Abstract

An inexpensive dentist drill laser beam chopper is described. The chopper, which can be tuned for a chopping frequency from 100 Hz to 400 kHz, is compact, stable, and easily constructed. The usefulness of the dentist drill laser beam chopper is demonstrated in a technique for the suppression of luminescence background in Raman spectra. The technique is shown to be capable of almost complete suppression of luminescence with decay lifetimes greater than 10 ^-6 sec.
