nLIGHT fibre coupled laser diodes are available on two platforms, the element and pearl.

nLIGHT element® is the industry’s leading semiconductor laser platform, providing exceptional brightness and performance in fibre core sizes down to 105 µm. These are the pump diodes of choice for high volume fibre laser and solid-state laser pumping.

The element builds upon nLIGHT’s foundation of single-emitter diodes, by incorporating them in a proprietary optical design for the most efficient fibre coupling. Cost and performance are optimised across the range of wavelengths from 793 up to 976 nm, and powers from 15 to 425 W. The modular platform consists of five packages, the e03, e06, e12, e18 & e24i, which feature an increasing number of emitters and power capability.

Many element wavelengths can be offered with VBG stabilisation for consistent performance across a range of operating conditions, and all feature wavelength appropriate feedback protection.

nLIGHT pearl™ semiconductor lasers provide diverse outputs to complement the element range. The range of wavelengths stretches from 793 up to 1550 nm, and power from 30 to 110 W with a variety of fibre combinations available to suit specific requirements.

The nLIGHT pearl platform is designed and manufactured to achieve the most efficient and reliable performance in solid state laser pumping, direct diode material processing and in surgical and medical therapeutics.

All nLIGHT laser diodes are supplied with eGraf thermal interface material but without heatsinking or control electronics. Should you require a controller please contact us for a recommendation.
