Microdrilling of Sheet Materials with Femtosecond Laser Pulse Shaped by Computer Generated Hologram

By: Hayato Kawashima, Masahiro Yamaji, Jun’ichi Suzuki, Shuhei Tanaka We have developed a three-dimensional (3D) femtosecond laser processing method using a computer generated hologram (CGH) that generates a 3D structure inside transparent materials. Since 3D structure can be formed simultaneously with femtosecond laser pulses shaped by a CGH, our method is high efficient, and it […]
