| Popis: | A laser-quality anisotropic Z n S : C r 2 + element was obtained using prolonged hot isostatic pressing at high temperature. Lasing centered at a wavelength of 2.45 µm was obtained with longitudinal pumping at a wavelength of 1.94 µm. The short-cavity laser slope efficiency with respect to the absorbed power was about 78%. The lasing wavelength was continuously tuned in the range of 2.35–2.52 µm by rotating the Brewster active element around the normal to its surface. |
