Seeing the light: high-power visible-light generation using silicate fibre

与近红外激光器不同，可见光发射激光器效率低且复杂，影响了它们在工业、医药和电信领域的更广泛部署。为了解决这个问题，我们将创造一种基于全新掺杂硅酸盐玻璃纤维的新型激光和放大器，这种光纤将显示出低背景损失和对高功率可见光的光降解的弹性。这将解决光纤激光器研究中最后的重要问题之一。主要成果将是一系列高功率连续波、超短脉冲、全光纤激光器，在黄色和红色波长发射，对太空、国防、制造和人类健康具有重大好处。

Unlike their near-infrared counterparts, visible-light-emitting lasers are inefficient and complicated, impacting their broader deployment in industry, medicine, and telecommunications. To address this, we will create a new class of laser and amplifier based on an entirely new doped silicate glass fibre that will display low background loss and resilience to photodegradation from high-power visible light. This will solve one of the last important problems in fibre laser research. The primary outcome will be a series of high-power continuous-wave, ultrashort-pulse, all-fibre lasers emitting at yellow and red wavelengths, with significant benefits for space, defence, manufacturing, and human health.
