Abstract
Degenerate two-photon absorption (TPA) in a binary glass with composition TeO.sub.2-PbO is reported. The TPA coefficient, [alpha].sub.2, obtained with nanosecond laser pulses at 532 and 590 nm, increases when the relative amount of PbO is increased. The maximum TPA coefficient, [alpha].sub.2=12.6 cm/GW, is comparable to or larger than the values reported for crystalline semiconductors and other recently reported glasses.
