Spectroscopic investigation of new BIS(phthalocyaninato)lanthanide complexes for optical limitation of powerful laser radiation

AbstractThe paper presents a general theoretical framework and related Monte Carlo simulation of novel type of the X-ray sources based on relativistic Thomson scattering of powerful laser radiation. Special attention is paid to the linac X-ray generators by way of two examples: conceptual design for production of 12.4 keV photons and presently operating X-ray source of 29.4 keV photons. Our analysis shows that state-of-the-art laser and accelerator technologies enable to build up a compact linac-based Thomson source for the same X-ray imaging and diffraction experiments as in using of a large-scale X-ray radiation facility like a synchrotron or Thomson generator based on electron storage ring.

Illumination Mode

A high-efficiency photovoltaic module optimized for converting the monochromatic radiation with a wavelength of 809-850 nm is presented. The module comprises four photovoltaic converters with the total area of 16 cm2, which can provide the operating voltage of 4 V in the case of laser power greater than 1 W. The laser power converters are developed on the basis of AlGaAs/GaAs structures grown by LPE and MOVPE. When operating in the uniform illumination mode, the efficiency of the photovoltaic module is found to exceed 60% for the powerful laser radiation (6.2 W).
