What This ECCN Covers

ECCN 6C005 controls "laser" materials — for example synthetic crystalline laser host materials in unfinished form (such as titanium-doped sapphire) and certain other gain media meeting the criteria in the entry. These materials are the heart of high-performance lasers and are controlled for National Security and Anti-Terrorism reasons.

Who needs to check this?

Producers and exporters of laser crystals, gain media, and unfinished laser host materials for the photonics and directed-energy markets.

Compliance tip

Control applies to specific host materials and forms named in the entry — confirm your material and its processing state against those criteria. Coordinate with the laser entry (6A005) for finished devices, and verify the NS and AT columns.
