Abstract: A compact excimer laser, including a housing structure having a plurality of walls forming an internal laser cavity. A gas is located within the laser cavity and with the gas capable of lasing action. A pair of spaced electrodes are located within the laser cavity and form an electrical discharge area between the electrodes for stimulating gas within the discharge area to lasing action in accordance with an electrical discharge between the electrodes. One of the pair of electrodes is located along a central position within the cavity and is grounded to the housing structure. The other of the pair of electrodes is located adjacent to but spaced from one of the walls of the housing structure and with the other electrode mounted on a main insulator member.

Abstract: A multi-stable optical device and system which utilizes an active optical element such as a spatial light modulator (SLM) in a feedback path configuration. The elementary system consists of a pair of image element (pixels) on the SLM whose input and outputs are coupled to each other by purely optical means. In another arrangement, multi-stable performance is achieved by optical path geometry defining a single pixel which performs in conjunction with a feedback path. Analysis is provided identifying the equilibrium states of the system as well as those equilibrium states which are stable in nature.
