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 …

Laserlike emission in powders of praseodymium-doped oxisulfides of yttrium, lanthanum,
and gadolinium has been reported in References [1, 2] under laser pumping (at different …

In this volume, six review articles which cover a broad range of topics of current interest in
modern optics are included. The first article by S. Saltiel, AA Sukhorukov and YS Kivshar …

Over the last decade, significant advances have been made toward the development of
practical, tunable solid state dye lasers, which resulted in improved lasing efficiency with …

Both localization and laser theory were developed in the 1960s. Light scattering was
traditionally considered detrimental to laser action because such scattering removes …

When films of π-conjugated polymers are optically excited above a certain threshold
intensity, then the emission spectrum acquires a multimode finely structured shape, which …

A new method, to our knowledge, is proposed that enables single-shot measurements of the
temporal coherence properties of pulsed laser sources. By modification of a Michelson …

A novel scheme for generation of laserlike emission from highly scattering media is
presented. A high degree of directionality is obtained owing to the excitation of surface …

The photon statistics of the random laser emission of a Rhodamine B doped di-ureasil
hybrid powder is investigated to evaluate its degree of coherence above threshold. Although …

There exists a formal analogy between the Schrödinger equation describing electron motion
in a random potential, and the scalar wave equation for light propagation in a medium with …
