A CO2 waveguide laser in a monolithic RF excited structure has been built at S.A.T. Besides its ruggedness and simplified design this new structure warrants : - A longer lifetime for the sealed off laser without electrodes in the plasma. The laser head is fed through a light, coaxial cable and looks like a big pencil (length = 200 mm, diameter = 25 mm, weight = 200g) This uncooled low power version emits 1 to 4 W in a 30 s run. Two civilian applications have been investigated : - Medical aalicatiOn : The odontological CO, laser (in collaboration with PR J. MELCER from Paris V University). This light laser head is especially suitable for the dental surgeon working with the laser in hand : - On the decayed areas the laser beam sterilizes and hardens the dentinary surface. - On the mucous membrane the laser beam burns outgrowths. - Industrial a22lication : Splicing of optical fibers (in collaboration with the CABLOPTIC company). Due to the high absorption of silica around 10 μm, CO2 laser light turns to be a very promising, non-contact fusing agent for optical fibers : CO2 laser splicing technique allows improved control of localization as well as concentrati6n of energy on the area to be fused. This method limits the ionic (OH-) pollution thus improwing mechanical resistance.
