Key Points

To develop and evaluate a low-threshold, highly stable vertical cavity surface emitting laser utilizing all-inorganic CsPbBr3 perovskite quantum dots.
Fabricated a hybrid vertical cavity surface emitting laser (VCSEL) by sandwiching a CsPbBr3 perovskite quantum dot thin film between two highly reflective distributed Bragg reflectors.
Characterized the device's lasing threshold, temperature dependence, and operational stability under ambient conditions in short-pulse and quasi-continuous-wave regimes.
Achieved an ultralow lasing threshold of 0.39 μJ/cm² from the hybrid perovskite quantum dot vertical cavity structure.
Demonstrated continuous operational stability under ambient conditions for over 5 hours across 1.8 × 10⁷ optical pulse excitations without device degradation.
