“…By fitting the experimental data with the above formula, the following characteristic values were obtained: τ 0 = 367 μs and N 0 = 8.47 E+20 ions/cm 3 . The results are in line with values reported in literature [17][18]. Graphical presentation of experimental data and curve fit are shown in Fig.…”

Abstract-Solar pumped laser (SPL) can find wide applications in space missions, especially for long lasting ones. In this paper a new technological approach for the realization of a SPL based on fiber laser technology is proposed. We present a preliminary study, focused on the active material performance evaluation, towards the realization of a Nd 3+ -doped fiber laser made of phosphate glass materials, emitting at 1.06 μm. For this research several Nd 3+ -doped phosphate glass samples were fabricated, with concentration of Nd 3+ up to 10 mol%. Physical and thermal properties of the glasses were measured and their spectroscopic properties are described. The effect of Nd 3+ doping concentration on emission spectra and lifetimes was investigated in order to study the concentration quenching effect on luminescence performance.

Highly Doped Phosphate Glass Fibers for Compact Lasers and Amplifiers: A Review

Abstract:In recent years, the exploitation of compact laser sources and amplifiers in fiber form has found extensive applications in industrial and scientific fields. The fiber format offers compactness, high beam quality through single-mode regime and excellent heat dissipation, thus leading to high laser reliability and long-term stability. The realization of devices based on this technology requires an active medium with high optical gain over a short length to increase efficiency while mitigating nonlinear optical effects. Multicomponent phosphate glasses meet these requirements thanks to the high solubility of rare-earth ions in their glass matrix, alongside with high emission cross-sections, chemical stability and high optical damage threshold. In this paper, we review recent advances in the field thanks to the combination of highly-doped phosphate glasses and innovative fiber drawing techniques. We also present the main performance achievements and outlook both in continuous wave (CW) and pulsed mode regimes.Keywords: fiber laser and amplifier; phosphate fiber; all-fiber master oscillator power amplifier (MOPA); rare-earth-doped fiber

“…Advanced glasses or possibly other materials will be necessary to handle the thermal load that will be present for reprated laser systems required for fusion energy power plants. Specifi cally the advanced glass APG -1, reported in 1996 by Schott Glass Technologies [37] , is the baseline material; however, other glasses such as APG -2 [38] are being considered for their improved mechanical properties and longer lifetime to reduce diode pump costs.…”
