Optical limiting threshold

WebThe suitability of these films as optical limiting material was identified. The magnitude of third-order nonlinear susceptibility χ (3) was also estimated to be in the range of 10 −3-10 −2 esu and the least optical limiting threshold was shown by Sn 0.93 Sm 0.07 O 2 films. WebApr 14, 2024 · The incorporation of 20% Al content in the DBRs opens an optical pumping window from 700 to 820 nm, where the excitation laser light can effectively reach the GaAs cavity above its bandgap while remaining transparent to the DBRs. This results in a substantially improved pump efficiency, a low lasing threshold, and a high thermal stability.
