Femtosecond Laser Microfabrication of Artificial Compound Eyes

Round 1

Reviewer 1 Report

Femtosecond laser processing technology shows great potential in the field of artificial bionic compound eye structures, because of its excellent precision, programmable design capabilities, and 3D processing properties. Particularly, the femtosecond laser micromachining can minimize damage to the surrounding area and facilitate ultra-high precision micro-nano fabrication. In this review paper, Chen et al. systematically introduced the operational principles of biological compound eyes, and also summarized the typical manufacturing methods for biomimetic compound eye structures. they also introduced the femtosecond laser technology for producing biomimetic compound eye. This review is very interesting and well-written, which will arouse a wide readership from photonics, materials, and physics. Therefore, I am pleased to recommend this manuscript for publication with minor revision. The following comments may help improve the manuscript.

1. In Figure 1, could the authors provide more examples of compound eyes in nature, not just the dragonfly?

2. When the abbreviation of MLA first appeared on page 2, authors should give its full name which is microlens array.

3. In Figure 8d, please remove the irrelevant Chinese character.

Reviewer 2 Report

Fan Zhang et al. have summarized the application of femtosecond laser technology in the production of biomimetic compound eye. And this review concludes by highlighting the current challenges and presenting a forward-looking perspective on the future of this evolving field. It is well written and interest to the researchers in the related areas. I would consider the paper for publication after minor revisions are made according to the following specific comments:

1.      Why fs laser beam is used for fabrication of Artificial Compound Eyes? Could nanosecond laser or picosecond laser achieve the same results?

2.      The discussion on future prospects lacks depth. Provide a more nuanced analysis of potential advancements of Artificial Compound Eyes. Discuss emerging trends, ongoing challenges, and propose potential research avenues that could shape the field in the coming years.

3.      One significant drawback is the absence of the author's insights and perspectives. The manuscript reads more like a compilation of summaries from various papers rather than an expert synthesis of the literature. It is crucial to infuse the text with the author's critical viewpoints, potentially addressing gaps in current research, proposing new directions, highlighting methodological limitations in the existing studies, and providing a more engaging and enlightening narrative for the readers.

4.      For the study of femtosecond laser fabrication and its applications, the authors may refer these recent papers: Nanoscale, 2023,15, 11247; Nanoscale 15, 15708, 2023;

5.      For more perfection, several language mistakes could be revised.

Reviewer 3 Report

As the author is well aware, the main parameters of femtosecond lasers include pulse energy, pulse repetition rate, pulse duration, wavelength, focusing power (NA of the focusing optics), Focus spot shape (Gaussian or other), and spatial pulse spacing. It is important to tabulate each parameter in a review paper to encourage quick understanding by readers. Although the author classified various technologies into categories, it would be better to organize the data from the literature again targeting key parameters.
