Abstract

A light deflection device having a deflection capacity of the order of 10/13/ spots/second is shown in the drawing. A tunable dye laser 10 using R6G dye can be tuned over a range of at least Delta Lambda = 700 Angstroms. The light is then passed through a beam expander 12 to a spectroscopic grating 14, such as reflective echelles having a resolving power, Lambda /Delta Lambda, in excess of 10/6/. The light is then passed through a focusing lens 16 to the screen 18. Tuning the dye laser over a range of Delta Lambda = 150 Angstroms in a few nanoseconds, the laser light can be deflected with spatial resolution N = (150/2.3x10/3/) = 65,000 spots in a few nanoseconds, thereby providing a deflection rate of 10/+13/ spots/second.
