The experimental realization of a laser which provides direct coupling of the inside cavity field with optical filter is discussed, and its general features are considered. A laser dye was used as an active medium. The authors call such laser a cavit

The first experimental realization of a laser cavity with direct optical fiber taper output is discussed. It provides active self-insertion of the powerful laser emission into the optical fiber. A high quality smooth field distribution is observed at

We have shown, for the first time to our knowledge, that the self-compression of high intensity femtosecond optical pulses, preceding by self-focussing, is a general phenomenon that can be observed in different optical media, providing proper control

The efficiency of the nonlinear processes in optical fibers (OFs) depends both on the specific material and waveguide parameters of the fibers and on the basic pump-laser parameters-intensity and spectral bandwidth. In the paper the authors report on

International audience; The nonlinear optical interactions represent a rich source of phenomena, that has scientific and practical importance. With increasing of the order of nonlinearity, the conversion efficiency strongly falls down. That is why, o

Copper lasers have for a long time been used in spectroscopy to generate tunable narrowband light in the range 580-750 nm by pumping a dye laser and 750-1000 nm by pumping a titanium sapphire laser. The generation of high UV powers (-500 mW) in the r

A number of resonances have been observed in the excitation spectrum of the uv resonance lines of sodium. The mechanism proposed includes absorption by molecular states, energy transfer to excited atomic levels and four-wave parametric generation enh
