"The laser beam is focused between the two prongs of the quartz tuning fork. When light at a specific wavelength is absorbed by the gas of interest,
either forwards or backwards along the laser beam it is possible to distinguish between left and right handed molecules with an accuracy of up to several tens of per cent rather than a fraction of a per cent.
and uses two different laser beams to excite mercury atoms and monitor blue shifted atomic fluorescence.
The laser beam is not visible to the naked eye. Gesn absorbs and emits light in a wavelength range of about 3 micrometres.
Now, efficient and compact laser sources are at hand emitting in the near-infrared on multi-watt level (CW operation) with a narrow-band spectrum and a stigmatic, nearly Gaussian laser beam
