Description
Summary:We report here, for the first time, diode-pumped continuous-wave laser operation of Nd:LuYAG (LYAG) and Nd:LuGdAG (LGAG) mixed crystals around 1.83 <italic>&#x03BC;</italic>m. Cooling the laser samples down to about 6&#x00A0;&#x00B0;C, output powers of about 0.56 and 0.46&#x00A0;W with slope efficiencies of about 5.5&#x0025; and 5.6&#x0025; can be achieved, respectively, for the two crystals. These <inline-formula><tex-math notation="LaTeX"> ${\rm{Nd}}^{3+ }{- \rm{doped}}$</tex-math></inline-formula> garnet mixed crystals, like single crystal Nd:YAG, are believed to be the potential for laser generation at the important 1.83-<italic>&#x03BC;</italic>m near-infrared wavelength domain.
