Leveraging nLIGHT’s proprietary nXLT™ technology, nLIGHT is pleased to announce the release of its 0.75 W 635 nm high-brightness single emitter diode laser. Available in either c-mount or HHL packages, this new product features 0.75 W of optical power from a 150 µm wide emitter at 635 nm. Primary applications include laser-based displays, machine vision, photodynamic therapy, and DNA sequencing.

“We are pleased to report an increase in rated power by 50% while maintaining the extended lifetime and high reliability that is a hallmark of our nXLT™ (eXtended Life Technology) process,” said Mark DeVito, VP of Device Engineering at nLIGHT.

Typical operating currents are around 1.5 A with a compliance voltage of 2.2 V and a wall-plug efficiency of over 20%. Spectral width is less than 3 nm, and typical beam divergence is less than 42 degrees full-width at half maximum (FWHM) in the fast-axis direction, and less than 10 degrees FWHM in the slow-axis direction. As an added feature, nLIGHT can include an antireflective-coated cylinder lens to collimate the fast-axis to less than 2 degrees, FWHM, with greater than 95% power transmission.

This product at 0.75 W and 635 nm complements nLIGHT’s 1 W and 1.5 W devices in the 660 to 690 nm region, allowing for several possible combinations via wavelength multiplexing. It is featured in our newly released 3 W 635 nm Pearl™ platform. For applications that need more than 1 W of power, or need a fiber-coupled output, Pearl™ provides the perfect solution of high-brightness, long lifetime, and ease of integration due to its compact size and plug-and-play electrical connections.
