zinc germanium phosphide (zngep2; zgp) appears to be the most important representative of this group but the chalcogenide aggase2 will also be investigated. in addition ktiopo4 (ktp) will receive attention because its use as optical parametric oscillator up to 4 µm ir generation also is principally limited by birefringent walk-off and for
germanium is a chemical element with the symbol ge and atomic number 32. it is a lustrous hard-brittle grayish-white metalloid in the carbon group chemically similar to its group neighbours silicon and tin.pure germanium is a semiconductor with an appearance similar to elemental silicon. like silicon germanium naturally reacts and forms complexes with oxygen in nature.
