Experimental evidence of the validity of the McCumber theory

Webacteristics in the framework of the Stewart-McCumber theory [13, 14]. The Stewart-McCumber model describes the semi-classical regime of a small Josephson junction for … WebThe spectroscopic data are analyzed using a generalized McCumber theory. The peak stimulated emission cross section is 0.54 x 10/sup -20/ cm/sup 2/. This, together with preliminary single-pass measurements, indicate that gain for mullite is about 2.6 times smaller than gain for alexandrite. エアダクトホースとは

Reciprocity between emission and absorption for rare earth ions in …

Web28 apr. 2006 · The theory was tested by comparing the cross sections calculated using the McCumber relation with those obtained from measurements. At room temperature, a number of ground state transitions of three different rare earth ions (Nd, Er and Tm) in oxide and fluoride glass hosts have been studied. WebThe absorption and emission cross sections and the passive losses of the fiber were obtained from a fitting procedure of theoretical to experimental values. The method was checked by means of a home-made photonic crystal fiber to verify its reliability.
