X-ray lasers: Why does brighter mean darker?
When we illuminate something, we usually expect that the brighter the source we use, the brighter the resulting image will be. This rule also works for ultra-short pulses of laser light—but only up to a certain intensity. The answer to the question.....»»
Radiation build-up and dissipation in Raman random fiber laser
Raman random fiber lasers (RRFL) have attractive features, such as their simple structure, excellent wavelength-tunability and high optical-optical conversion efficiency. They show great potential for long-distance fiber sensing, speckle-free imaging.....»»
