Why surface quality matters in a THz source
A Pécs study examines how a crystal’s microstructure relates to terahertz source performance.

A manufacturing question becomes a physics question
Surface quality becomes particularly important when it affects optical interaction. The Pécs researchers’ 2025 work investigates this connection in a microstructured lithium niobate THz source.
What should be investigated next?
Evaluating surface topography alongside source performance can inform the next machining iteration. A research result should not be treated as a universal manufacturing tolerance or a finished-product promise.
