nLIGHT | Pearl™ Material Processing Series

High-Power Semiconductor Lasers

PEARL™ MATERIAL PROCESSING SERIES

The Pearl Materials Processing Series is optimized to meet the demanding industrial requirements of continuous performance with ease of integration.

nLIGHT’s proprietary single-emitter integration technology enables industry-leading efficiency and reliability, thus minimizing system footprint and maximizing reliability.

These pump lasers use a revolutionary fiber technology, PowerCore™, which eliminates mode sensitive to fiber motion, which maximizes consistency of light on part performance.

1 Numerical aperture (NA) is the sine of the half-angle encircling 90% of the optical energy from the fiber.
2 A non-condensing environment is required for storage and operation.
3 Thermal resistance is the diode junction temperature shift per incremental Watt of heat load.
4 The wavelength temperature coefficient is the wavelength shift per °C change at the diode junction.
