Optical spectra, energy levels and branching ratios of trivalent dysprosium-doped yttrium scandium gallium garnet

Optical spectroscopy of NaLa(WO4)2:Dy3+ single crystal

“…The raw materials of NLW:Dy 3+ were synthesized by means of solid-state reaction. The chemicals used were Na 2 CO 3 (99.95%), WO 3 (99.99%). The chemical reaction is as follows:…”

“…Until then, laser action in inorganic solids activated with Dy 3+ ions had been observed only in the NIR (1.35 and 3 m) [2] in the case of fluoride hosts. Moreover, Dy 3+ -doped garnets have been indicated as potential saturable absorbers in the 2.8 m region [3]. As a consequence, the interest in the optical properties of Dy 3+ -doped oxides is considerably increasing currently [4][5][6][7][8].…”

Optical transitions and absorption intensities of Dy3+ (4f9) in YSGG laser host

“…Although spectroscopic and laser studies have been performed extensively on most of the rare earth (RE) ions, there have been, to the best of our knowledge, only limited investigations on trivalent dysprosium ions (Dy 3+ ) doped in either glasses or crystalline hosts [1][2][3][4][5][6]. The lack of widespread investigations on Dy 3+ is due to the fact that its many excited states are candidates for excited state absorption (ESA).…”

Spectroscopic investigation of Dy3+-doped Li2Gd4(MoO4)7 crystal for potential application in solid-state yellow laser

“…In recent years, there has been renewed interest in optical materials doped with Dy 3+ ions due to the perspective of developing new laser media for the near-infrared (NIR) and visible regions, or NIR saturable absorber for Q-switch devices [1][2][3][4]. As we all known, there is still a blank region between 550 and 650 nm, which cannot be covered even with the Ti:Al 2 O 3 laser and its second harmonic, while the yellow laser emission has potential application in a variety of scientific and technological fields, such as military, telecommunication, and commercial.…”
