Tetragonal NaT(WO4)2, T= trivalent Y, La, Gd and Lu, single crystals doped with Yb3+ or Tm3+ have shown efficient room temperature laser operation at λ≈1.05 μm and λ≈1.95 μm, respectively. The broad bandwidth of the optical transitions of these lanthanides is of particular interest for diode-laser-pumped tunable and mode-locked femtosecond lasers. The present knowledge about these crystals and their applications as solid state lasers is overviewed. Results of new material preparation directions to produce epilayers and nano-, micro-particles of these compounds are described.
