Abstract:

The emission of harmonic radiation by an electron oscillating anharmonically in a linearly polarized plane ultra-intense laser field is studied. The electron is described as a classical relativistic particle with a magnetic moment in order to include the spin-laser interaction. In contrast to ordinary Maxwell dynamics the motion can become three-dimensional depending on the orientation of the spin. Additional harmonics are visible in the direction of the electric field of the laser where no harmonics of polarization along the magnetic-field direction are to be expected.

What is OpenURL?

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access. An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.

If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
