Abstract

We demonstrate an asymmetric multipass cavity with meter-scale optical path lengths in a volume of 68 cm3 and diameter of 5.24 cm. The cavity is machined from copper and coated with gold. For the characterization of the optical path length in the cavity, we perform a pulse-delay experiment by measuring the time delay between a laser pulse coupled into and out of the cavity. A midinfrared quantum cascade laser is employed as the source. By rotating the cavity, a variety of reentrant patterns and path lengths ranging from 2.0 to 6.0 m can be obtained with straightforward optical alignment.
