If you’re designing a DPSS laser system or building a custom Nd:YVO₄ laser head, the V2-50-888-200 is a purpose-built 888nm diode laser module delivering high stability, narrow linewidth, and strong coupling efficiency through a 20 µm core fiber.
With 50W output power, 0.5 nm FWHM, and SMA905 connector, this fiber-coupled 888nm laser diode is ideal for solid-state laser pumping and precision optical setups.
This module combines advanced thermal design, wavelength accuracy, and a compact housing — making it perfect for integration into industrial, medical, or research DPSS systems.
Designed for 888nm DPSS Pumping and Scientific Integration
The 888nm wavelength is optimized for Nd:YVO₄ and Nd:YAG gain media, offering lower quantum defect than traditional 808 nm diodes. This enables:
- Lower heat load
- Better beam quality
- Higher optical conversion in gain media
The V2-50-888-200 offers:
- Peak output power of 50W CW
- Center wavelength at 888 nm ±0.5 nm
- Ultra-narrow 0.5 nm spectral width
- High slope efficiency (6 W/A) and PCE (45%)

Perfect for OEM DPSS Laser System Designers
This fiber-coupled 888 nm laser module with 20µm core is engineered for:
- Nd:YVO₄ / Nd:YAG laser pumping
- Compact or multi-module DPSS assemblies
- Scientific setups requiring stable and narrow-line 888 nm input
- OEM medical, industrial, or spectroscopic system builders
The small core diameter improves coupling precision into crystal rods or nonlinear optics, making it ideal for high-performance systems.
Why Choose 888 nm Over 808 nm for Laser Pumping?
888 nm has a lower quantum defect than 808 nm, which translates to:
- Less heat in laser crystals
- Reduced thermal lensing
- Better beam mode quality
- Longer system lifetime and higher efficiency
Many next-gen DPSS system designers are switching from 808 nm to 888 nm — and this 50W module is ready to power that transition.
