  We present the spectroscopic characterization and the laser measurements obtained with a 10 at.% Yb:Y3Sc1.5Al3.5O12 (=YSAG) ceramic sample. Longitudinally pumped in quasi-Continuous Wave (QCW) and in Continuous Wave (CW) at 936 nm, the ceramic has shown good laser performance. In the former pumping regime ...  Read More

9. Impact of carbon black aggregates on the optical properties of black rubber samples in the terahertz frequency range

Shinichi Watanabe; Misako Fujii; Makoto Okano

Volume 10, Issue 1 , January 2019, Pages 49-52

  We report on the optical responses of black rubber samples in the terahertz regime as a function of the carbon black (CB) concentration. We prepared samples with different CB concentrations and investigated their absorbance, birefringence, and the angle of the slow optic axis in the terahertz frequency ...  Read More
