“…Crystals which display large first and second order hyperpolarizability are the reason for getting high nonlinear response [1][2][3][4]. Organic crystals have an eye of attraction because of their promising high nonlinear optical susceptibilities with less time of optical response and flexibility to fabricate the compounds.…”

CYHMH crystal was grown using solution growth technique The crystal corresponds to monoclinic structural system with C12/C1 space group (centrosymmetric in nature) and The final cell constants values are a = 24.109 (2) Å, b = 5.5157(4) Å, c = 18.6739(14) Å, β = 110.807(2)°, volume = 2321.2(2) Å. Mechanical studies were measured using Vicker’s hardness tester and n was 1.40, therefore the CYHMH crystals comes under hard materials category. The elastic toughness (stiffness) decreased with increases in applied load. Dielectric permittivity of CYHMH and loss factor were calculated as a function of log frequency. While increasing the temperature the dielectric parameters (dielectric constant, loss, AC conductivity) also increased. The energy required to activate the conductivity were also calculated for higher frequency region.

“…Previous researches showed that the family of RECa 4 O(BO 3 ) 3 (RECOB, RE = Y, Gd, La, Tm, Sm, and Nd) crystals were found to be melted congruently and could be grown into a large-size by the Czochralski (Cz) pulling method [14][15][16][17]. More meaningful, the substitutional solid solutions of RE1 x RE2 1−x COB (RE1 = Y, RE2 = Gd, and La) crystals were found to have compositional uniformity along the growth direction [18][19][20]. Furuya et al had found that the ratio of a/b and a/c for Gd x Y 1−x COB crystals were linear variation with the changing of chemical composition x, and their A-NCPM third-harmonic-generation (THG) wavelengths were tunable to be around 1064 nm by keeping the variable x = 0.28, in 1999 [21].…”

The angular non-critical phase-matching (A-NCPM) second-harmonic-generation (SHG) properties of RE1xRE21−xCOB (RE1, RE2 = Y, Gd, La, Tm, Sm, and Nd) type mixed crystals including NCPM wavelength and conversion efficiency were detailedly investigated. Theoretical calculations manifest that the A-NCPM SHG scope of these crystals is 0.72~1.42 µm, and in experiments, the A-NCPM SHG waveband of 0.72~1.25 µm has been realized, by changing the ratio of the rare-earth elements RE1 and RE2 in RE1xRE21−xCOB crystals. Comparing to the temperature-dependent A-NCPM SHG of 0.95~1.34 µm in LiB3O5 (LBO) crystal, the composition-dependent A-NCPM SHG of 0.72~0.95 µm in RE1xRE21−xCOB type crystals is unique and has special significance for the frequency conversion of Ti:Sapphire lasers. Relationships between the birefringence and radius of rare-earth ion RE3+ in RE1xRE21−xCOB mixed crystals were discussed. Aiming for the A-NCPM SHG of 0.72~1.42 µm, we supply a clear, completed, and optimized solution on how to select the compositions of RE1xRE21−xCOB mixed crystals. Under focusing light beam conditions, high efficient A-NCPM SHG for both OPO and Ti:sapphire lasers were realized experimentally by using long Y- and Z-cut RE1xRE21−xCOB crystal samples.
