Abstract

Rare-earth (R) phosphate glasses (R2O3)x.(P2O5)1-x where x=1/4 or 1/6 have shown great promise in the laser and optoelectronics industry. This is because the rare-earth ions possess the required energy levels for achieving successful population inversion and the non-linear refractive index is large enough to exhibit the desired optical effects without causing beam breakup and damage. Moreover, the particularly high concentrations of rare-earth ions present in these materials results in a myriad of exotic physical properties at low temperatures: negative thermal expansion, negative pressure dependence of bulk moduli and unprecedented magnetic, magneto-optical and opto-acoustic phenomena.
