Opacity Corrections for Resonance Silver Lines in Nano-Material Laser-Induced Plasma

Round 1

Reviewer 1 Report

This manuscript describes a scheme to obtain original spectral shape from measured spectral shape distorted by the opacity effects. I recommend this paper is published in the journal. I found several typos in the manuscript. 

On line 41, "tips" may be dips.

On line 76, "352 and 355 nm" should be "532 and 355 nm"

On line 118, "nan-material" should be "nano-material."

Reviewer 2 Report

The manuscript is interesting. It describes a nice work.

There is a possible big problem about publishing this paper. It presents work similar to author’s previous works. Among others, the newest one, see reference [14], (also about silver): “A three orders of magnitude enhanced emission intensity from the nano-based target over the bulk target was achieved at lower levels of laser irradiation.”

However, I think that paper is interesting enough to deserve publication, after some minor corrections.

This paper offers “Opacity corrections” for some of the silver lines based on other silver lines, a point which importance should be maybe better explained and/or more accented.

75  “In the experiments, a Nd:YAG laser device(Quantel model Brilliant B) operates at the fundamental 75 wavelength of 1064 nm and the two harmonics at 352 and 355 nm….” – 532 and 335 nm ?

95  “The nanoparticle size equals 95 ± 10 nm, as confirmed from measurements with a transverse electron microscope.”  - Transmission microscope?

117   The introduced correction procedures are based on precise knowledge of “true” electron density of the nan-material plasma – what is nan-material plasma? The whole sentence should be made more clear.

Dear reviewer,

Thank you for your review. We revised the manuscript accordingly, and the edits are indicated in blue.

- added a sentence just before Section 2 

- edited the sentence in 2nd paragraph after Figure 5, and added a sentence at the end of that paragraph.

- corrected the typos
