Excellent Two-Photon Absorption and Optical Limiting Performance of [Material Name]

From Table 2, it can be seen that the two-photon absorption of the material is comparable to that of carbon dioxide and oxygen. Although the two-photon coefficient is numerically smaller than that of femtosecond and picosecond pulse bulk gallium nitride, the larger modulation depth results in a maximum transmittance of 23% and a minimum transmittance of 75% in this experiment. Considering the low material concentration of the dispersion liquid, this indicates excellent optical limiting performance. This material shows promise for applications in high-power laser systems due to its strong optical limiting capabilities.
