On the effect of surface rippling on the generation of harmonics in laser plasmas
Applied Physics B, 2005Experiments were carried out using a tightly focused, prepulse-free KrF laser of 700 fs pulse duration. Harmonics up to 20 eV were generated at an intensity of 1.5×1017 W/cm2 from the plasma on the surface of solid targets. The observation of diffuse harmonics propagation for intensities above 1016 W/cm2 and the fact that polarization of the harmonics ...

Surface waves in laser-produced plasma double layers
IEEE Transactions on Plasma Science, 1989The surface-tension pressure for a charged double layer is calculated. This result is used to derive the dispersion relation for surface waves. The stability criterion defines stable surface waves with wavelength lambda /sub sw/ >

The Formation of Ring Shaped Laser Plasmas on a Metal Surface
AIP Conference Proceedings, 2006A method to produce ring plasmas on a metal surface is presented. The ring plasma is produced by focusing a laser pulse into an annular shape. This is achieved by using a combination of a converging lens and an axicon. The axicon is a rotationally symmetric prism.

Laser plasma effects on surface damage characteristics of silicon
SPIE Proceedings, 2011Silicon is a key material to electro-photonic detectors, which makes the studies of laser induced damage of silicon significantly important in laser detecting and military applications. The damage characters of silicon under high-intensity nanosecond laser pulses have been investigated in this paper.

Nondestructive laser-induced plasma formation at a target surface
Technical Physics Letters, 2001The parameters of ultrashort laser pulses and the thermal characteristics of a metal target were determined, which provide that the laser-induced plasma formation at the target surface does not lead to damage of the metal surface. The results of calculations are compared to experimental data.

Pulsed Laser Initiation of Surface Plasma on Metal Mirrors
1981Plasma formation at the surface of a metal mirror under intense pulsed laser irradiation in an ambient atmosphere usually leads to enhanced thermal and mechanical coupling with consequently increased surface damage. Exo-electron emission associated with plastic micro-yielding of the metal surface under thermomechanical stress induced by ...
