nLight has released version 4.0 of the Liekki Application Designer (LAD). LAD is a design tool for high-power applications providing a platform for simulating and optimising fibre amplifiers and fiber laser systems.
The design software is based on precise algorithms that account for all the reflections in the system – especially crucial for accurate laser and amplified spontaneous emission (ASE) light source simulations. The software also accurately simulates large mode area and highly doped fibers.
New LAD v4.0 features include: multimode analysis of bent fibres; variable step size in transient analysis; optimisation tool; and LAD wizards.
Useful add-ons in LAD v4.0, include: a concentration conversion table; Liekki EasySplice integration, and mode field and cutoff calculation.
