13 March 2008Iron doped CdxMn1-xTe crystals: new gain media for mid-IR room temperature lasers
The objective of this study is to determine feasibility of ternary Fe:CdMnTe crystals for room temperature lasing in the
mid-infrared spectral range. Fe:CdMnTe samples were grown with a modified Bridgman technique. At room temperature, Fe:CdMnTe features wide (2800-6000nm) absorption and emission (3700-6500nm) bands. The kinetics of the photoluminescence were measured over 14K-300K temperature range under 2920nm and 532nm excitation. The low temperature (14K) kinetic of luminescence under 2920nm excitation was a single exponential with a decay time of 75μs. The room temperature emission cross-section was estimated to be 2x10-18cm2.
