Growth and properties of Tm: YAG crystals

Dopant segregation in rare earth doped lutetium aluminum garnet single crystals grown by the micro-pulling down method

“…6. All of the sharp absorption peaks observed in the spectrum can be attributed to transitions form the ground level of 3 H 6 to higher levels of Tm 3 þ [11,13]. Unlike the absorption spectra of the Nd:LuAG crystal, the absorption spectra of the Tm:LuAG crystal at the central region and at the rim are almost same.…”

Analysis of influence of Yb concentration on thermal, elastic, optical and lattice parameters in YAG single crystal

“…It reveals a low thermal load, long upper state lifetime and high thermal conductivity [2]. Tm 3+ doped YAG is applied in diodepumped solid state lasers (DPSSL) operating in range from 1.0 m to 3.0 m [3]. This range encompasses a several important molecular absorption bands like carbon dioxide and strong water vapor bands.…”

Optical absorption and spectroscopic characteristics of Tm3+ ions doped NaY(MoO4)2 crystal

“…The maximum absorption cross-section for polarization was found to be 2.63 × 10 −20 cm 2 at 796 nm with 26 nm bandwidth (full width at half maximum), and 1.69 × 10 −20 cm 2 at 796 nm with 37 nm bandwidth for polarization. These values are much higher than that of YAG (the absorption cross-section is 6.3 × 10 −21 cm 2 , FWHM is 11 nm at 781 nm) [14].…”
