High-Energy Electron Emission Controlled by Initial Phase in Linearly Polarized Ultra-Intense Laser Fields
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsIn the article entitled “High-Energy Electron Emission Controlled by Initial Phase in Linearly Polarized Ultra-Intense Laser Fields,” the authors have performed numerical simulations to describe the spatiotemporal and spectral characteristics of the nonlinear Thomson radiation emitted by relativistic electrons in a tightly focused linearly polarized laser field. The author’s calculations suggest that precise control of the Laser’s initial phase is crucial in manipulating the characteristics of the radiation emitted by the electron interacting with the intense laser field.
Comments:
- Authors should provide a generic definition of the carrier-envelope phase (CEP) in the introduction section of the manuscript.
- Authors should consider providing the MATLAB program code in the supporting information.
- More relevant references can be included in the manuscript.

Reviewer 2 Report
Comments and Suggestions for AuthorsIn this report authors discussed the effect of the initial Phase in linearly polarized ultra-intense laser fields for the generation of high-energy electron emission. This work is completely simulation-based results, however it is interesting for applied sciences readers. I have given my comments below before going next step.
- All the calculations and results are simulation. Can authors suggest experimental setups to practically visualize these results? Also authors can discuss the challenges, limitations, and conditions when it comes to experiments.
- Authors can provide more details on the future scope of this work and why it is necessary in the current research.
- Authors have focused on a very narrow topic in this manuscript, as a result end up with very few references.
- All figures are not clear and concise.
- Authors should mention how tightly we have to focus the beam and how matter affects the initial phase of the beam during interaction.
- Could we see any changes in the mode when we change the transverse phase of the incident light without changing its polarization?
- What kind of results can we expect when we use elliptically polarized light?

Reviewer 3 Report
Comments and Suggestions for Authors- In Introduction section, a citation to the seminal work of classical Thomson scattering theory is missing.
- In Introduction section. Are there no further references or previous studies on how the carrier envelope phase (CEP) affects the phase matching conditions?
- There is a lack of citations in the state of art, there isn't more work related or previous works in this direction?
- In Materials and Methods section, Is there a mathematical justification to extend the diffraction angle to the fifth order? Or only is a numerical consideration?
- In the Materials and Methods section, a citation to the Lienard-Wiechert theory framework is missing.
- In Figure 3 is not clear the difference between the plots an the angles presente in the corresponding projections.
- In Figure 4, what does mean the colours in the plots?
- In Figure 5 it could be separeted the plot (i) to be more clear in the discussion of the correlation?
- Many plots are separate, it's best to put them on the same page to clarify the discussion. The presentation of the figures needs to be improved so the reader can follow their discussion and description.
- This statement of lines (341-343) is true “The maximum radiation intensity of the electron energy increases four times with the electron energy and the threshold frequency of the laser”, because in the corresponding figure something else can be observed.
- How do you arrive at the statement: "Comparative analysis of the three graphs reveals a quadratic increase in the maximum radiation intensity with electron energy" compared to the corresponding plots? This statement is unclear.
- Line 355 is mispelling “controlled phase variation. meanwhile”.
