Lasers are becoming more and more common and can damage eyes and sensors, so arise the need for efficient protection. A possibility is the use of filters with optical limiting abilities. Optical limiting leads to a reduced transmittance of these filters above a certain light energy. Solid-state optical limiting filters consist frequently of poly(methyl methacrylate) (PMMA). Using dyes is an often used way to provide optical limiting qualities to polymers. PMMA does not offer the possibility to attach the dye covalently to the polymer chain. Poly(lactide), also a transparent polymer, has so far not been used for filters for optical limiting. Its polymerization mechanism offers a simple possibility to a covalent binding of the dyes, by using them as initiator. This should be, like the attaching of big side groups to dyes, a possibility to increase stability of dyes against aggregation. Hybrids out of polymers and dyes and filters thereof could be produced. The polymers were analyzed by nuclear magnetic resonance, gel permeation chromatography, and nonlinear optical measurements. Including azophloxine leads to an attenuation of the laser beam in the range of 10 −3 and Eosin B even to 10 −5 . The eosin sample shows a two magnitudes better attenuation then usual guest-host systems like poly(methyl acrylate) with carbon nanotubes.

Detonation nanodiamonds exhibit strong nonlinear optical properties depending on their electronic properties. In the present paper, the nanodiamond functional groups are chemically modified to obtain nanodiamonds with primary amines on their surface. The optical properties of such nanodiamonds placed in water suspensions are studied and compared with the one of classical detonation nanodiamonds. Transmission, scattering and Z-scan experiments are performed for two different wavelengths (532 nm and 1064 nm). A lower threshold for optical limiting associated to more pronounce non-linear optical effects is detected at the wavelength of 1064 nm compared to the one at 532 nm. This effect may be due to a stronger nonlinear backscattering behavior at 1064 nm. Moreover, a striking result obtained from the Z-scan experiments reveals a completely different behavior of the functionalized nanodiamonds for both wavelengths. This result is discussed in regard to the electronic properties of the material and possible charge transfer.

Two-photon absorption studies in organic compounds and polymers

High two-photon absorption (2PA) cross-section materials have been frequently studied during the latest years due to the wide variety of technological applications, such as two-photon absorption microscopy (2PM) and microfabrication. The characterization of new materials with high nonlinearities is, therefore, indispensable to develop new applications and improve previously existing ones. Here, three different groups of novel organic compounds had their nonlinearities characterized through two-photon absorption measurements: fluorenone based compounds, which are usually used in two-photon absorption microscopy; BF2-naphthyridine (BODIPY) complexes, which have a wide range of applications, from solar cells to photodynamic therapy; and binaphthalene-based polymers, with structures built to generate large nonlinearities through inherent chirality. All compounds had their twophoton absorption spectra studied through absorptive Z-Scan, with density functional theory (DFT) calculations made to interpret the results for the first two groups of compounds, and polarization controlled measurements made for the polymers. The highest 2PA cross-section presented by the fluorenone-based compounds was of 224 GM at 710 nm, large and within the wavelength range for 2PM applications; for the BODIPYs, the largest observed cross-section was of 268 GM at 990 nm, of the same order of magnitude of more complex compounds; and 680 GM at 1100 nm for the polymer, showing a high cross-section as expected from its structure. The desired applications for the studied molecules were shown valid, and their characterization gave a better understanding of how to increase their nonlinearities depending on the compound manufacture.
