Pearl Long Wavelength Laser Diodes

nLight has extended the performance of its high-power long wavelength semiconductor laser diodes ranging from 1.4 to 2.1µm. 

At 1.9µm, the Pearl fibre-coupled module provides up to 20W output power from a single 400µm 0.22NA fibre with >10 per cent wall-plug efficiency. Single-emitter chips produce up to 1.5W rated power on expansion matched substrates.   

At 1.4 and 1.5µm, the Pearl module produces up to 40W from a single 400µm 0.22NA fibre and >30 per cent wall-plug efficiency. Single-emitter chips produce up to 3W rated power on expansion matched substrates.
