ROMOPTO '97: Fifth Conference on Optics.
`Special mirror' concept is presented as a `spare module' for a GaAs extracting mirror technological processed with GaAs thin films, mounted within two kinds of c.w. CO2 laser resonators: U-type resonator (with optical pathlength Lr equals 4 m) and U

ROMOPTO '97: Fifth Conference on Optics.
This paper reports on the optical properties of polycrystalline p-type InxGa1-xSb (x equals 0.20) over the wavelength range 15 - 30 micrometers , at room temperature. The material was obtained by direct synthesis from the elements and rapidly crystal

Polycrystalline p-type InxGa1-xSb (x=50.20) for optoelectronic devices has been obtained by rapid direct synthesis from highpurity (99.9999%) In, Ga, and Sb. The uniformity of the composition has been checked by neutron activation analysis and also b
