nLIGHT Extends Performance of Long Wavelength Laser Diodes

Vancouver, WA  May 02, 2008 

Industry leading performance from 1.4 to 2.1 microns

nLIGHT has extended the performance of its high-power long wavelength semiconductor laser diodes ranging from 1.4 to 2.1 microns. Industry-leading power and efficiency over this wavelength range enables medical, defense, and material processing applications.

At 1.9 microns, the Pearl™ fiber-coupled module provides up to 20 watts output power from a single 400 micron 0.22 NA fiber with >10% wall-plug efficiency. Single emitter chips produce up to 1.5 watts rated power on expansion matched substrates.

At 1.4 and 1.5 microns, the Pearl™ module produces up to 40 watts from a single 400 micron 0.22 NA fiber and >30% wall-plug efficiency. Single emitter chips produce up to 3 watts rated power on expansion matched substrates.
