First step of Er-Yb laser based on PTR glass creation was made. Complex study of luminescent characteristics of PTR glass doped with Er-Yb with recorded holograms was made. Direct measurements of population inversion of main Erbium level 4I13/2 for different Erbium concentrations and pumping power was made. Was shown that spectral and luminescent characteristics of poly-functional PTR glass doped with Er-Yb and recorded holograms are comparable to the traditional laser barium phosphate glass.
Two types of lead-fluoride nano-glassceramics doped with rare-earth ions (Tm, Ho, Pr, Er, Yb) have been developed and
synthesized. The size of crystalline phase achieved up to 40 nm. Spectral and luminescence properties of nanoglassceramics
have been investigated. It was shown, that emitting probabilities of different transitions changed during
thermal treatment. The entry of rare-earth ions in crystalline phase resulted in a broadening of emission spectra. For
example, the bandwidth of emission spectrum at 1.55 mkm achieves 70 nm for Er-doped nano-glassceramics. RE-doped
nano-glassceramics are promising candidates for different photonics applications, sensors, fiber and waveguide lasers.
Gain/loss spectra in ytterbium-erbium doped bulk glass samples have been investigated within spectral range of 1.5 μm. Experimental methods for determination of the population of excited metastable level, gain/loss spectra, and their variations versus pump power have been developed. A comparison of the experimental and calculated gain/loss spectra has been done.
