Interaction of pulsed carbon dioxide-laser radiation with non-metals

Interaction of pulsed carbon dioxide-laser radiation with non-metals. Brighton, D. R.; Gibbs, W. E. K. (Mater. Res. Lab., Maribyrnong, Aust.). U. S. NTIS, AD Rep., AD-A034410, 37 pp. Avail. NTIS From: Gov. Rep. Announce. Index (U. S.) 1977, 77(7), 140 (English) 1976. CODEN: XADRCH. DOCUMENT TYPE: Report CA Section: 57 (Ceramics) Samples of crown glass, fused SiO2, Perspex [9011-14-7], and Irtran 1 [7783-40-6] were irradiated with 0.2-ms duration pulses from a CO2 laser, at energy ds. 10-800 kJ/m2. The damage induced was thermal in origin and was controlled more by the absorption depth in the material than by thermal diffusion. The major damage mechanisms were cracking and flaking, in the case of crown glass, and vaporization in the cases of fused SiO2 and Perspex. Irtran 1 was the most difficult to damage because of its comparatively large absorption depth. Impulse prodn. was studied and was explained by simple models involving vaporization and the excitation of laser-supported waves.

DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) Section cross-reference(s): 76 A liq. crystal display (LCD) with reduced glare includes pixel control electrodes constructed as a transparent metal stack having a photonic band gap (PBG) structure that transmits a visible range of wavelengths and suppresses a non-visible range of wavelengths. A liq. crystal layer between the pixel control electrodes controls the transmission of light in response to a voltage applied across the pixel control electrodes. A light emitting structure (LES), such as a light emitting diode (LED) or light emitting polymer (LEP) device includes a cathode electrode, a substrate, an active layer for emitting visible light, and a transparent anode electrode having a PBG structure. The above devices have reduced undesired glare, reduced power consumption and increased responsivity.
