高功率直驅式半導體雷射之發展

Developments of High Power Direct Diode Lasers

Abstracts


雷射製造已成為世界上不可抵擋之趨勢,其中金屬切割與銲接工程需求不斷地成長,雷射源技術都對應著不同加工應用來推陳出新,過去從二氧化碳雷射進展到光纖雷射後,研究方向開始探討更有效率的製造方式來因應加工需求。進步至今,直驅式半導體雷射的建構技術已開始逐步發展。時間快速推進,具有40%以上的電光效率和小於4 mm.mrad之光束特性的雷射系統設計中,具備無需復雜的光纖元件熔接與架構簡單之特徵。其證明高品質的直驅式半導體雷射可有效地加工材料,本文將針對過往的高功率雷射製造技術到目前新世代的直驅式半導體雷射進行介紹。

Laser processing has become irresistible trend in the world. The demand for metal cutting and welding continues to grow and the laser source technology is designed to cope with different processing applications. This technology has evolved from carbon dioxide laser to fiber laser in the past. Currently researches have focused on exploring more efficient manufacturing methods to meet different processing applications. The fundamental technology for direct diode lasers (DDL) starts to develop gradually and advances quickly with time. The DDL system is to be designed with more than 40% of electro-optic efficiency and less than 4 mm.mrad beam characteristics. With its simple structure there is no need to use complicated fiber optic component fusion. It has been proved that the high-quality DDL laser system can process materials effectively. This study will introduce high-power laser processing technology from the past to the current generation of DDL.
