LASCAD™ Provides Multiphysics Simulation to Optimize Laser Resonator Design
The 3-D nonlinear interaction of thermal and optical fields, commonly known as thermal lensing effect, is one of the key problems which need to be analyzed to optimize design of laser cavities for solid-state lasers (SSL, DPSSL etc.). Thermal lensing interferes with gain guiding and other effects that control beam quality and efficiency of a laser in a complicated manner.
Numerical analysis of these effects is of growing importance due to the tendency to miniaturize laser cavities and simultaneously to increase their output power, causing the interaction of strong fields in very small volumes.
The industry-leading software package LASCAD combines all simulation tools necessary to model these effects. Based on a quantitave understanding of the multiphysics effects in laser cavities, LASCAD allows the laser engineer to control and compensate individual features of a resonator design prior to committing hardware.
LASCAD offers:
- Thermal and Structural Finite Element Analysis (FEA) of thermal effects in laser crystals,
- ABCD Gaussian Beam Propagation taking into account thermal lensing effects, gain guiding etc.
- 3D Wave Optics Beam Propagation Code including diffraction, gain saturation etc.
- Numerical Eigenmode Analysis.
- Beam Propagation outside the laser cavity
