a question about lasers, engineering homework help

A typical baseline capability for laser cutting in industry is the flat-bed profile cutting with CO2 laser and oxygen assist gas jet of 10-20mm thick mild steel at 2-3kW beam power and 50-100mms-1 cutting speed. Given this, describe in detail various ways in which it may be possible to extend the scales of the process from this baseline position. For each of the parameters that might be scaled, show how recent advances in laser cutting science and technology have already addressed some of these aspects. Use sketches to illustrate your answer.
