In this article we will explore in depth the topic of Laser dye, a topic of great relevance today that affects different sectors of society. We will investigate its origin, history and evolution over time, as well as its impact on people's daily lives. In addition, we will analyze different perspectives and opinions on Laser dye, with the aim of providing a broad and complete overview of this topic. Through this research, we aim to offer our readers a deeper understanding of Laser dye, so that they can form an informed opinion and contribute to the debate around this matter.
A Laser dye is a dye used as laser medium in a dye laser.[1][2]
Laser dyes include the coumarins and the rhodamines. Coumarin dyes emit in the green region of the spectrum, whereas rhodamine dyes are used for emission in the yellow-red. The color emitted by the laser dyes depend upon the surrounding medium i.e.the medium in which they are dissolved. However, there are dozens of laser dyes that can be used to span continuously the emission spectrum from the near ultraviolet to the near infrared.[3][4]
Laser dyes are also used to dope solid-state matrices, such as poly(methyl methacrylate) (PMMA), and ORMOSILs, to provide gain media for solid state dye lasers.[3]
Prior to 1988, only one laser dye, polyphenyl 1, had been shown to operate CW at wavelengths less than 400 nm.
