APPLICATION DESIGNER v4.0

LIEKKI
TM application designer (LAD) is a versatile design tool for fiber applications providing a strong platform for simulating and optimizing fiber amplifiers, amplify spontaneous emission (ASE) sources, and fiber laser systems. The software is based on precise algorithms that account for all the reflections in the system – especially crucial for accurate laser and ASE light source simulations. The simulation engine also accurately accounts for large mode area and highly doped fibers. LAD v4.0 includes a full bending effects model for step index fibers (both mode field deformation and bending loss in multimode regime) and variable time steps for transient analysis that allows easier simulation of pulsed systems. In addition, LAD v4.0 comes with several add-ons: Design wizard, optimization tools, mode field calculator, active ions concentration conversion tools, LIEKKI
TM EasySplice integration. The software has a new calculation engine optimized for better convergence of high-reflectivity cavities. This allows faster and more accurate simulation of fiber lasers. Also, LAD v4.0 has an improved mesh algorithm that yields smoother 3D graphs. These come in addition to the existing features that make the LIEKKI
TM Application Designer a very powerful tool for simulating high-power continuous-wave (CW) and pulsed lasers: Transient analysis, SBS and SRS threshold estimations, inversion level calculation, Monte Carlo simulation etc. LAD supports the full application design and analysis process from early research, prototype and pilot stage to full volume production. The LAD user could be product designer, optical engineer, research scientist or student.
