Drawing:
We are excited to introduce our 15W F Mount Laser Diode featuring the precise 878.5nm wavelength - a unique window highly valued in advanced laser pumping, medical, and scientific research applications.
Why 878.5nm?
The 878.5nm center wavelength offers distinct advantages:
Optimized absorption for Nd:YVO4 and other crystal pumping systems
Reduced thermal load compared to conventional 808nm solutions, improving system stability
Excellent beam absorption efficiency in certain medical and scientific applications
Ideal for specialized materials processing where tight wavelength tolerance is critical
Unlike general-purpose wavelengths, 878.5nm allows you to achieve higher system efficiency, better thermal management, and longer device lifetime.
Customization Available:
We offer full customization to meet your system requirements, including wavelength-locked (stabilized) versions, FAC beam shaping, and fiber coupling solutions.
If you are seeking a reliable, efficient, and application-optimized solution, our 878.5nm 15W F-Mount Laser Diode may be your ideal choice.
