Abstract

Material processing with high repetition rate ultra-short laser pulses with intensities higher than 10\(^{13}\) W/cm\(^{2}\) may lead to the X-ray emission dose exceeding allowed dose limits. We have investigated a worse-case exposure scenario, in which laser processing parameters were tuned to maximize X-ray yield. Use of double pulse regime leads to increase of the X-ray yield up to two orders of magnitude compared with the single pulse regime. \(H^{\prime }\)(0.07) and H*(10) dose rates were measured using X-ray spectrometer and electronic dosimeter. Maximum dose rates at 35 cm distance from the X-ray source calculated using spectrometer data exceeded 1 Sv/h and 9 mSv/h, respectively. Dose rates measured using the dosimeter were lower. The difference is attributed to narrower X-ray spectral range detectable by dosimeters, which may lead to underestimation of exposure doses in the laser processing laboratories. The presented method might be used as an example to evaluate X-ray yield and optimize measures of radiation protection.
