Abstract
A method of forming a hard vacuum seal for use in a gas laser but not limited thereto. The method comprising the steps of polishing the surfaces to be joined together and then cleaning the surfaces with a plasma cleaner. Next, a force is applied to hold the surfaces in contact and then molten indium is applied onto the adjoining surface and allowed to cool in order to set the seal. In the method of forming the gas laser seal for fine alignment of the mirror surfaces, the seal is reheated, the mirrors realigned by sliding across the laser cavity while the laser is operative and the laser output is measured for maximum laser output. Then the seal is allowed to reset.
