Phillip Rall: Improving High-Power Laser Optics

Symbolic picture for the article. The link opens the image in a large view.

Thermal lensing is an unwanted effect in optics used for high-power laser imaging. The high light intensity causes a heat up of the lenses which induces a focus shift. To tackle this issue, Phillip Rall recently presented a “Simulation and compensation of thermal lensing in high-power optical systems” using a combination of the finite element method and ray tracing. By this approach new methods for compensation of thermal lensing are enabled.

Phillip Rall works at the Chair for Computer Science 10 – System simulation, his supervisor is Christoph Pflaum. The original publication can be found here.
