Project summary

The Project objective is design and creation of the high-power solid-state lasers, based of the pulse compression, for the purposes of nonlinear and laser plasma optics, X-ray microscopy, lithography, production of amorphous diamond and inertial confinement fusion.

The tasks of the Project:

In the course of the Project fulfillment there will be carried out the mastering in practice of the new architecture for the high-power pulsed or pulse-repetitive solid-state lasers for various applications, providing some advantages in comparison with the common type lasers. In particular, high efficiency, combined with the significantly reduced cost of the pulse-repetitive nano- and subnano-second lasers, based on the pulse compression will make it possible to use such a sources in industry for the purposes of X-ray microscopy, lithography, amorphous diamonds production etc.

Elaborated during the Project fulfillment technologies for fabrication of the new optical materials (crystals, glasses, coatings), new optical components (amplifiers, compressors, phase conjugation mirrors etc.) as well as methods of intense pulse generation, methods and software for numerical calculations, may be used in various related fields of science and engineering.

Supposed results:

1. Elaboration of the new optical methods and schemes of the intense laser pulses generation with the duration 0.5-5 ns and repetition rate up to 100 Hz, improving significantly the parameters of the solid-state lasers with the simultaneous cost reducing.

2. Creation of the efficient solid-state lasers with the high radiation power (up to 3-5 TW) on the base of SBS-compression of long pulses.

3. Elaboration of the theory, analytical models and numerical software for the design of the laser systems and their applications.

4. Elaboration of laser schematics, based on SBS-compression use for the purposes of X-ray microscopy, lithography, amorphous diamond production, confinement fusion etc.
