A laser system is described comprising: (a) a laser having a tube and mirror laser beam generating system mounted on base structure and at each of anode and cathode ends of the tube and mirror system a wobble plate surrounding the beam path and supporting a transmission mirror forming a part of the system. The wobble plate is mounted so as to track thermal drift of the system's optical alignment; (b) an optical delivery assembly, comprising: (i) a first mounting block providing a cavity adjacent and removably secured to a selected the wobble plate for corresponding thermal tracking thereof and having an opening extending therethrough for passing the laser beam; (ii) focusing means mounted on the first mounting block including a focusing lens mounted within the cavity for focusing the laser beam with means separately supporting the focusing lens and accessible externally of the cavity for precisely adjusting the focusing lens with respect to the beam; (iii) beam splitting means mounted on the first mounting block and located in the path of the laser beam for providing a split off beam directed away from the path of the laser beam; (iv) first circuitry means mounted on the first mounting block for detecting the split off beam and developing an electrical signal responsive to the level thereof; and (v) a scattering shutter slidably mounted on the first mounting block and having a first normal position with filtering means positioned for scattering the laser beam and a second withdrawn position with an aperture positioned for passing the laser beam.
