摘要

The paper contains a review of a recent development in the random laser generation in spatially inhomogeneous systems. The focus is on random Raman lasers, second harmonic generation and multiphoton excited laser generation. In the paper, both the basic principles of random lasing and the most interesting practical applications are considered, especially those related to the use of random lasers as radiation sources for obtaining speckle-free high-quality images and to applications in medicine being used both in deceases diagnostics and therapy. Recent experimental results of the paper authors are also presented, in particular temporal characteristics of random Raman lasers radiation.
