摘要:

The photobleaching of Rhodamine 6G (Rh:6G) in the polyacrylonitrile (PAN) matrix was studied at 5145 Å as a function of temperature. Photobleaching yield numbers were measured at room temperature and 106 °K. The quantum efficiency for fluorescence and the absorbtion cross sections were measured both for the solid polymer dye system and the liquid monomer dye solution. The observations were compared to Rh:6G in polymethylmethacrylate (PMMA). The PAN+Rh:6G system compares well to the PMMA+Rh:6G system and offers some advantages. Laser action was induced in a PAN+Rh:6G system in a longitudinally pumped polymer plate.

摘要:

Magnetic closure domains in ion‐implanted surface layers associated with magnetic bubbles in the underlying garnet films have been revealed by the Bitter pattern method using Ferrofluid. This is the first direct observation of the planar magnetization produced by ion implantation in garnets with negative magnetostriction. The closure domains are very sensitive to an in‐plane magnetic field and become too small to observe in rotating fields as large as those used in field‐access bubble devices. Closure domains around an ion‐implanted pattern in a garnet film and in a thin film of Permalloy evaporated onto a bubble garnet are also shown.
