nLIGHT | Pearl™ Fiber Laser Pump Series

High-Power Semiconductor Lasers

PEARL™ FIBER LASER PUMP SERIES

The Pearl™ fiber laser pump series is optimized to meet the demanding requirements of high brightness pumping with minimal cladding light and imbedded feedback protection.

Pearl™ pump lasers use a proprietary fiber coupling technology to eliminate light in the cladding. nLIGHT’s proprietary single-emitter integration technology enables high power pumping without the need for fiber combiners, thus maximizing efficiency, cost-effectiveness and useful life.

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.
