摘要：

The maximum optical-absorption cross section of Cr2+ ions was evaluated from near-infrared (NIR) absorption spectroscopy and direct measurements of the chromium concentration in Cr2+ :CdSe crystals. The emission lifetime of the excited state, E-5, of Cr2+ was measured as a function of Cr2+ concentration in the 2 x 10(17)-2 x 10(18) ions/cm(3) range and as a function of temperature from 77-300 K. Lifetime values were as high as similar to6 mus in the 77-250 K range and decreased to similar to4 mus at 300 K because of nonradiative decays. Assuming that most of the Cr dopant is in the Cr2+ state, an optical-absorption cross section sigma(a) of (1.94 +/- 0.56) x 10(-18) cm(2) was calculated. Implications for laser performance are discussed.
