“… 18 – 20 The optical arrangement of DLIP holography required a complex setup and specific exposure angles of the incident beams for accurate fabrication. 21 Recently, a single-pulse Denisyuk DLIP holography method was developed to form surface gratings. 7 , 12 Light absorbing materials such as inks and metal thin films were coated on glass substrates and laser ablation was utilized to selectively remove the material from localized regions.…”

“…Surface gratings can also be written by complex techniques such as E-beam lithography (EBL) and focused ion beam (FIB) milling. − However, these approaches are high-cost, low-throughput, and labor intensive . To overcome these limitations, direct laser interference patterning (DLIP) in split-beam off-axis mode has been developed to fabricate surface patterns . This approach involves laser pulses (∼300 mJ/cm 2 ) to selectively modify thin films made out of polymers, aluminum zinc oxide, nickel, and steel. , For example, the use of a frequency-quadrupled diode-pumped solid-state laser (6 ns, 266 nm, 20 mJ) allowed direct interference patterning of light-emitting fluorene polymer .…”

Holography plays a significant role in applications such as data storage, light trapping, security, and biosensors. However, conventional fabrication methods remain time-consuming, costly, and complex, limiting the fabrication of holograms and their extensive use. Here, we demonstrate a single-pulse laser ablation technique to write parallel surface gratings and Fresnel zone plates. We utilized a 6 ns high-energy green laser pulse to form interference patterns to record a surface grating with 820 nm periodicity and asymmetric zone plate holograms on 4.5 nm gold-coated substrates. The holographic recording process was completed within seconds. The optical characteristics of the interference patterns have been computationally modeled, and well-ordered polychromatic diffraction was observed from the fabricated holograms. The zone plate showed a significant diffraction angle of 32° from the normal incident for the focal point. The nanosecond laser interference ablation for rapid hologram fabrication holds great potential in a vast range of optical devices.
