A brief review is given of the state of the art in the research on the photosensitivity of fibres
and photoinduced fibre gratings. The most important properties of fibre gratings are …

Optical fiber telecommunications depend upon light traveling great distances through optical
fibers. As light travels it tends to disperse and this results in some degree of signal loss …

Tunability has added an important dimension to a variety of laser devices and led to new
systems and applications. From laser spectroscopy to Bose-Einstein condensation, the one …

Deals with photonics in free space and special media such as anisotropic crystals.* Covers
all important topics from Fourier optics, such as the properties of lenses, optical image …

The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous
development in the past decade or so, transforming itself from a research curiosity to a major …

Coherent addition of fiber lasers coupled with an intracavity fiber coupler is reported. Almost
a single output is obtained from one of the fiber ports, which one can switch simply by …

Дан краткий обзор современного состояния исследований в области
фоточувствительности волоконных световодов и фотоиндуцированных волоконных …

A review of recent results on medium-power CW Raman fiber lasers pumped by laser
diodes is presented. Most attention is given to Raman lasers based on phosphosilicate …

We demonstrate a high-efficiency random lasing in a 850 m span of a phosphosilicate fiber.
Random distributed feedback owing to the Rayleigh backscattering in the fiber enables …

Vibrational spectra of phosphosilicate glasses with P2O5 concentrations up to 15 mol% are
investigated by the methods of Raman spectroscopy and quantum-chemical modeling. We …
