Broadly tunable Cr:ZnSe laser

In our study we have investigated Cr:ZnSe bulk crystal samples grown by the special Bridgeman method. The Cr
²⁺
ion concentration was 1x10
¹⁹
cm
^-3
. Cr:ZnSe crystal bulks with a diameter up to 50 mm and a length up to 100 mm were produced. From the bulk the Cr:ZnSe dispersive prism was polished. This Cr:ZnSe dispersive prism was utilized as a laser active material and simultaneously as a wavelength tuning element inside the laser resonator.
