“…[93][94][95][96][97][98] The properties of LN doped with optical damage resistant ions were first summarized in a review paper 10 and later in a book by Volk et al 99 Recently, Kong et al 100 reviewed advances in the photorefraction of doped LN, focusing on tetra-, penta-, and hexavalent ions, including doubly-and even triply-doped crystals. They concluded that LN triply doped by Zr, Fe, and Mn shows excellent non-volatile holographic storage properties, and V and Mo single-doped LN have fast response and multi-wavelength storage characteristics.…”

“…44,45,47 In addition, the increase in the valence of the dopant decreases the threshold. [94][95][96][97][98] In general, the incorporation of ODR ions reduces the amount of antisite Nb Li in the lattice. In nearly stoichiometric LN crystals where the Nb Li concentration is almost zero, the threshold value of the dopant concentration can be lower than 0.2 mol.…”

Owing to the extraordinary richness of its physical properties, congruent lithium niobate has attracted multidecade-long interest both for fundamental science and applications. The combination of ferro-, pyro-, and piezoelectric properties with large electro-optic, acousto-optic, and photoelastic coefficients as well as the strong photorefractive and photovoltaic effects offers a great potential for applications in modern optics. To provide powerful optical components in high energy laser applications, tailoring of key material parameters, especially stoichiometry, is required. This paper reviews the state of the art of growing large stoichiometric LiNbO 3 (sLN) crystals, in particular, the defect engineering of pure and doped sLN with emphasis on optical damage resistant (ODR) dopants (e.g., Mg, Zn, In, Sc, Hf, Zr, Sn). The discussion is focused on crystals grown by the high temperature top seeded solution growth (HTTSSG) technique using alkali oxide fluxing agents. Based on high-temperature phase equilibria studies of the Li 2 O-Nb 2 O 5 -X 2 O ternary systems (X ¼ Na, K, Rb, Cs), the impact of alkali homologue additives on the stoichiometry of the lithium niobate phase will be analyzed, together with a summary of the ultraviolet, infrared, and far-infrared absorption spectroscopic methods developed to characterize the composition of the crystals. It will be shown that using HTTSSG from K 2 O containing flux, crystals closest to the stoichiometric composition can be grown characterized by a UV-edge position of at about 302 nm and a single narrow hydroxyl band in the IR with a linewidth of less than 3 cm À1 at 300 K. The threshold concentrations for ODR dopants depend on crystal stoichiometry and the valence of the dopants; Raman spectra, hydroxyl vibration spectra, and Z-scan measurements prove to be useful to distinguish crystals below and above the photorefractive threshold. Crystals just above the threshold are preferred for most nonlinear optical applications apart holography and have the additional advantage to minimize the absorption even in the far-infrared (THz) range. The review also provides a discussion on the progress made in the characterization of non-stoichiometry related intrinsic and extrinsic defect structures in doped LN crystals, with emphasis on ODR-ion-doped and/or closely stoichiometric systems, based on both spectroscopic measurements and theoretical modelling, including the results of first principles quantum mechanical calculations on hydroxyl defects. It will also be shown that new perspective applications, e.g., the generation of high energy THz pulses with energies on the tens-of-mJ scale, are feasible with ODR-doped sLN crystals if optimal conditions, including the contact grating technique, are applied.

“…Platinum cylinder was used as an after-heater to ensure a controlled post growth cooling of the crystal. The post growth cooling was maintained at a rate [10][11][12][13][14][15] o C/h initially up to 800 o C, and thereafter 20-25 o C/h to room temperature [16]. Different undoped and doped crystals were grown successfully.…”

“…When LiNbO 3 devices are used at high laser intensity, their performance is severely limited by the optical damage effect, which induces birefringence change and deforms the laser beams. Some damage resistant impurities have been reported, such as divalent (Mg 2+ [12], Zn 2+ [13]) and trivalent (In 3+ [14], and Sc 3+ [15]) impurities, which lead to a strong decrease of the photo damage in LiNbO 3 and have been receiving a lot of interest. In this paper we have studied the effect of doping and co-doping on lithium niobate crystal lattice using powder x-ray diffraction (XRD) and high resolution x-ray diffraction (HRXRD).…”

Undoped and doped LiNbO 3 single crystals were grown by Czochralski technique. Comparative studies on these undoped, Cr doped, Mg doped, Mg:Cr codoped and Mg:Nd codoped LiNbO 3 single crystals were carried out. Phase identification was done using powder XRD technique. The effect of doping and co-doping on crystalline perfection of these crystals was monitored using high resolution x-ray diffraction (HRXRD) technique. The diffraction curves (DCs) were recorded in symmetrical Bragg geometry for (006) diffracting planes using MoK 1 radiation.

“…The most efficient method is doping with the group of impurities termed "optical-damage resistant" ("ODRI" below); the development of this approach can be found, e.g., in [1]. Presently, this group includes reliably seven ions, namely the divalent Mg [2] and Zn [3], trivalent In [4] and Sc [5] and tetravalent Hf [6], Zr [7] and Sn [8] (this numbering refers to the order of publications).…”

Abstract:The lattice parameters in optical damage resistant crystal LiNbO 3 -In were measured for the first time using the X-ray powder method with an internal standard, which provides a high accuracy of the results. The lattice parameters vs. In concentration were obtained in the concentration range from 0.24 to 3.2 at % In in the crystal. The results are discussed in the framework of currently accepted model of the LiNbO 3 intrinsic defect structure.
