EXTREMELY FAST GASEOUS STARK FIELD LIGHT MODULATORS AND Q-SWITCHED LASER FOR THE INFRARED WAVELENGTH REGION

摘要

An infrared light intensity modulator utilizing the electro-optical Stark effect at high modulating frequencies in molecular gases having non-linear molecules with permanent dipole moments. Modulating frequencies greater than 0.5 MHz are obtainable for the first time. A D.C. bias field superimposed on the modulating field enhances the Stark effect and changes the frequency of the modulated output. Also, a cell utilizing this Stark effect is used as an active electrooptical element in a laser cavity to form a novel Q-switched laser to produce high energy laser pulses of short duration.
