The depth of mass ablation in planar Sn targets during the interaction with a pulsed Nd:YAG laser was investigated. The pulse duration and laser spot size were fixed, and the laser energy was varied to achieve laser intensities from approximately 10 to 10 W/cm, which is relevant to the extreme ultraviolet (EUV) lithography application. The ablation depth was measured by irradiating layered targ...

statement of problem: the achievement of a good and durable dentin/composite resin bond is an important task in restorative dentistry. the application of acid conditioners and dentin bonding agents is an accepted method to enhance this bond strength. pretreating of dentin surface by laser irradiation seems to be a supplemental way to obtain better results, since lased dentin is more roughened a...

However, the theoretical proof of the attraction possibility was given by Kazantsev and Sokolov for interaction of classical relativistic electrons in the field of a plane wave [5]. It is worth noting the work [6]. It is very important to point out, that attraction of classical electrons in the ...

in recent years an abundance of theoretical and experimental works concerning infrared photochemistry has been accomplished. it coincides with the possibility of using intense infrared laser radiation to dissociate molecules in order to induce a selective laser photochemistry. however, the major fraction of these works is concerned with the pulsed photolysis in order to minimize the temperature...

Correspondence Intralenticular haemorrhage complicating pulsed laser iridotomy SIR, The pulsed laser has recently been described as a 'non-surgical' means of producing a peripheral iridotomy. The complications of this procedure have been reviewed' and include iritis, pigment dispersion, haemorrhage, transient elevation of intraocular pressure, corneal or lens damage, lack of patency of the irid...

of aluminum oxide, that emitted a deep red-colored beam. After this invention, dental researchers started investigating the various potentials of lasers. In 1965, Stern and Sognnaes reported that a ruby laser could vaporize enamel and had thermal effects on the dental pulp. In 1970’s, researchers began to find the clinical oral soft tissue uses of medical CO2 and neodymiumdoped:yttrium aluminum...
