LOHJA, January 20, 2006 – Liekki, a leading supplier of highly doped optical fibers and modules, is releasing the latest version of its simulation software, Liekki Application Designer, with essential tools for low to high power fiber laser and amplifier simulation.
Liekki Application Designer (LAD) v3.1 includes tools for designing systems employing large mode area fibers for the first time in a commercially available fiber amplifier and laser simulator.
“Liekki Application Designer v3.1 builds on the popular v3.0 strengthened with new essential features such as multimode propagation, user defined refractive index profile and fiber bending effects,” explains Dr. Mircea Hotoleanu, Product Manager for Liekki design software. “The software can be used to simulate fiber amplifiers and lasers using conventional fibers, as well as the unique features of Liekki Direct Nanoparticle Deposition (DND) fibers – such as radial doping profiles and unique refractive index profiles,” he continues.
With the multimode propagation LAD can now calculate the optical power propagation along the doped fiber for each mode in multimode fibers. Thus, the user can evaluate the quality of the output optical beam. In addition, LAD v3.1 calculates now the modes for any refractive index profile having radial symmetry. In virtually any application, the optical fiber is bent either for packaging purposes or to discriminate against higher order modes. LAD v3.1 includes now the bending effects in the calculations including mode field distortion and power loss. These new tools come in addition to many other existing features such as radial doping, transient calculations, Monte Carlo analysis and nonlinear effects threshold power.
According to Dr. Hanna J. Hoffman, Liekki’s CTO, “This latest version of LAD with its additional features responds to the needs of many of our customers. With its enhanced features it allows bridging the gap between the application designer and fiber manufacturers, a long awaited development for fiber laser systems. LAD v3.1 can, in particular, allow optimization of fiber parameters matched to application specifications as well as serve as a sanity check and comparison tool between different types of fibers and pump characteristics.”
Liekki Application Designer v3.1 will be launched at Photonics West ’06 where its capabilities will be demonstrated. The product will be available starting February 1st , 2006 through Liekki (one copy of the standard version is free of charge for Liekki’s customers) and also through Thorlabs. The software is compatible with most standard PCs running Microsoft Windows operating systems. For further information, please contact our sales staff, email liekkiliekki.com, or visit our website at www.liekki.com for a demonstration or a free 2 week trial download. Also multiple licenses of LAD are available through Liekki University Program.

About Liekki Corporation
Liekki designs, manufactures and markets specialty optical fibers and fiber subassemblies (optical engines) for fiber amplifiers and lasers using its unique and proprietary Direct Nanoparticle Deposition
(DND) technology. DND makes it possible 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 fibers also have very good usability in terms of splicing properties, temperature and bending characteristics. 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, 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 is headquartered in Lohja, Finland. Liekki products are available globally through Thorlabs (www.thorlabs.com). Liekki direct sales serves North America, Europe and Asia, supported by our representatives FT Okura (Japan), IKG Corporation (Japan), Apollo Electronics Co. Ltd. (China), and Connet Fiber Optics Company Ltd. (China). For further information, please visit our website at www.liekki.com.
