High Density Optical Memory.
Abstract
The purpose of this research is to study the problems associated with an experimental read-write, random access optical memory and to demonstrate its feasibility. The memory element employed is the (M sub A) color center in KCl:NaCl. The fact that it is extremely well studied and that the writing wavelength is in the visible range determined its choice for this study. Topics discussed in the report include the following: Color center physics; Diffraction limited focusing and heating effects; Crystal preparation; Thermo electric cooling; Polarization control; Deflection systems; Memory controller; Computer interface; Experimental results.
