第一个在室温和大气压下工作的固态脉泽最近被证明使用光泵自旋三重态作为增益介质。本文首先简要回顾了低温固体脉泽的研究现状，然后讨论了室温固体脉泽的发展：从有机并五苯脉泽到金刚石氮空位连续脉泽。我们的特点，这些微波激射器作为相干微波源和超低噪声放大器的操作之前，概述它们如何可以适应作为模型系统，探索室温腔量子电动力学。在讨论了室温固态微波激射器当前实施例所面临的挑战后，我们将探讨如何通过开发替代材料和微波激射机制来解决或绕过这些挑战。最后，我们推测如何脉泽的出现，可以在环境条件下工作可能会导致新的应用计量学和量子技术。
The first solid-state masers to operate at room-temperature and ambient air-pressure were recently demonstrated using optically pumped spin-triplet states as the gain medium. In this Perspective, we briefly review the previous state-of-the-art in cryogenic solid-state masers and then discuss the development of the room-temperature solid-state maser: from the organic pentacene pulsed maser to the diamond nitrogen-vacancy continuous-wave maser. We characterize the operation of these masers as coherent microwave sources and ultra-low noise amplifiers before outlining how they can be adapted to act as model systems in which to explore room-temperature cavity quantum electrodynamics. After discussing challenges facing current embodiments of the room-temperature solid-state maser, we explore how they might be addressed or by-passed altogether through the development of alternative materials and masing mechanisms. Finally, we speculate on how the advent of masers that can operate in ambient conditions might lead to novel applications in metrology and quantum technologies.
