Книга: Mohammed Hameed «Amplified Spontaneous Emission of Random Gain Laser Media»

Производитель: "LAP Lambert Academic Publishing"

The random laser is a non-conventional laser whose feedback mechanism is based on random scattering, as opposed to the reflective feedback by the mirrors of a conventional laser. This alternative feedback mechanism has important application to lasers in the spectral regime where an efficient reflective element is not available, e. g., UV laser, x-ray laser. Materials or `gain media` that generate conventional lasers are put in an ordered structure known as `lossless resonators` - often mirrors - that generate light without losing much of it. Random laser materials, in contrast, are disordered and lose some light. Or as Vardeny puts it: `You can get lasing out of junky materials if they contain molecules that glow. Out of disorder comes perfect order.` Random lasers using R6G dyes gain medium together with TiO2 nanoparticles has proven to be a reliable method in producing such optimum and exceptional lasing.
