Webb16 maj 2024 · Compared with a picosecond laser, a femtosecond laser can achieve higher quality CFRP drilling due to its smaller pulse width, but there are few studies on the effects of femtosecond laser parameters on CFRP drilling. Moreover, the cross-sectional taper of CFRP produced by laser drilling is very large. Webbuseful. Pulse duration broadening to the picosecond level is also a somewhat effective way to avoid optical damage and obtain a high average power without increasing the number of optical components, although the spectral linewidth of picosecond pulses, which is narrower than that of femtosec-ond pulses, limits their broadening efficiency. In ...
