The laser back writing process (LBW) on the glass and quartz has been studied in the present work. For this purpose, a steel target was irradiated with Q-switched Nd:YAG laser pulses. As a consequence of the laser irradiation, the produced plasma is penetrated onto the glass and quartz substrates. The process was compared for two different samples. The effects of the pulse numbers and the laser fluence on the morphology and the target material penetration on the substrate were investigated. The results show that this process produces microchannels with the controlled dimensions (the depth and width) on the substrate. The presence of the nanoparticles (Fe and Cr ions on quartz and Fe ions on glass) is an important result of this process that can affect the microchannels' function. Irradiation parameters, including the number of pulses, the laser fluence, the pulse repetition rate, and the substrate material, affect the channel quality and the type and rate of the ion penetrated onto the substrates. The width of the channels for the quartz sample is greater than that of the glass sample, and also, more ions are deposited on the quartz substrate than the glass. The EDX and UV-Visible spectroscopies were used for studying the penetration rate and the type of ions present on the substrates. The surface profilometer and scanning electron microscopy were used to investigate the profile and the width of the affected area. X-ray fluorescence spectroscopy (XRF) was used to study the metal target's composition.
