nLIGHT | Pearl™ Display & Entertainment Series

High-Power Semiconductor Lasers

PEARL™ DISPLAY & ENTERTAINMENT SERIES

The Pearl™ Display and Entertainment Series is optimized to meet the demanding requirements of consistent unit-to-unit performance with ease of integration. The red wavelength spectrum can be tailored to reduce speckle.

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

The Pearl™ uses a revolutionary fiber technology, PowerCore™, which eliminates mode sensitivity to fiber motion and optimizes consistency of 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.
5 Spectral width can be altered to reduce speckle
