“…It was shown previously [5] that in the lasing spectrum of a laser based on borosilicophosphate (BSP) glass coactivated by Er 3+ and Yb 3+ , we observe two groups of narrow lines within the IR luminescence band, corresponding to the optical transitions 4 I 13%2 → 4 I 15%2 in the Er 3+ ions. The number of lines, their spectral position, and also the time dependence of the intensity of the laser emission depend on the pump power.…”

“…The electronic level diagram, with an indication of radiative and nonradiative transitions, is shown in Fig. 1 consists of two groups of inhomogeneously broadened sublevels [5], to which correspond the maxima A (λ , 1541.6 nm) and B (λ , 1534.9 nm) of the luminescence band (Fig. 2a).…”

“…The wavenumbers of the individual lines in the sets, which appear for excitation conditions P ≤ 100 W and P = 200 W, are presented in Table 1. As shown in [5], the lasing lines for Er,Yb:BSP glass correspond to transitions from lower components of the Stark splitting of the level Table 1, are shown in Fig. 3 for the cases P ≤ 100 W and P = 200 W. We took the values of the energies for the shortest wavelength lines as the zero reference points for the energy levels of the Stark components for each center.…”

The influence of the cavity trapped amplified luminescence (CTAL) on the threshold, power and dynamic characteristics of Er, Yb : glass lasers with end and side diode pump configurations has been studied. The CTAL loss coefficient has been evaluated using the luminescence balance equation. The inverse proportion dependence of the CTAL loss coefficient on the cavity length has been revealed. It has been shown that amplification of luminescence in the laser cavity leads to a significant increase of the threshold pump power (∼3-5 times). The Er, Yb : glass laser generation dynamics has been modelled taking into account the luminescence evolution beginning with the onset of the diode pumping pulse. Depending on the diode pumping pulse amplitude, the increase or decrease of the Er, Yb : glass laser pulse generation delay can be observed.

Erbium‐incorporated silicophosphate glasses are very desirable in principal sectors such as photonics, optoelectronics, lasers, and illuminating diodes. The focus of the current investigation has been on determining how the erbium dopant affects the optical, physical, and structural characteristics of the silicophosphate‐based glasses. The pure silicophosphate glasses and doped with various contents of erbium were prepared by the sol–gel process in this work. The noncrystalline character of the glasses synthesized was confirmed by the XRD patterns that were obtained. The optical measurement showed that the addition of trivalent erbium ions resulted in an increase in the refractive index of the samples and a decrease in their energy band gap values. It demonstrated the presence of P–O–P linkage stretching vibration modes that were both symmetrical and asymmetrical, P–O in PO4 bending vibration modes, OH group elongating and flexure vibrations, and P–O–H water absorption in glasses. The theoretical values of the optical basicity (Ʌth) increased from 0.465 to 0.472, while the values of the interaction parameter (A) decreased from 0.218 to 0.214 . Silicophosphate glasses doped with trivalent erbium ions show promise as optoelectronic and optical filter system materials.
