LIEKKI Unveils 100W CW Optical Engine Modules

(Nanowerk News) LIEKKI Corporation, a leading supplier of highly doped fibers and optical engine modules for fiber laser and amplifier applications, recently announced the general availability of its 100W CW optical engine modules.
LIEKKI has moved forward from the prototype stage to general availability of its 100W CW optical engine modules. LIEKKI optical engines integrate the entire fiber amplifier or laser glass elements like active fibers, passive fibers, pump combiners, fiber Bragg gratings (FBGs), pump dumps and filters into a thermally engineered package. This enables fiber laser manufacturer or system integrator to dramatically reduce the product development time and to concentrate on the full system development and integration.
Today, LIEKKI OE-Yb-L-100 modules have completed final design and qualification, and we have started to accumulate many hours of these devices under test.
The current line of LIEKKI optical engine modules consists of ytterbium fiber based CW laser and amplifier modules emitting at the 1030-1090nm wavelength range, with output powers up to and exceeding 100W.
About LIEKKI Corporation
LIEKKI Corporation designs, manufactures and markets specialty optical fibers and fiber subassemblies (optical engine modules) for fiber amplifiers and lasers using its unique and proprietary Direct Nanoparticle Deposition (DND) technology. LIEKKI also provides design software for fiber lasers and amplifiers, LIEKKI Application Designer. The DND technology enables LIEKKI to produce state-of-the-art, highly doped fibers that minimize required fiber length, have large core-to-clad ratios, and exhibit low photodarkening, flat refractive index profile, high efficiency and reduced nonlinear effects. LIEKKI products are used in applications such as high power fiber lasers for industrial manufacturing, military and aerospace, medical applications, telecom amplifiers and ASE light sources.
Direct Nanoparticle Deposition (DND) is a new, innovative nanoparticle process invented, developed and commercialized by LIEKKI Corporation, for a wide range of industrial applications. LIEKKI has licensed DND to industrial customers for non-optical applications and will continue to do so.
LIEKKI Corporation is headquartered in Lohja, Finland. LIEKKI products are available globally through Thorlabs and the LIEKKI direct sales team serves Americas, Europe and Asia. LIEKKI products are also distributed and supported by the sales representatives FT Okura (Japan), IKG Corporation (Japan), OptoCom Equitech (M) Sdn Bhd (Southeast Asia), Apollo Electronics Co. Ltd. (China) and Connet Fiber Optics Company Ltd. (China).
