Metrics
“Cites per paper” is a two-year cited-by rate computed from OpenAlex. It is not a Clarivate Journal Impact Factor — we neither compute nor license that metric. Citation rates differ enormously between fields, so compare within a discipline.

Frequently asked
Is Chinese Optics Letters a predatory journal?
Our screening does not flag Chinese Optics Letters. That is not a guarantee of quality — it means the venue is not on Beall's archive (frozen since 2017) and does not match our name-pattern heuristic. It is listed in Scopus, Web of Science, PubMed, which is a positive signal.
Is Chinese Optics Letters indexed in Scopus or Web of Science?
Per our venue index, Chinese Optics Letters appears in: Scopus, Web of Science, PubMed. Index membership changes over time — confirm on the index's own site before relying on it.
What is the impact factor of Chinese Optics Letters?
Papers in Chinese Optics Letters are cited about 4.0 times each within two years of publication, and Scimago places it in Q2, with an h-index of 45. Those are the open equivalents: the Clarivate Journal Impact Factor is a proprietary metric we neither compute nor license, so we show the two-year citation rate and Scimago quartile instead — they answer the same question of how heavily the journal is cited. A citation rate is a property of a field as much as of a journal.
What Scimago quartile is Chinese Optics Letters (Q1, Q2, Q3, or Q4)?
Scimago places Chinese Optics Letters in Q2 for its subject category. Quartiles split the journals in a field into four equal groups by SJR, so Q1 is the most-cited quarter and Q4 the least; Chinese Optics Letters is cited about 4.0 times per paper over two years, with an h-index of 45. A journal is ranked per subject category, so one spanning several fields can sit in different quartiles depending on the category.
What is the Web of Science (JCR) quartile of Chinese Optics Letters?
The Web of Science quartile comes from Clarivate's Journal Citation Reports (JCR), a proprietary product we neither license nor compute — so we cannot state a JCR quartile for Chinese Optics Letters. The open equivalent is its Scimago quartile, Q2, derived from Scopus citation data. Because JCR ranks against Web of Science and Scimago against Scopus, the two can differ, so check Clarivate's site directly if you need the JCR quartile specifically.
Is Chinese Optics Letters open access?
We hold no reliable open-access classification for Chinese Optics Letters. Check the journal's own site for its access model and any article processing charge.
