It is perhaps surprising that something as fragile as a microscopic droplet could possibly form a laser. In this article we will review some of the underpinning physics as to how this might be possible, and then examine the state of the art in the field. The technology to create and manipulate droplets will be examined, as will the different classes of droplet lasers. We discuss the rapidly developing fields of droplet biolasers, liquid crystal laser droplets and explore how droplet lasers could give rise to new bio and chemical sensing and analysis. The challenges that droplet lasers face in becoming robust devices, either as sensors or as photonic components in the lab on chip devices, is assessed.
令人惊讶的是，像微观液滴这样脆弱的东西竟然有可能形成激光。在本文中，我们将回顾一些潜在的物理原理，探讨其实现的可能性，然后研究该领域的最新技术。我们将探讨创建和操控液滴的技术，以及不同类型的液滴激光器。我们讨论了液滴生物激光器、液晶激光液滴这两个快速发展的领域，并探索了液滴激光如何为新的生物和化学传感与分析带来可能。本文还评估了液滴激光器在成为可靠的设备（无论是作为传感器还是作为实验室芯片设备中的光子元件）方面所面临的挑战。
