We report on a direct measurement method for acquiring highly precise reflectance spectra of gain elements for semiconductor disk lasers under optical pumping. The gain element acts as an active mirror, and the active mirror reflectance (AMR) was measured with a weak and tunable probe beam coincident on the gain element with a high-power pump beam. In particular, we measured the spectral AMR of...
rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
We investigate the spin Seebeck effect and pumping in a junction between ferromagnetic insulator magnetic impurity deposited on normal metal. By numerical renormalization group calculation, we show that current is enhanced by Kondo effect. This suppressed increase of temperature or field which comparable with temperature. Our results indicate transport can be direct probe excitation strongly co...
