Next Generation Epitaxy

epiray introduces Thermal Laser Epitaxy (TLE) – a novel technology for the deposition of high-purity thin films. Epiray is a spin-off of the Max Planck Society pioneering a new era of epitaxy research.

A new deposition technology that will significantly impact thin film research and production.


TLE adds significant flexibility and speed to thin-film research. Targets can be changed on a daily basis, and almost any material can be used. Layers of ultra-high purity can be deposited. Multiple cheap chambers can be used in parallel with one set of lasers, thus widely different materials can be used in parallel. Operating cost are low.

It allows to conduct many more experiments in a given timeframe, with more diverse elements, than any other epitaxy method on the market. Boost your research with TLE!

Learn more about our technology or check out our TLE system or laser substrate heater for thin film deposition system upgrades.


Our current product range consists of a complete TLE system (laser system with specialized vacuum chamber) and a laser heater for upgrading deposition systems to take advantage of our substrate heating technology. The laser heater can be used later as basic component to build up our TLE system.
