Fundamentals of Organic Lasers,are important for organic lasers and specific to them, and which are therefore not usually treated in classical textbooks on lasers. The objective of this chapter is to present a quite general, while not exhaustive, overview of the photophysics of organic compounds that are directly useful to unders作者: 合并 時(shí)間: 2025-3-22 00:55 作者: affluent 時(shí)間: 2025-3-22 08:21 作者: 火車(chē)車(chē)輪 時(shí)間: 2025-3-22 10:25 作者: doxazosin 時(shí)間: 2025-3-22 14:39 作者: 子女 時(shí)間: 2025-3-22 18:29

Organic Materials for Solid-State Lasers, chemical structure and the optical properties of some of the main families widely used as gain materials or host matrices in organic lasers. The technological processes allowing organic molecule deposition in various forms are then reviewed, as well as the main experimental techniques used to measure crucial parameters such as optical gain.作者: 遺傳學(xué) 時(shí)間: 2025-3-24 17:40

Novel Concepts for Organic Lasers,h as laser diodes or even light-emitting diodes, could be used. A fundamental challenge which remains to be solved is the realization of a true CW laser with an organic solid-state medium.
