Abstract:
1. A laser device for emission of waves in a frequency range in the terahertz range, the laser device comprising: a waveguide extending longitudinally according to an axis A-A′, the waveguide comprising a proximal end and a distal end; a superconducting coil coaxial to the waveguide and arranged at the level of the proximal end of the waveguide; a p-Ge crystal of p-doped germanium arranged inside the coil such that the windings of the superconducting coil at least partially enclose the p-Ge crystal; cooling means containing coolant in the liquid state, the superconducting coil and the p-Ge crystal being arranged in the cooling means and the waveguide extending partially to the exterior of the cooling means; means for eliminating coolant in the liquid state in the waveguide, the means comprising two windows transparent to light radiation in the terahertz range at the level of the proximal and distal ends of the waveguide.
