Perovskite Laser Structure Remains Stable Beyond 400 Million Pulses
Start here
On October 22, 2026, Phys.org reported that a perovskite laser structure demonstrated by a Vilnius University research team retained stable performance after more than 400 million pulses. The team prepared a material in which part of the lead is replaced by zinc using spin coating in a nitrogen environment, analyzed its properties with confocal luminescence measurements, and then formed a DFB grating by interferometric laser ablation. The related study was published in Advanced Optical Materials, and the sample combines good stability with a narrow emission line.

A perovskite laser structure demonstrated by a Vilnius University research team maintained stable performance after more than 400 million pulses. The team prepared a material in which part of the lead is replaced by zinc using spin coating in a nitrogen atmosphere, analyzed its properties with confocal luminescence measurements, and then formed a DFB grating by interference laser ablation. The research was published in Advanced Optical Materials, and the samples combine good stability with narrow emission lines.
