机译：Inexpensive highhyphen;speed dentist drill light chopper and its use in rejecting luminescence background from Raman spectra
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 10minus;6sec.
