Multipass prism monochromator for coherent Raman spectroscopy

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...

Zusammenfassung:	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 x 10(-8) at a detuning of 200 cm(-1). It promises to be an important tool for coherent Raman spectroscopy.
