Beschreibung
Zusammenfassung:	A semiconductor member of a laser screen cathode-ray tube is made of a semiconductor compound selected from the group consisting of binary, three-component and four-component compounds of elements of the second and sixth Groups of the Periodic System and a support member is made of a semiconductor compound of the same type with a bandgap width such as to make it transparent for radiation generated by said screen. Maximum of 15% of atoms of the overgrown support member are substituted for isovalent atoms and the bandgap width of the support member is at least 0.1 eV greater than the bandgap width of the semiconductor member. The support member is overgrown from vapor phase on a partly transparent mirror deposited to one side of the semiconductor member forming an optical cavity with a reflecting mirror deposited to the opposite side of the semiconductor member.
