In a recent Nature study, scientists have demonstrated an electrically driven perovskite laser using a dual-cavity design, addressing a challenge that has persisted in the field for over a decade.

The dual-cavity laser device developed by a team from Zhejiang University shows a lasing threshold an order of magnitude lower than state-of-the-art electrically driven organic lasers and offers superior operational stability with rapid modulation capabilities.
