Abstract:
An evacuated envelope having at least one ceramic component and one aluminum component sealed to one another along a common interface. A metallized layer is on said ceramic component along said interface and a fused solder having an Al-Si eutectic structure with 89% aluminum and 11% silicon is along said interface.
Abstract:
Cold cathode gas lasers where the cathode of the circuit exciting the discharge, is an aluminium tube which forms an integral part of the sealed envelope of the laser.Such a structure can be used in lasers whether coaxial or otherwise. It makes it possible to improve their performance characteristics and to reduce their cost.
