Zero-birefringence pressure-sensitive adhesives
We have developed zero-birefringence pressure-sensitive adhesives (PSAs) that exhibit almost no birefringence at any orientation of polymer chains. To evaluate the birefringence of PSAs quantitatively, we report a novel birefringence-measurement method ...

Optical rheology of porcine sclera by birefringence imaging. [PDF]
To investigate a relationship between birefringence and elasticity of porcine sclera ex vivo using polarization-sensitive optical coherence tomography (PS-OCT).Elastic parameters and birefringence of 19 porcine eyes were measured.

Acoustic Birefringence Changes in the Base Metal and Heat Affected Zone of ASTM 1020 Steel under Plastic Deformation and Fatigue [PDF]
This paper deals with metallographic studies and ultrasonic investigations of acoustic birefringence in the base metal and heat affected zone of welded specimens of ASTM 1020 steel under uniaxial tension and low-cycle fatigue. We examined microstructural

Visible to mid-infrared giant in-plane optical anisotropy in ternary van der Waals crystals
Birefringence is at the heart of photonic applications. Layered van der Waals materials inherently support considerable out-of-plane birefringence.

Laser-stimulated birefringence of Ga2O3-La2S2.95Se0.05 glasses for optical recording of information
We show an opportunity to change the birefringence of Ga2O3 – La2S2.95Se0.05 glasses doped by Er3+ and La3+ ions at λ = 1150 nm wavelength of cw He-Ne laser under illumination of the femtosecond laser.

Birefringence-Managed Normal-Dispersion Fiber Laser Delivering Energy-Tunable Chirp-Free Solitons
Chirp-free solitons have been mainly achieved with anomalous-dispersion fiber lasers by the balance of dispersive and nonlinear effects, and the single-pulse energy is constrained within a relatively small range.
