Multiple beam wide band CRDS cavity sensor and detector

A common multi-gas ring down detector (10) incorporates a cavity that has a piezoelectric mirror (20) and at least two displaced mirrors (26a,26b,28a,28b) to define two different transit paths (P1,P2) in the cavity. The two paths intersect at the piezoelectric mirror at different angles (A1,A2). Two...
