Recent developments in the field of micro and nanophotonics have shown that it is possible
to make use of the intrinsic disorder in photonic materials to create useful optical structures …

A random laser is a non-conventional laser whose feedback mechanism is based on
disorder-induced light scattering. Depending on whether the feedback supplied by …

Discussing theory and transport, synthesis, processing, properties, and applications, this
second edition of a standard resource covers advances in the field of electrically conducting …

A random collection of scatterers in a gain medium can produce coherent laser emission
lines dubbed “random lasing.” We show that biological tissues, including human tissues, can …

Many significant fundamental concepts and practical applications have developed since the
publication of the best-selling second edition of the Handbook of Conducting Polymers. Now …

The random laser represents a non-conventional laser whose feedback is mediated by
random fluctuation of the dielectric constant in space. Depending on whether the feedback is …

We report on a new random laser phenomenon that gives rise to narrow emission modes
without requiring optical cavities. Sharp emission peaks are observed experimentally over a …

Recent theoretical work on random lasing predicts that the occurrence of narrow lasing
spikes can be caused by both localized and extended modes of light,,. Typical random …

In conventional lasers, the optical cavity that confines the photons also determines essential
characteristics of the lasing modes such as wavelength, emission pattern, directivity, and …

We demonstrate low-threshold lasing in random amplifying layered medium via photon
localization. Lasing is facilitated by resonant excitation of localized modes at the pump laser …
