Abstract

We report on the use of high temperature superconductor material for fabricating of a resonator of a far-infrared solid state laser. In our experiment the active medium consisted of a p-germanium crystal at 4.2 K in crossed electric and magnetic fields. We used a SrTiO₃ plate as highly reflecting mirror and a YBa₂Cu₃O_7-δ thin film on MgO plate as output coupling mirror. The spectra of the laser with the superconducting mirror was measured. We demonstrate also highly reproducible operation of the laser.
