Simulation in Photonics

Realizing the Transparent Laser

When developing a fiber laser (or in fact any other kind of laser), one of the main challenges is that you cannot simply look into the device to see what exactly is going on inside. That makes it difficult, of course, to find out how exactly to fix certain problems and optimize the performance.

Wouldn't it be marvelous if you had a “transparent laser”, where you can easily see e.g. what are the optical intensities and excitation densities anywhere in the fiber, including their temporal evolution with arbitrary resolution? It turns out that this is possible — with computer simulation of lasers (or e.g. ultrafast amplifier systems), which can be done with our software. These are extremely helpful tools

for acquiring a detailed understanding of what goes on inside such devices,
and thus also for optimizing their designs.

Presentation on Efficient Laser Development With the Transparent Laser

In the following, we present a 25-minute video, where Dr. Paschotta explains

what special challenge you face in laser development,
how a computer model can be used to effectively obtain a transparent laser, and
how you can in practice work with a laser model, greatly reducing the cost and time required for the development.

Enjoy the video and take home important insights on how to make your laser development more efficient!

You can also download the presentation as a PDF document.
