射激光器），激光光束質量都較差。尤其是EEL的光束質量在快慢軸極端不對稱：快軸方向BPP（Beam Parameter Product）良好，慢軸方向BPP很大。因此，半導體激光器光束質量差的特性決定了它目前不是主流應用的選擇。但劉興勝博士認為，并非所有實際應用都需要高光束質量的激光，只要滿足應用對能量密度、光束形狀和能量分布的要求即可。高光束質量的激光當然比較容易滿足以上三個要素，但通過微光學透鏡對激光進行整形，使光子在合適的時間出現在合適的位置，低光束質量的激光便可以為我們所用。同時，整形后的光斑在眾多應用中表現出獨特的優勢，如線光斑、面光斑在應用于焊接、激光剝離和退火等領域時可大大提升加工效率；應用于Flash LiDAR時可以減少運動部件的使用（如機械部件或MEMS），從而大幅提高系統可靠性。

炬光科技微光學透鏡能夠在零維（點）、一維（線）、二維（面）三個維度對各類型激光器進行光束整形。無論何種入射光源類型（VCSEL芯片、VCSEL陣列、EEL/Nanostack、DPSSL/光纖激光器），其光束形狀如何，光束質量如何（發散角大小、是否對稱），整形后均可形成圓形、矩形、線形等各種光斑形狀，滿足激光加工需求；也可形成較大的發散角，滿足照明、3D感知等應用需求。

雖然光學整形不能提升激光器的整體光束質量，但可以通過調節不同方向（快軸、慢軸）的光束質量，滿足特定應用對激光能量密度、光束形狀和能量分布三要素的要求，應用于OLED柔性顯示生產中的激光剝離、玻璃退火、塑料焊接、半導體退火、金屬表面處理、鐵路軌道檢測、自動駕駛激光雷達等領域。

高功率半導體激光器與微光學光束整形技術的協同發展，拓寬了半導體激光器的應用邊界，從而達到1+1>2的效果。
