Abstract: A high pressure, high power, continuous wave electro-dynamic laser having one of the electrodes (preferably the cathode) made of a porous conductive surface and a backing material capable of broad band acoustic absorption. Such an arrangement effectively absorbs acoustic disturbances which arises primarily from a linear instability within the resonant cavity of the electro-dynamic laser and thereby substantially reduces output flux modulations within the resonant cavity.

Abstract: A computerlike game which applies counting, memory and decisionmaking functions to privileged input signals independently and sequentially received from contesting players in emitting or not emitting an output signal. In its simplest form two pairs of ''''on-off'''' electrical switches are provided, with each pair secretly controlled by a contestant to generate ''''on'''' or ''''off'''' input signals. Circuit means count the total ''''on'''' signals received and store them in a memory means. A decisionmaking means generates an output signal when two ''''on'''' signals are received in the memory means. The output signal is used to indicate a winner of game or particular round.
