A number of different designs of CO2 wavegulue lasers have been built in order to establish the perforkiance of rugged, reliable devices ah.i.d to test their suitability for a number of different applications. In particular the need to demonstrate long active and passive life times has led to the adoption ot fluxless, controlled atmosphere brazing and welding processes during a number of the construction phases. Fully developed lasers have been built which have demonstrated 5000 hours active life and 7 years shelf life to date. The further need for more compact, lower cost and higher power lasers has resulted in the development of new ceramic bonding techniques- Prototype lasers have been built to establish the design parameters and technology for folded waveguide paths leading to increased power from compact, smaller dimensioned devices-In this paper the technology advances which have now made the waveguide laser a viable tool for military, medical and industrial applicatioo.s will be described and discussed.
