(a) PVC irradiations at 1030 nm with N = 25, 40 and 65 pulses/spot-area from left to right and f = 5 kHz. (b) PET irradiations at 1030 nm with N = 60 pulses/spot-area and f = 2.5 kHz, 110 and 125 pulses/spot-area and f = 100 kHz from left to right. (c) PP irradiations at 1030 nm with N = 125 pulses/spot-area and f = 200, 250 and 300 kHz from left to right. The scale bar shown in (a) is applicable to (b) and (c) too. (d) PVC irradiation at 1030 nm with N = 125 pulses and f = 1 MHz. (e) PET irradiation at 1030 nm with N = 250 pulses and f = 100 kHz. (f) PP irradiation at 1030 nm with N = 400 pulses/spot-area and f = 1 MHz. All the presented irradiations were performed at a fluence value of 1.70 J/cm².
