Smoothing and stochastic pulsation at high power laser-plasma interaction

Treatment of lentigines by a novel high power diode laser at 755 nm: a case report

The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...

Laminar shocks in high power laser plasma interactions

High-Power Laser-Plasma Chemistry in Planetary Atmospheres

Currently generally accepted opinion considering Earth’s early atmosphere as a mildly reduced gas mixture of molecular gases represents a crucial difficulty for the classical Miller's experiments carried out originally in a strongly reducing gaseous mixture. In the weakly reducing environment they give a poor yield of amino acids and other compounds of relevance to the chemical evolution. In ou...

High harmonic generation in relativistic laser–plasma interaction

High harmonics generated due to the scattering of relativistic electrons from high intensity laser light is studied. The experiments are carried out with an Nd:Glass laser system with a peak intensity of 2310 W cm in underdense plasma. It is shown that, at high intensities, when the normalized electric field approaches unity, in addition to the conventional atomic harmonics from bound electrons...

Laser-produced plasma-wall interaction

Jets of laser–generated plasma represent a flexible and well-defined model environment for investigation of plasma interactions with solid surfaces (walls). The pilot experiments carried out on the iodine laser system (5–200 J, 0.44 mm, 0.25–0.3 ns, ,1 10 W/cm) at the PALS Research Centre in Prague are reported. Modification of macroscopic characteristics of the Al plasma jets produced at laser...
