PEARL™ HIGH-EFFICIENCY MODULES
nLIGHT’s Pearl™ high-efficiency modules are available at 80x or 88x nm for pumping neodymium-based materials, 78x to 79x nm for pumping thulium-based or holmium-based materials, 938 nm for disk laser pumping, and other custom wavelengths ranging from 639 to 2050 nm.
They also possess desirable low numerical aperture (NA) optical outputs ideal for end-pumping rods to achieve superior TEM00 performance. Optional 600 µm fiber assemblies or afocal configurations are available.
