Abstract
Abstract LASER OPTICAL CAVITY AND METHOD OF ALIGNMENT UTILIZING REFLECTORS MOUNTED ON SUBSTRATES HAVING A HEMISPHERICAL FORM AND SET INTO RIGID STRUCTURE FOR SUPPORTING THE SUBSTRATE AND PERMITTING IT TO BE ADJUSTED INTO ALIGNMENT TO FORM A PORTION OF AN OPTICAL CAVITY. A SEALANT HAVING A PLASTIC AND A RIGID STATE IS DISPOSED BETWEEN THE SUBSTRATE AND THE SUPPORT SO THAT BY EXCITING THE LASER AND SIMULTANEOUSLY SHIFTING THE SUBSTRATE WHILE THE SEALANT IS IN A PLASTIC STATE, AN INCIPIENT LASER BEAM CAN BE DEVELOPED AND MAXIMIZED, AFTER WHICH THE SEALANT IS CAUSED TO ASSUME ITS RIGID STATE AND MAINTAIN THE SUBSTRATE AND ASSOCIATED REFLECTOR IN THE ALIGNED POSITION.
