Organic microlasers have attracted much attention due to their unique features such as high mechanical flexibility, facile doping of gain materials, high optical quality, simplicity and low‐cost fabrication. However, organic gain materials usually suffer from aggregation‐caused quenching (ACQ), preventing further advances of organic microlasers. Here, a new type of microlaser from aggregation‐induced emission (AIE) material is successfully demonstrated. By introducing a typical noncrystalline AIE material, a high quality microlaser is obtained via a surface tension‐induced self‐assembly approach. Distinct from conventional organic microlasers, the organic luminescent material used here is initially nonluminescent but can shine after aggregation under optical pumping. Further investigations demonstrate that AIE‐based microlasers exhibit advantages to enable much higher doping concentrations, which provides an alternative way to improved lasing performance including dramatically reduced threshold and favorable lasing stability. It is believed that these results could provide a promising way to extend the content of microlasers and open a new avenue to enable applications ranging from chemical sensing to biology.

有机微激光器由于其独特的功能（例如高机械柔韧性，易掺杂的增益材料，高光学质量，简单性和低成本制造）而备受关注。但是，有机增益材料通常会遭受聚集引起的淬灭（ACQ），从而阻止了有机微激光器的进一步发展。在这里，成功地展示了一种由聚集诱导发射（AIE）材料制成的新型微激光器。通过引入典型的非晶AIE材料，可以通过表面张力诱导的自组装方法获得高质量的微激光。与传统的有机微激光器不同，此处使用的有机发光材料最初是不发光的，但在光泵浦下聚集后可以发光。进一步的研究表明，基于AIE的微激光器显示出能够实现更高掺杂浓度的优势，这为提高激光性能提供了另一种方法，包括大大降低了阈值和良好的激光稳定性。相信这些结果可以为扩展微激光器的含量和开辟新途径提供广阔的前景，从而使从化学传感到生物学的应用成为可能。
