We report an invisible two-dimensional (2D) barcode embedded into a synthetic fused silica by femtosecond laser processing using a computer-generated hologram (CGH) that generates a spatially extended femtosecond pulse beam in the depth direction. Wh

We report on a curved waveguide fabrication using femtosecond laser processing with a glass hologram. We design and produce a glass hologram that transforms femtosecond laser beam into a half-ring beam. The half-ring beam generated by the glass holog

We report microdrilling of sheet materials, especially fused silica glasses by femtosecond laser processing with a computer generated hologram (CGH). We design a CGH with long-focal-depth to efficiently extend optical damage in the depth direction re
