Femtosecond pulses are drawing more and more attentions in modern optical applications, because of their ultrashort temporal duration and the corresponding ultrahigh power. The ultrashort temporal duration also leads to broad spectrums. Such spectral or temporal properties of femtosecond pulses must be properly handled together with their spatial behaviors for the modeling.
VirtualLab Fusion provides such a physical-optics simulation platform capable of femtosecond pulse modeling.
Refractive beam shapers are of great help in several laser-related applications. For example, in material processing, laser beams are often required to have uniform distributions (like top-hat) on the target plane.
In VirtualLab, refractive beam shapers can be designed with a user-friendly workflow, and the design results can be exported directly in those formats most commonly used for fabrication.
Microlens arrays can be found in different applications, such as imaging, wavefront sensing, and so on.
With the physical-optics simulation technique in VirtualLab, the working principle of the microlens array, e.g. in the case of wavefront sensing, can be clearly demonstrated, and the performance of such systems can be evaluated efficiently. It is also worth mentioning that the diffraction effect from the edge of the individual microlenses can be taken into consideration in the simulation.
How to ensure a high-efficient coupling of light into optical fibers is an important question in all fiber-related applications.
In VirtualLab, the focal field behind the coupling lens can be easily calculated with the fast physical optics simulation engine, and by calculating the overlap integral, the fiber coupling efficiency can be evaluated. Additionally, with the parametric optimization, the lens parameter can be optimized for customized situations.
