WORLDTECHVilnius team reports perovskite laser stable over 400 million pulses
Researchers at Vilnius University have demonstrated perovskite-based laser structures that kept performing steadily through more than 400 million pulses, according to a study published in Advanced Optical Materials and reported by Phys.org. The result targets instability, the problem that has most limited the practical use of these materials.
What the Vilnius study shows
The study, published in Advanced Optical Materials, comes from researchers at Vilnius University (VU). According to the report, the team built perovskite-based laser structures whose performance remained stable across more than 400 million pulses.
Why instability has held perovskites back
Perovskites are semiconductor materials that could play an important role in next-generation optical technologies. Their tendency to degrade, however, has long been a challenge for researchers around the world, and the Vilnius findings are aimed directly at that weakness.
Open questions
- Will the stability seen in these laser structures carry over to other device designs?
