The global market for laser material processing systems is rapidly increasing over the past few years[1]. From laser cutting to laser drilling and laser marking, high power ultrashort pulse lasers are versatile tool for production. Plasma generation during laser processing with ultrashort laser pulses puts the risk of unwanted X-ray radiation in the range of several kilo electron volts. We performed experiments to detect the generated X-rays(soft and hard X-rays between 200eV to 10,000eV) using X-ray camera while processing different solid materials and investigate the exposure safety limits[1,2].
