Lasers with emission wavelengths of 1.5 μm are suitable for the eye-safe band and
transparency region of the atmosphere. During extremely bad weather conditions, the …

The optical properties and functionality of air-stable PbSe/PbS core− shell and PbSe/PbSe x
S1-x core-alloyed shell nanocrystal quantum dots (NQDs) are presented. These NQDs …

In this topic review the results of the X-band electron paramagnetic resonance (EPR)
measurements of Mn, Co, Cr, Fe ions in YAlO 3 (YAP) crystals and Fe ions in LiNbO 3 (LNO) …

Excited state absorption spectra (ESA) of the LiGa5O8 (LGO), MgAl2O4 (MALO) and
LaMgAl11O19 (LMA) crystals doped with the tetrahedral Co2+ ion were studied under …

The sol-gel synthesis of ZnAl 2 O 4 ceramic powders from alkoxide and acetate sources of
metals, as well as the microstucture and the hardness of the hot-pressed ZnAl 2 O 4 …

We report on a 2ω-OPSL-pumped passively Q-switched Pr^ 3+: LiYF_4 laser operating at
the wavelengths of 523, 607, and 640 nm. For this, we utilized a Co^ 2+-doped MgAl_2O_4 …

We report for the first time, to the best of our knowledge, on a diode-pumped passively Q-
switched Er, Yb: GdAl_3 (BO_3) _4 laser. By using a Co^ 2+: MgAl_2O_4 crystal as a …

Transparent cobalt-doped zinc aluminate spinel (gahnite), Co 2+: ZnAl 2 O 4, ceramics were
fabricated by hot pressing of (Zn, Co) Al 2 O 4/ZnF 2 nanopowders at 1520° C for 4 h. A …

Upconversion luminescence of lanthanide ion doped nanocrystals under ultrashort laser
pulse excitation can find significant applications in areas like super-resolution nonlinear …

Abstract Ti and Mn‐doped MgAl2O4 spinel have been successfully grown by the micro‐
pulling‐down method and spectroscopic properties have been investigated in view of the …
