Device for transformation of concentrated solar energy

A device for transformation of concentrated solar energy, comprising:

• a laser device comprising:
• an active medium for total or partial absorption of solar spectrum and for formation of a laser beam;
• a first reflecting mirror adapted for entry of a concentrated incident light beam;
• a second reflecting mirror adapted for an outlet of the laser beam, which is reflective in an interval of absorption wavelengths of the active medium and transparent in wavelengths different to the interval of absorption wavelength and at the outlet of the laser beam;
• an initial coating of a nucleus which has a refraction index lower than that of the nucleus so that the laser beam generated is transmissible within an interface of the nucleus and the initial coating in single mode;
• and
• a second coating;
• wherein with the first reflecting mirror is reflective on the outlet wavelength of the laser beam and the second reflecting mirror is partially reflective on the outlet wavelength of the laser beam;
• wherein the active medium is located between the first and the second reflecting mirrors which are arranged facing each other;
• wherein the active medium is a nucleus that includes at least one section with substances configured, totally or partially, to absorb the solar spectrum and generate the laser beam and the active medium is situated longitudinally with respect to the laser device,
• wherein the first reflecting mirror is transparent to all wavelengths of the solar spectrum,
• wherein the second coating has a refraction index lower than the first coating such that the concentrated incident light beam is transmissible within an interface of the first and second coatings by total internal reflection, and
• the solar energy transformation device further comprising a photovoltaic cell in series with the laser device and that is situated before the laser device.
