“…Only a few compositions, which contained more than 20 mol% YF 3 were quenched rapidly between two brass plates. Glass formations in the binary 13 PbFrAIF 3 and ternary 9 PbFrAIFr YF 3 have been reported earlier using rapid quenching techniques and the results showed a very narrow range of glass formation. Therefore, the region obtained in the present studies, though very small, assumes importance because all the glasses have been quenched convenitionally and large pieces with 8-10 em thickness have been obtained.…”

Glass formation region, thermal stability and chemical durability have been determined in the four component glassy YF 3 -PbF 1 -CdF 1 -AIF 3 (YPCA) system. The notable features of these glasses are thermal stability at llOoC, IR transmission of -80% with long wavelength cut-off at 9.5 ~m and excellent chemical stability. These features are superior to zirconium fluoride glasses conventionally used as infrared materials. An important characteristic of the glass, i.e. water durability has been studied using three different techniques, namely static dissolution test, monitoring water absorption peak in the IR spectrum with dipping time and by analysis of the leached solution. The results from all the three methods complement each other and the glasses show excellent resistance to water attack at ambient temperature. YPCA glasses, therefore, appear as promising candidates for infrared related applications.

“…Waterproof fluoride glasses in an AlF 3 system have been proposed by Iqbal et al [17] and Wang et al [18] Iqbal et al reported that an AlF 3 fluoride glass system is 500 times as water resistant as ZBLAN glass. [17] Recently, our group has successfully drawn a waterproof Pr 3+ -doped optical fiber and also demonstrated multi-color laser oscillation pumped by a 442.6-nm GaN laser diode.…”

We successfully drew a low-loss Dy-doped optical fiber (0.3dB/m at 532nm) of a waterproof fluoro-aluminate glass system and demonstrated yellow laser oscillation in the Dy 3+ -doped fluoride fiber pumped by a 398.8-nm GaN laser diode. The maximum output power was 10.3 mW and the slope efficiency was 17.1% at 575 nm. Since the fluoroaluminate-glass system has a remarkable water resistance advantage compared to ZBLAN glass, Dy-doped fluoroaluminate glass fiber is expected to contribute to making a solid-state yellow fiber laser with high chemical durability without a frequency doubling technique.
