Enhanced photorefractive effect in SBN:60:Cr and SBN.60:Rh with external dc fields

Annual Meeting Optical Society of America, 1989
A major thrust of photorefractive materials research has been to increase the coupling constant Γ and speed up response time. Previous two-beam coupling experiments using SBN:60 have shown that the space charge field Esc, and therefore the coupling constant, can be increased to some degree by optimizing the characteristic fields En and Ed.1,2 However ...

Shallow traps in doped SBN crystals

Optical Materials, 1995
Abstract Three different physical effects resulting from shallow traps in SBN crystals are demonstrated experimentally. They are: (i) intensity induced deformation of the dependence of the two-wave gain on the angle between the waves, (ii) two temporal scales of grating dynamics at CW illumination and (iii) a dark grating decay which depends on the ...

Holographic recording In photorefractive SBN fibers

Annual Meeting Optical Society of America, 1988
SBN is an attractive photorefractive medium, which is difficult to grow in large bulk sizes of good optical quality. Alternatively, at Stanford we grew SBN fibers of lengths exceeding 10 cm and with a diameter of <160 μm. These fibers offer a unique environment for carrying out phase conjugation experiments, such as holographic data storage, self ...

Selbstfokussierung in BaTiO3 und SBN

2006
Es konnte nachgewiesen werden, dass in Bariumtitanat und SBN auch ohne ein äußeres elektrisches Feld ein Selbstfokussierungseffekt auftritt. Dazu wurden Untersuchungen in 19 Bariumtitanatkristallen und einem SBN:60 Kristall durchgeführt, wobei es zwischen 4 Minuten und 30 Minuten dauerte bis der Strahldurchmesser auf der Kristallaustrittsfläche einen ...
