Defence advisory roles

Before their tenure on the institute's leadership team, between 2011 and 2016 one member was part of either a 'special expert group' or an 'expert group for major projects' under the 863 Programme.^[1] The 863 Programme, which operated from 1986 to 2016, was a major Chinese government fund aimed at developing advanced technologies for both civilian and military use. The fund was jointly administered by the Chinese Ministry of Science and Technology (MOST), the then General Armaments Department of the People's Liberation Army (PLA), and the former Commission of Science, Technology and Industry for National Defence (COSTIND).^[2] While it is unclear which major project the researcher advised on, the one most closely aligned with their expertise at the time pertained to laser technology. Laser technology research under the 863 Programme was overseen by COSTIND and focused on 'high-performance and high-quality laser technologies, applying the results to production and driving the development of technologies and sciences such as pulsed power technology, plasma technology, new materials, and laser spectroscopy'.^[3]

Other members of the institute's leadership have almost certainly not served on defence-related expert committees. As the data reviewed are complete, up-to-date and cover all members of the leadership team, this assessment is made with high confidence.

Defence awards

Available information indicates that researchers affiliated with the Shanghai Institute of Optics and Fine Mechanics have received three separate defence awards over time. These include one Military Science and Technology Progress Award, one Military Science and Technology Progress Award granted by the General Armaments Department of the PLA, and one title of Advanced Individual in Collaboration and Support of National Defence Science and Technology Industry.^[4]

Of the identified awards, the date could only be verified for the Military Science and Technology Progress Award. According to available data the award was granted in 2012 while the researcher was employed by the Shanghai Institute of Optics and Fine Mechanics.^[5] Dates are not known for the other two awards^[6] and our analysis was therefore unable to confidently connect them to work conducted at the Shanghai Institute of Optics and Fine Mechanics. Even though the researchers had spent the majority of their careers at the institute, some periods were spent at other institutes.^[7]

While researchers and projects linked to the Shanghai Institute of Optics and Fine Mechanics have received at least one defence award prior to 2021, there are probably no awards that have been granted in recent years. However, outdated and insufficient data prevent confirmation of award dates. This assessment is therefore made with medium confidence. Awards granted prior to researchers' affiliation with the institute or more recently cannot be fully ruled out.

Defence funding

Between 2021 and 2025, researchers from the Shanghai Institute of Optics and Fine Mechanics authored 34 publications funded by Chinese defence entities, placing the institute in the 55^th percentile among the CAS institutes included in this analysis. Of the 3,274 authors affiliated with the Shanghai Institute of Optics and Fine Mechanics who published during this period, 108 (3 per cent) had at least one defence-funded publication. However, it is not possible to attribute specific funding to individual researchers based solely on publication data.

Defence laboratories

No publicly available information suggests that this institute hosts or is affiliated with any known defence laboratories. However, one laboratory, not categorised as a defence laboratory, referenced links to defence activities on its Chinese‑language website. General references to promoting national security or defence are common on CAS laboratory websites. These statements often serve as broad affirmations of alignment with national policy objectives – a routine expression of support for government priorities that can be important for maintaining institutional standing, access to funding or official recognition – rather than firm evidence that the laboratory conducts defence-related research.

Name	Joint Laboratory of High-Power Laser Physics [高功率激光物理联合实验室]
Research topics	Operation of ShenGuang-II Laser Facility, high-powered lasers, physics experimental research
Defence ties	According to its website, this laboratory has been valued over the years by the 'General Armament Department, [and] the former National Defence Science and Technology Commission'. Both organisations have since been restructured and are now known as the Equipment Development Department of the Central Military Commission, and the State Administration for Science, Technology and Industry for National Defence, respectively - two key actors in China's defence apparatus. The use of their former names suggests that this relationship may not have continued after their 2008 and 2016 reforms, or that the relationship has simply not been mentioned publicly. The laboratory's website also notes that it considers technology development for 'national defence applications', and has made 'important contributions to promoting our country's national defence'.[8]

Military-technology patents

Between 2021 and 2025, the Shanghai Institute of Optics and Fine Mechanics was granted 11 military-technology patents, placing it in the 80^th percentile among the CAS institutes included in this analysis. A total of 66 inventors affiliated with the institute were listed on these patents.

Research collaboration with defence entities

Between 2021 and 2025, researchers from the Shanghai Institute of Optics and Fine Mechanics co-authored 276 publications with at least one Chinese defence entity, placing the institute in the 41^st percentile among the CAS institutes included in this analysis.

These collaborations include 68 publications with PLA academic institutions, 100 with defence laboratories, 113 with members of the Seven Sons of National Defence, 45 with members of the Seven Sons of Ordnance Industry and 3 with defence conglomerates.

Of the 3,274 authors affiliated with the Shanghai Institute of Optics and Fine Mechanics who published during this period, 476 (15 per cent) had at least one defence-related collaboration.
