Glass–ceramic composites based on the YAB and GdAB micro-crystals have been prepared by quenching YAB–B2O3 and GdAB–B2O3 melts and characterized by X-ray diffraction and spectroscopic methods. The vitrified melt was shown to contain micro- and nano-crystalline rare-earth borate phases. Their distribution over the composites has been investigated by electron microscopy and three-dimensional X-ray tomography.

    The search for new crystalline host materials for the usage in lasers emitting in the eye-safe spectral range of 1.5–1.6 Β΅m is an important task. The aim of this work was to study the growth technique, spectroscopic properties and laser characteristics of new active media – crystals Er3+,Yb3+:Ca2RE2(BO3)4 (RE=Y, Gd).Calcium-yttrium Er3+,Yb3+:Ca3Y2 (BO3)4 (CYB) and calcium-gadolinium Er3+,Yb3+: Ca2 Gd 2(BO3)4 Β (CGB) oxoborate crystals co-doped with erbium and ytterbium ions were investigated. Polarized absorption and emission cross-section spectra were determined. The lifetimes of 4I11/2 and 4I13/2 energy levels of Er3+ ions were measured and ytterbium-erbium energy transfer efficiencies were estimated. The calculation of the gain cross-section spectra was performed. By using of Er3+,Yb3+: Ca2 RE 2(BO3)4Β  (RE=Y, Gd) crystals the laser performance was realized, for the first time to the best of our knowledge. The laser characteristics were studied in a quasi-CW (QCW) laser operation.The wide band with a peak at the wavelength of 976 nm is observed in the absorption spectra of both crystals. This peak coincides with the emission wavelength of the pump laser diodes for Yb-doped active media. The maximum value of absorption cross-section was 1.7 Γ— 10–20 cm2 for polarization E // b for both crystals. The lifetimes of the upper laser level 4I13/2 of Er3+ ions were 580 Β± 30 ΞΌs and 550 Β± 30 ΞΌs for Er,Yb:CYB and Er,Yb:CGB crystals, respectively. The energy transfer efficiencies from ytterbium to erbium ions for an Er,Yb:CYB and Er,Yb:CGB crystals were 94 % and 96 %, respectively. According to gain spectrum of the Er,Yb:CYB crystal the gain band peak is centered at the wavelength of 1530 nm. The maximum QCW output power was 0.5 W with slope efficiency of 13 % regarding to absorbed pump power for an Er,Yb: CYB crystal. The laser beam parameter M2 did not exceed &lt; 1.5.Based on the obtained results, it can be concluded that these crystals are promising active media for lasers emitting in the spectral range of 1.5–1.6 ΞΌm for the usage in laser rangefinder and laser-induced breakdown spectroscopy systems, and LIDARs.Поиск Π½ΠΎΠ²Ρ‹Ρ… кристалличСских ΠΌΠ°Ρ‚Ρ€ΠΈΡ† для примСнСния Π² Π»Π°Π·Π΅Ρ€Π°Ρ…, ΠΈΠ·Π»ΡƒΡ‡Π°ΡŽΡ‰ΠΈΡ… Π² условно бСзопасном для Π³Π»Π°Π· ΡΠΏΠ΅ΠΊΡ‚Ρ€Π°Π»ΡŒΠ½ΠΎΠΌ Π΄ΠΈΠ°ΠΏΠ°Π·ΠΎΠ½Π΅ 1,5–1,6 ΠΌΠΊΠΌ, являСтся Π°ΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΠΉ Π·Π°Π΄Π°Ρ‡Π΅ΠΉ.

    Solid-state lasers emitting in the 1.5–1.6 ΞΌm spectral range are very promising for eye-safe laser range finding, ophthalmology, fiber-optic communication systems, and optical location. The aim of this work is the investigation of spectrosposcopic and laser properties of gain medium based on borate crystal for abovementioned lasers.Spectroscopic and laser properties of Er,Yb:YAl3(BO3)4 crystals with different concentrations of dopants were investigated. Polarized absorption and emission cross-section spectra were determined. The ytterbium- erbium energy transfer efficiency was estimated. The maximal energy transfer efficiency up to 97 % was obtained for Er(4 at.%),Yb(11 at.%):YAl3(BO3)4 crystal.The laser operation of heavily doped crystals with erbium concentration up to 4 Π°t.% (2.2^1020 cm^3) was realized. By using of Er(2 at.%),Yb(11 at.%):YAl3(BO3)4 crystal a maximal continuous- wave (CW) output power of 1.6 W was obtained at 1522 nm with slope efficiency of 32 %. By using of Er(4 at.%),Yb(11 at.%):YAl3(BO3)4 crystal a maximal peak output power up to 2.2 W with slope efficiency of 40 % was realized in quasi-continuous-wave regime of operation. The spatial profile of the output beam was close to TEM00 mode with M2 &lt; 1.2 during all laser experiments.Based on the obtained results, it can be concluded that Er,Yb:YAl3(BO3)4 crystals are promising active media for lasers emitting in the spectral range of 1.5-1.6 pm for the usage in laser rangefinder and laser- induced breakdown spectroscopy systems, and LIDARs.Π’Π²Π΅Ρ€Π΄ΠΎΡ‚Π΅Π»ΡŒΠ½Ρ‹Π΅ Π»Π°Π·Π΅Ρ€Ρ‹, ΠΈΠ·Π»ΡƒΡ‡Π°ΡŽΡ‰ΠΈΠ΅ Π² ΡΠΏΠ΅ΠΊΡ‚Ρ€Π°Π»ΡŒΠ½ΠΎΠΉ области 1.5β€’1.6 ΠΌΠΊΠΌ, находят ΡˆΠΈΡ€ΠΎΠΊΠΎΠ΅ ΠΏΡ€ΠΈΠΌΠ΅Π½Π΅Π½ΠΈΠ΅ Π² Π΄Π°Π»ΡŒΠ½ΠΎΠΌΠ΅Ρ‚Ρ€ΠΈΠΈ, ΠΎΡ„Ρ‚Π°Π»ΡŒΠΌΠΎΡ‚ΠΎΠ»ΠΎΠ³ΠΈΠΈ, Π²ΠΎΠ»ΠΎΠΊΠΎΠ½Π½ΠΎ-оптичСских систСмах ΠΈ оптичСской Π»ΠΎΠΊΠ°Ρ†ΠΈΠΈ.
