When your application demands extreme output power, narrow linewidth, and long-term spectral stability, the V2-120-880-200 delivers. This fiber-coupled 120W 878.6nm diode laser module combines a compact footprint with exceptional electro-optical efficiency, making it a top choice for solid-state laser pumping, scientific R&D, and high-reliability OEM integration.
With 14 W/A slope efficiency and a 0.5 nm FWHM spectrum, this high-power diode offers outstanding beam control, thermal performance, and wavelength lock compatibility for precision optical systems.
Why 878.6nm is the Smart Choice for DPSS Pumping?
The 878.6nm center wavelength closely matches absorption bands of Nd:YAG and Nd:YVO₄ crystals, providing:
- Lower quantum defect and reduced thermal lensing
- Higher optical-to-optical conversion rates
- Improved beam quality and system efficiency
- Compatibility with volume Bragg grating (VBG) stabilization
Compared to conventional 808nm sources, the 878.6nm spectrum ensures long-term performance and higher energy output in demanding pump applications.
