SOLID STATE BEAM CONTROLLED LIGHT MODULATOR.
Abstract
A study and investigation to prove the feasibili ty of an electron beam controlled solid-state light modulator are described. Studies were made with different systems. Among these were experiments exhibiting the Pockel's electro-opti-ffect and the reflex principle. Different types of tubes were used in these experiments; demountable and permanently sealed. Vacuum dep osition techniques were also studied. These experiments were performed with one or more of the following type crystals; ammonium dihydrogen phosphate (ADP), potassium dihydrogen phosphate (KDP), and potassium dideuterium phosphate (KD2P). The most promising of the above experi ments were the straight-through type tubes using KDP and ADP crystals. A major problem encoun tered was the high vapor pressure of the crystal material. Thus, it is recommended that the crys tal be mounted on the outside of the tube or inside the tube within a sealed volume, or inside the tube with a suitable means of gettering or continuous pumping.
