Perovskite laser keeps working through 400 million pulses
In short
- Vilnius University researchers published the study in Advanced Optical Materials.
- The perovskite laser structures held stable performance over more than 400 million pulses.
- Instability has long limited the practical use of perovskite semiconductors.

Perovskites could matter for next-generation optical technologies, but they tend to degrade quickly. A laser that holds steady over 400 million pulses addresses that weakness directly. This is a laboratory result, so it shows a path rather than a finished product.

In a study published in Advanced Optical Materials, researchers at Vilnius University (VU) demonstrated perovskite-based laser structures that maintained stable performance over more than 400 million pulses. Their findings address one of the major challenges limiting the practical use of perovskites: their instability. These semiconductor materials could play an important role in next-generation optical technologies, but their tendency to degrade has long posed a challenge for researchers worldwide.
