Paper Abstract

The paper present the first stage of researches aiming to elaboration of Er3+ and Cr3+ ions doped ytterbium-phosphate laseroriented glasses pumped with flash lamp or with laser diode (?=97Onm) and emitting "eye-safe" radiation (?=1.54?m) and active fiber-oriented one for amplifiers on wave 1.53÷1.55?m. Worked out glasses are characterized by low coefficient of thermal expansion (high resistance on thermal shock), do not crystallize or show slight inclination to devitrification in temperatures of fiber forming and possess advantageous rheological characterization. Spectral and spectroscope investigations of glasses show on their usefulness for laser applications. Especially refers this to glasses with simultaneous content Er3+ and Cr3+ ions giving strong luminescence.
