Abstract
A method of forming a hermetically sealed electrodless lamp envelope includes: (1) forming an envelope blank; (2) depositing a gas and light generating expedient material in an interior of the envelope blank; (3) arranging a window on an open end of the envelope blank; and (4) using an ultra-short pulse laser system to locally heat the axial end of the envelope blank and the window to seal the window on the envelope blank without degrading the contents deposited in an interior of the envelope or damaging or cracking the envelope blank and/or window.
