The global photonics community depends on a careful balance: protecting sensitive technologies while enabling scientific progress, commercial innovation, and international collaboration. One of the primary mechanisms for maintaining that balance is the Wassenaar Arrangement, a voluntary international export control regime comprising 40+ participating countries.
The Wassenaar Arrangement establishes controls on transfers of conventional arms and dual-use goods and technologies, items that have both civilian and military applications. Member countries propose updates to control lists, which are reviewed and adopted by consensus. These updates are then implemented through national export control systems. Because decisions must be unanimous, the process is deliberate and highly technical, relying on deep subject-matter expertise from government, industry, and scientific organizations.
SPIE plays a key role in this ecosystem. Working closely with industry partners, researchers, and government stakeholders, SPIE helps identify areas where controls may be outdated, unclear, or misaligned with current technology. From there, it supports the development of technically sound proposals and helps shepherd them through the process.
Recent successes demonstrate how targeted, well-crafted proposals can modernize controls without undermining their security intent. With coordination support from SPIE, two United States government proposals were advanced through the Wassenaar process and ultimately adopted, improving clarity and usability in laser-related controls.
Clarifying Controls on Tunable Lasers
The first adopted proposal, 6.A.5.c.3., introduced a decontrol note for tunable lasers. Tunable lasers are essential tools across research, telecommunications, environmental sensing, and medical diagnostics because they allow users to precisely adjust the emitted wavelength.
Prior to this update, the absence of clear language created ambiguity around whether certain tunable systems fell under export controls, even when their capabilities did not align with the intended scope of restriction. This uncertainty imposed unnecessary compliance burdens on researchers and manufacturers and risked slowing legitimate scientific work.
The newly adopted decontrol note resolves that ambiguity. By explicitly identifying categories of tunable lasers that should not be controlled, the revision ensures that export controls remain focused on genuinely sensitive capabilities while allowing widely used, lower-risk systems to move more freely across borders. The result is a more precise regulatory framework that better reflects how tunable lasers are actually used in practice.

The second proposal, 6.A.5.a.6., revised laser output power control thresholds and introduced a new control range under 6.A.5.a.6.a.3..
Laser performance has advanced significantly in recent years, with commercial systems outside of Wassenaar compliant countries now routinely achieving higher output powers and efficiency. Existing thresholds had not kept pace with these technological developments, leading to over-control of widely available commercial systems that no longer represent sensitive capabilities.
The updated thresholds recalibrate the control regime to better align with current technological realities. By introducing a new control range, the revision brings control levels closer to releasing standard industrial lasers. In this rapidly growing field of industrial lasers, SPIE will continue to advocate for the community utilizing the most current market data available.
Both of these proposals must be adopted by your national government before you can export using the new control standards.
A Collaborative Model for Effective Policy
These two adopted proposals highlight the importance of collaboration between government and the technical community. Export controls are most effective when they are informed by real-world expertise, ensuring they are both enforceable and appropriately targeted. SPIE is prepared and well-positioned to assist in making sure the photonics industry and the research community’s interests are represented in these discussions.
As photonics technologies continue to evolve, this model of collaboration will remain essential. Thoughtful updates like these not only protect global security interests but also ensure that innovation in optics and photonics can continue to thrive.
