As a new and emerging technology, the 2µm laser module has been gaining considerable attention due to its application in modern communication systems. Another consideration behind interest from experts in the field is the better safety profile of the 2μm wavelength. Light at this wavelength is absorbed more efficiently by water in biological tissues, and this translates to minimal risk for deep-tissue absorption. Thus, a 2µm laser module can accommodate higher power levels with confidence that the operator is safe.
