Herriott Cell Mirrors

Herriott cells allow the construction of compact resonators by increasing the optical path of a laser beam inside the cavity by multiple reflections. For this purpose, they consist of two spherical mirrors of equal focal length. Heriott cells are used to shorten laser pulses.

One of the two resonator mirrors has a typically acentric bore, which serves as an inlet and outlet opening for, for example, the beam (or a process gas). The inlet and outlet sides each have a conical opening to prevent the beam from being clipped.
