You're aware that a high powered laser that emits invisible laser radiation is a "class 4" laser in which exposure to direct and reflected laser radiation represents substantial risk, and which therefore requires considerable attention paid to its safety measures, including potentially a complete light-tight enclosure (no gaps, no direct escape paths for light) and stringent interlocking ... right?
The safety standard that applies to your installation depends on where you are in the world, but regardless, something is going to have to be done about it.
Those safety measures plus the inherent expensiveness of high powered laser equipment in general mean that "cheap" is not going to happen safely.
Trumpf is well regarded. They are NOT cheap.
