An ultralow‐threshold microfluidic single‐mode laser is demonstrated by Emine Yegan Erdem, Hilmi Volkan Demir, and co‐workers in article number 2007131, who use an on‐chip cavity that has a colloidal quantum well solution as a microfluidic gain medium, which shows a record‐low threshold among all solution‐based lasers of 68 μJ cm −2 . This work presents a significant step toward the realization of practical solution‐based lasers from colloidal nanocrystals integrated into microfluidic devices designed for sensing and imaging applications.
