摘要：
本文综述了有机固体激光器的研究进展，并着重介绍了近十年来发表的一些研究成果。有机激光器最初指的是固态聚合物基质中的染料，但随着有机发光二极管的快速发展，有机激光器还包括丰富的有机半导体家族。有机激光器是广泛可调谐的相干光源，具有潜在的紧凑、方便和低成本制造的优点。在这篇综述中，我们描述了用于有机激光器中的增益介质的材料的基本物理特性，特别是在染料和半导体的独特性。我们还概述了在国家的最先进的有机激光器和这些设备的性能方面的输出功率，寿命和光束质量的激光器架构。给出了该领域的最新趋势的调查，突出了在波长覆盖，波长灵活性，效率和紧凑性方面的最新发展，或向集成低成本源，特别关注实现直接电泵浦仍然存在的巨大挑战。最后，我们讨论了最近演示的新型有机激光器的基础上极化激元或表面等离子体激元，这在有机纳米光子学领域开辟了新的和非常有前途的路线。
英文摘要：
Organic solid-state lasers are reviewed, with a special emphasis on works published during the last decade. Referring originally to dyes in solid-state polymeric matrices, organic lasers also include the rich family of organic semiconductors, paced by the rapid development of organic light emitting diodes. Organic lasers are broadly tunable coherent sources are potentially compact, convenient and manufactured at low-costs. In this review, we describe the basic photophysics of the materials used as gain media in organic lasers with a specific look at the distinctive feature of dyes and semiconductors. We also outline the laser architectures used in state-of-the-art organic lasers and the performances of these devices with regard to output power, lifetime, and beam quality. A survey of the recent trends in the field is given, highlighting the latest developments in terms of wavelength coverage, wavelength agility, efficiency and compactness, or towards integrated low-cost sources, with a special focus on the great challenges remaining for achieving direct electrical pumping. Finally, we discuss the very recent demonstration of new kinds of organic lasers based on polaritons or surface plasmons, which open new and very promising routes in the field of organic nanophotonics.
