Crystal Growth and Optical Characterization of Rare-Earth (Re) Calcium Oxyborate ReCa ₄O(BO ₃) ₃ (Re = Y or Gd) as New Nonlinear Optical Material

Abstract

We report on the growth of GdCa4O(BO3)3 (GdCOB) and YCa4O(BO3)3 (YCOB) crystals and their characterization as new nonlinear optical materials. The crystals with good optical quality were grown by the Czochralski method. YCOB, the characteristics of which has not previously been reported to our knowledge, has a larger temperature acceptance bandwidth than that of GdCOB, and third harmonic generation of a Nd:YAG laser in this crystal was demonstrated.

Growth and Characterisation of new Semi Organic Crystal Bisthiourea Calciumacetate

“…New nonlinear optical (NLO) frequency conversion materials have a significant impact on laser technology, optical communication and optical data storage. Second order nonlinear optical (SONLO) materials have recently attracted much attention because of their potential applications in emerging optoelectronic technologies [1][2][3][4][5].Thus the search for new NLO materials has been the subject of intense research. Materials with large second-order nonlinearities, large optical transmission window and stable physicochemical performance are needed for various applications [6].…”

Thermal-Diffusivity Dependence on Temperature of Gadolinium Calcium Oxoborate Single Crystals

“…Among a wide group of non-linear optical crystals, gadolinium calcium oxoborate GdCa 4 Pure and rare-earth ion-doped GdCOB crystals possess many interesting physical properties such as a high-nonlinear coefficient, high-damage threshold, high-optical gain at 1.06 µm, and low self-absorption at the second-harmonic wavelength [2]. They find applications as efficient crystals for frequency conversion and self-frequency doubling laser [3].…”

Czochralski growth and spectroscopic investigations of Yb3+, La3+:Na2SO4(I) and Nd3+:Na2SO4(I)

“…In this respect Na 2 SO 4 (I) shows a lower chemical stability than other materials mentioned above. [6][7][8][9][10][11][12] …”
