Single Emitter Diode Laser Devices

(Non Visible)

Leveraging nXLT™ technology, nLIGHT’s non visible single emitter diode laser devices span the wavelength region from 808 to 2000 nm. With emitting apertures from 100 to 200 µm, and power levels up to 5 W, these devices offer a rare combination of high brightness and high reliability, enabling new applications.

Our non visible single emitter diode laser devices are available in c-mount and high-heat load (HHL) packages, and we offer a variety of lensing options to meet the specific needs of your application.
