“…Work [4][5][6][7][8] shows that, the data of chemical composition of the gas filling the inner cavity of the cracks formed during the laser destruction of polymethylmethacrylate is shown by laser irradiation of PMMA in the nanosecond range and facilities, close to the conditions of our experiments. It turned out that the gas composition doesn't depend on the wavelength and intensity of the laser pulse.…”

The problem of studying the interaction of laser radiation with polymer materials lies in the study of the effect of intense energy fluxes on matter. The effect of pulsed laser radiation on a high-molecular substance was studied from changes in the electrical parameters of the irradiated materials. Changes in ε’, tg δ depending on the frequency of the external field, the dose of laser irradiation, temperature and time were investigated by a highly sensitive physicochemical method -the method of dielectric losses. This article examined the impact of laser radiation on the dielectric properties of polymethylmethacrylate at frequency of 50 kHz within the temperature interval from 170 to 420 K. The authors showed that the processing of the samples with laser radiation leads to substantial changes in the dielectric constant and tangent of dielectric loss angle.

“…1,11 Many attempts have been made to improve the laser-damage resistance of polymer materials, including adding plasticizers to improve macromolecular mobility and decreasing the concentration of local absorbing impurities to eliminate sources of laser energy absorption. 12,13 Recently, we have used polymer hydrogels instead of polymer solids as the host in guest-host systems for optical limiting applications.…”

Two types of chitosan hydrogel systems have been prepared that have a laser damage threshold (LDT) up to 35 times higher than commercial PMMA bulk materials. For these samples, the LDT increases with increasing water content. The mechanism of laser damage and the contribution of water to their high laser damage resistance have been examined. DSC measurements indicate water within the hydrogels exist in various states, each with different laser damage resistance properties. These various states play a key role in determining the LDT by controlling the dissipation of laser energy and providing a mechanism for self‐healing. This preliminary research shows that polymer hydrogels have potential for high power laser applications because they combine good mechanical integrity due to the polymer frame and good energy dissipation and healing characteristics due to the molecular mobility of water. These two traits allow for bulk shape‐retaining films with high laser damage thresholds and potential reversibility in damage processes. © 1999 John Wiley & Sons, Inc.
