PEARL™ HIGH-BRIGHTNESS MODULES
nLIGHT’s Pearl™ high-brightness modules are available at 91x or 97x nm for pumping either erbium-based or ytterbium-based fiber lasers. They have desirable low numerical aperture (NA) optical outputs ideal for low loss in use with taper fiber combiners or increased working distances in direct materials processing applications.
The Pearl™ series offers unparalleled reliability and efficiency by coupling nLIGHT’s high-brightness nXLT™ single emitters with a proprietary optical design for efficient fiber coupling.

- >50% wall-plug efficiency
- Plug and play electrical connectors
- Superior efficiency
- High reliability
- Low current operation
- Compact
