Optical activity measurements in the photorefractive Bi12TiO20 single crystal fibers

The characteristics of high-quality Yb:YAG single crystal fibers grown by a LHPG method and the effects of their discoloration

“…Therefore, crystal bers with higher thermal conductivity, better mechanical properties and higher damage thresholds can be used to promote the development of next-generation high-power lasers. [9][10][11][12][13][14][15][16][17] Yttrium aluminium garnet (YAG) belongs to a cubic system, with the unit cell parameter a ¼ 12.0089Å. YAG crystals have good physical and chemical stabilities and have been widely used in solid-state lasers.…”

The fabrication of planar waveguides on Bi12TiO20 crystals by oxygen and helium ion implantation

“…This suits the wavelengths of the low-cost and commonly used He-Ne and diode lasers. Furthermore, the optical activity in BTO is considerably lower than in Bi 12 SiO 20 (BSO) and Bi 12 GeO 20 (BGO) [5], making them appropriate media for optical spatial soliton propagation, waveguides and fibre-like crystals [6,7].…”

Optical Activity Measurements by Interferometry-Diffraction Technique: Test with BSO Crystals

“…Different techniques have been proposed to study this optical phenomenon [1][2][3][4][5][6][7][8][9][10][11][12][13]. As an interferometry technique have been reported vibrational circular dichroism measurements by optical subtraction FT-IR spectrometry [2].…”

“…The proposed technique consists of a Mach-Zehnder interferometer coupled with an optical Fourier processor 2F. Three samples of photorefractive BSO crystals were used in tests [7][8][9][10][11][12][13]. These crystals exhibit Biot dispersion.…”
