The invention relates to a device for cooling slots in a turbomachine rotor disk, comprising a rotor disk having a plurality of slots and a flange. The substrate has an opening and a plurality of grooves arranged around a periphery of the opening. The generated identifiers are used for detecting identical digital data or to determine inexact copies of digital data. The layout preferably is determined through communication with the printer and the target device so as to negotiate the layout. More specifically, this invention relates to such a means and method where there is an enhanced translation memory comprising an alignment function. By inducing third-order dispersion in fiber amplifiers via self-phase modulation, the third-order chromatic dispersion from bulk grating pulse compressors can be compensated and the pulse quality of hybrid fiberbulk chirped pulse amplification systems can be improved.
