The effect of Cr doping on optical and photoluminescence properties of LiNbO3 crystals

Growth and properties of Ru-doped lithium niobate crystal

“…One of the most effective methods for improvement is to add a small amount of dopant into the congruent LiNbO 3 melt composition. A variety of dopants have been used in the past, such as Mg, Zn, Sc, and In (for reducing optical damage) [2][3][4][5], Nd, Er, Yb and Cr (for laser-host applications) [6,7], and Fe, Mn, Rh, Cu and Ce (for high-density holographic data storage) [8][9][10][11]. The material and optical properties of the crystal are also changed by the amount and type of dopant added.…”

Spectroscopy of YAl3(BO3)4:Cr3+crystals following first principles and crystal field calculations

“…Second harmonic generation in the UV region (375 nm) was obtained by a Cr 3+ :YAB Cr 3+ :YAB crystal and Cr 3+ :YGAB crystal have potential as new optically operated materials [9].…”

Optimisation of chromium doping in LiNbO3 single crystals

“…However, the EDAX from 0.1 mol% Cr doped crystals does not show a peak for chromium, which is expected due to the very low level of doping. The Cr 3+ ions are expected to occupy Li sites and /or Li vacancy sites [6]. Laser damage threshold on these grown crystals was measured, and it was found to be about 70-80 MW/cm 2 for a 18 ns, 17 mJ Nd:YAG laser.…”
