摘要
Blue High-Power/High-Brightness Direct Diode Lasers are rapidly evolving as one of the preferred laser technologies for processing highly reflective materials. This paper focuses on the recent advances applying Wavelength Beam Combining (WBC) technology to diode bars emitting in the 445nm region to demonstrate the power scalability with high beam qualities only achievable using WBC technology. We’ll present our latest developments including 400W Blue lasers coupled with fiber diameters ≤50um. We will also show results of combining multiple laser modules to scale powers to multi-KW levels with fiber diameters ≤ 100um. Finally, we will discuss the future of this technology.
