Real-Time Dry Silver Film Development Using CO2 Laser Irradiation
Abstract
This report presents the preliminary results of a feasibility demonstration of real-time (less than 1 sec) development of 3M 7969 dry silver film utilizing a CO2 laser under nonscanning, static area conditions. The standard thermal development procedure for this film requires 15 seconds of exposure at 250 F. It was surmised that the use of a CO2 laser beam as a heat source would result in a substantial reduction in the development time. Initial estimates indicate that a 10-100 watt diffraction limited cw laser beam operating at 10.6 microns will do the job. Linear extrapolation of experimental results indicates that a single mode (TEM00), single line P (20), CO2 laser of approximately 16 watts average power will satisfy the real-time development requirement for line scan recorders with a writing rate of 0.25 MHz on film with a resolution of 2000 lines per inch.
