Optical limiting behavior of bismuth oxide-based glass in the visible range
The authors report experimental results on the optical limiting behavior of a bismuth oxide-based glass by exciting the samples with nanosecond laser pulses at 532 and 598 nm . The results show that two-photon and free-carrier absorption processes contribute for the nonlinear absorption. Values for...

| Zusammenfassung: | The authors report experimental results on the optical limiting behavior of a bismuth oxide-based glass by exciting the samples with nanosecond laser pulses at 532 and
598
nm
. The results show that two-photon and free-carrier absorption processes contribute for the nonlinear absorption. Values for
β
, the two-photon absorption coefficient, and
σ
e
, the absorption cross section due to free carriers, were determined. The values of
β
and
σ
e
are dependent on the amount of bismuth oxide in the glass composition. |
