In certain embodiments, one or more of the optical elements 220 within the laser head 200 (e.g., lens 212, lens 233, mirror 235, mirror 235′) are water-cooled or air-cooled. Cooling water can be supplied by a heat exchanger located near the laser head 200 and dedicated to providing sufficient water flow to the laser head 200. In certain such embodiments, the conduits for the cooling water for each of the optical elements 220 can be connected in series so that the cooling water flows sequentially in proximity to the optical elements 220. In other embodiments, the conduits are connected in parallel so that separate portions of the cooling water flow in proximity to the various optical elements 220. Exemplary heat exchangers include, but are not limited to a Miller Coolmate� 4,available from Miller Electric Manufacturing Co. of Appleton, Wis. The flow rate of the cooling water is preferably at least approximately 0.5 gallons per minute.
FIG. 17E shows a �CUT SETUP/OPERATION SCREEN� display which provides information regarding the straight cutting operation of the apparatus 50 in which the laser head 200 makes a straight cut to a desired depth in the surface of the structure to be processed. The straight cut is preferably along one of the axes of the apparatus 50. A �Cut Status� field provides information regarding the status of the cut operation and corresponding instructions to the user. The starting position of the laser head 200 along the first-axis position system 130 and the second-axis position system 150 are provided in the �System Status� field. A �Cut Parameters� field provides information regarding various parameters associated with the cutting, including, but not limited to, the speed of motion of the laser head 200, the length of the cut to be made, and the LBU program number. The parameters can be changed as described above. The buttons 574 f,574 g labeled �Long Axis� and �Short Axis� are used to select either the first axis or the second axis respectively as the axis of motion of the laser head 200. The buttons 574 labeled �Auto/Dry Run,� �Cycle Start,� �Cycle Stop,� �Machine Reset,� and �Next� operate as described above.
A �Surface Keying Status� field provides information regarding the status of the surface keying operation and corresponding instructions to the user. The starting position of the laser head 200 along the first-axis position system 130 and the second-axis position system 150 are provided in the �System Status� field. A �Surface Keying Parameters� field provides information regarding various parameters associated with the cutting, including, but not limited to, the speed of motion of the laser head 200, the length of the key to be made along the first axis and along the second axis, the offset length that the apparatus 50 will increment between movement along the first axis and the second axis, and the LBU program number. The parameters can be changed as described above. The buttons 574 f,574 g labeled �Long Axis� and �Short Axis� are used to select either the first axis or the second axis respectively as the axis of motion of the laser head 200. The buttons 574 labeled �Auto/Dry Run,� �Cycle Start,� �Cycle Stop,� �Machine Reset,� and �Next� operate as described above.
