Room- and low-temperature transmission of diffusion-doped Fe2+ : ZnSe polycrystal at 2940 nm

Room- and low-temperature transmission of diffusion-doped Fe2+ : ZnSe polycrystal at 2940 nm

Transmission of a polycrystalline Fe2+ : ZnSe sample during irradiation by a pulsed Er3+ : YAG laser with a wavelength of 2940 nm is measured at low and room temperatures. It is found that the sample in a strong field (energy density 1.3 J cm-2, laser pulse duration 320 ns, peak intensity 4.1 MW cm-...

Zusammenfassung:Transmission of a polycrystalline Fe2+ : ZnSe sample during irradiation by a pulsed Er3+ : YAG laser with a wavelength of 2940 nm is measured at low and room temperatures. It is found that the sample in a strong field (energy density 1.3 J cm-2, laser pulse duration 320 ns, peak intensity 4.1 MW cm-2) is bleached almost completely at both low and room temperatures. The temperature dependence of transmission is measured in the range of 105 - 273 K in weak and strong fields.
