Filament-induced birefringence in Argon

Femtosecond filament induced birefringence in argon and in air: Ultrafast refractive index change

Thermal-birefringence-induced depolarization in Nd:YAG ceramics.

The thermal-birefringence effect in Nd(3+) -doped YAG ceramics has been investigated. The amount of depolarization induced by thermal birefringence in Nd:YAG ceramics is nearly the same as that in (111)-cut single crystals at the same Nd(3+) concentration. However, depolarization becomes larger as the Nd(3+) concentration increases, even at the same absorbed pump power.

improved laser induced birefringence in highly doped optical polymers

application of polymers in novel and advanced scientific technologies is increasingly expanding. in this regard, optical polymers among different materials have found a special and unique position. a novel dye doped polymer thin film was prepared by taking advantage of dye molecules' interaction with the host environment. this sample, like self-assembled structures, makes use of this inter...

Geometric phase via stress induced birefringence

Optical components exploiting Pancharatnam-Berry phase are implemented by harnessing laser induced stress birefringence. Beam converters for obtaining beams with orbital angular momentum are demonstrated in glass and crystalline materials using this technique.

Transient electric birefringence study of intermediate filament formation from vimentin and glial fibrillary acidic protein.

Mg2+-induced polymerization of type III intermediate filament proteins vimentin and glial fibrillary acidic protein was studied by transient electric birefringence. In the absence of MgCl2 we found a net permanent dipole moment, approximately 45-nm-long dimers for vimentin, approximately 65-nm-long tetramers, hexamers, and possibly octamers for both proteins, and 100-nm aggregates for glial fib...
