A multipass, Brewster prism monochromator that is an effective laser beam separator is described. Fourteen passes through the prism of the monochromator produce a resolution of 4 cm−1 with a throughput of 63%. Larger throughputs are obtained for fewer passes and a poorer resolution. The device is tunable and has an extinction coefficient of 2 × 10−8 at a detuning of 200 cm−1. It promises to be an important tool for coherent Raman spectroscopy.
