Researchers at the University of Turku have demonstrated a solid-state organic laser microcavity fabricated entirely by solution processing.

The device operates in the strong light–matter coupling regime, where light and matter form hybrid states called polaritons.

This makes the platform not only a new type of solution-processed laser but also a powerful way to study nonlinear polariton interactions.

Solid-state lasers are used in many modern technologies, from telecommunications and sensing to medical diagnostics and data storage. However, their fabrication often requires complex and energy-intensive manufacturing methods.

This new work shows that organic laser devices can be made in a much simpler way, by coating each layer from a liquid solution rather than depositing it in vacuum.
