Abstract
Our purpose is to develop a compact focus head for Nd:YAG laser processing in restricted spaces. The focusing assembly is a scaled- down "conventional" focus head with two conventional planoconvex focusing lenses and an outer diameter of 10 mm. Thermal and optical analyses are carried out to optimize the gas cooling design and the optical configuration of the focus head. Power capacity and processing tests confirm the capability of the focus head to produce good quality welds at powers up to 1400 W. Although extended life tests are not carried out, neither the head nor its optics show any signs of damage after approximately 40 min of processing.
