ABSTRACT:
A laser nozzle and optical cavity wall construction is formed of a plurality of stacked blocks bonded together to prevent inter-nozzle leakage and optical cavity sidewall mismatch in the flow area significant thereto. The blocks are formed having end sections which are bonded together with contoured center sections forming the plurality of nozzles and with integral elongated projections extending downstream to form the optical cavity walls. The blocks have hollow ends which absorb thermal expansion in bending rather than in crushing and tension. The laser device flanges holding the ends of the blocks are also provided with a cantilevered spacing block which maintains a seal load while allowing for expansion, preventing undue stresses resulting from temperature changes.
