摘要
Coherent amplification of images illuminated by the 632.8-nm radiation of He-Ne has been successfully demonstrated using a two-stage injection-locked pulsed dye amplifier technique. A gain of three times has been measured using Cresyl Violet 620 and Rhodamine B in ethanol, while maintaining signal bandwidth, relative phase, and direction, over a one-quarter μs pulse duration. A space bandwidth product of 500 000 was obtained by incorporation of the image amplifier into an optical image processing system.
