AI Technical Summary
Technical Problem
Existing methods for evaluating and monitoring the coupling quality of laser light into optical fiber units are inadequate, leading to difficulties in achieving optimal beam quality and power efficiency due to power plateaus and inefficiencies in detecting cladding light.
Method used
Incorporating a reflective element at the fiber end to deflect a portion of useful light away from the propagation direction, allowing for stable and reproducible assessment of coupling quality by measuring the back-reflected light, thereby avoiding power plateaus and improving beam quality detection.
Benefits of technology
Enables precise and reproducible assessment of coupling quality, ensuring consistent power and beam quality, and allows for automatic adjustment of the coupling process.
