Measurement of Mirror Birefringence at the Sub-Ppm Level: Proposed Application to a Test of QED
نویسندگان
چکیده
We present detailed considerations on the achievable sensitivity in the measurement of birefringence using a high finesse optical cavity, emphasizing techniques based on frequency metrology. Alternative approaches of laser locking and cavity measurement techniques are discussed and demonstrated. High-precision measurements of the cavity mirror birefringence have led to the interesting observations of photorefractive activities on mirror surfaces.

Mirror Birefringcncc in a Fabry-Perot Cavity and the Detection of Vacuum Birefringence in a Magnetic Field
Wc discuss the effect of mirror birefringence in two optical schemes designed to detect the quantum-electrodynamics (QED) predictions of vacuum bircfringence under the influence of a strong magnetic field, B. Both schemes make t]sc of a high finesse Fabry-Perot cavity (F-P) to incre:ise the average path length of the light in the magnetic field. The first schcmc,)wc called the frequency scheme,...
متن کاملOptical bistability induced by mirror absorption: measurement of absorption coefficients at the sub-ppm level.
We have observed optical bistability caused by absorption-induced thermal expansion of mirrors forming a Fabry-Perot interferometer. From the resulting anomalous transmission line shapes, absorption coefficients of the mirror coatings as low as 0.2parts in 10(6) (ppm) have been successfully measured.

A pot experiment was conducted in a completely randomized design with five treatment and five replication, in each replication were 6 plants used. The study of zinc sulphate (ZnSO4) application (20 and 40 ppm) and Salicylic acid (SA) application (50 and 150 ppm) was compared to the control (distillated water) on growth and flowering Petunia hybrid. For each plant was used 10...

متن کاملO-11: Zona Pellucida Birefringence and Meiotic Spindle Visualization of Human Oocytes Are Not Influenced by In Vitro Maturation Technology
Background: In vitro maturation (IVM) is a promising treatment option for certain infertile women. Nowadays, with the aid of the Polscope, it has become possible to evaluate zona pellucida (ZP) and spindle as parameters of oocyte quality. The goal was to investigate the relationship between the presence of the meiotic spindle and ZP birefringence with morphology of the in vivo and in vitro matu...
