标题： Generation of Polarization Squeezing with Periodically Poled KTP at 1064 nm

摘要： 我们报告了基于周期极化KTP晶体（PPKTP）的一型光学参量放大器（OPA）直接产生1064 nm波长偏振压缩的实验演示。 偏振压缩态的正交偏振模式均由OPA腔模式定义，并且由PPKTP晶体引起的双折射通过第二个但非活性的PPKTP晶体得到补偿。 观察到斯托克斯参数的压缩为3.6 dB，反压缩为9.4 dB。 显示英文摘要

摘要： We report the experimental demonstration of directly produced polarization squeezing at 1064 nm from a type I optical parametric amplifier (OPA) based on a periodically poled KTP crystal (PPKTP). The orthogonal polarization modes of the polarization squeezed state are both defined by the OPA cavity mode, and the birefringence induced by the PPKTP crystal is compensated for by a second, but inactive, PPKTP crystal. Stokes parameter squeezing of 3.6 dB and anti squeezing of 9.4 dB is observed.
