Abstract
The paper presents some recent developments in sensor technology for o n-line diagnostics and control of laser materials processing. The resu lts focus on three topics e.g. pyrometric temperature measurements and on-line output power control of cw-lasers quality control using diffe rential reflectometry short time detection techniques for process moni toring of laser beam interaction with materials during short (50 ns) a nd intense (MW/cm2 to GW/cm2) laser pulses.
