Comparison of the ablation behavior of polymer films in the IR and UV with nanosecond and picosecond pulses

Article Abstract:

A study was conducted to analyze the ablation behavior in the infrared and ultraviolet spectra areas of the doped standard polymer, PMMA, and a customized photopolymer. Samples of the copolyesters were irradiated with 266 nm at 266 nm. Experimental results indicated that the presence of an absorbing chromophore in the polymer is a requirement for realizing high-resolution structuring.

Novel laser ablation resists for excimer laser ablation lithography. Influence of photochemical properties on ablation

Article Abstract:

The ablation characteristics of various polymers were studied at low and high fluences. The amount of detected gaseous products follows the same trend as the ablation activity suggesting a combined mechanism of photochemical decomposition and associated volume increase of the designed polymers.

Isosteric heat of argon adsorbed on single-walled carbon nanotubes prepared by laser ablation

Article Abstract:

Twenty-one adsorption isotherms for argon on single-walled carbon nanotubes are produced by laser ablation. The coverage dependence of the isosteric heat of adsorption for argon on single carbon nanotubes (SWNT) prepared by laser ablation is determined.
