P3-71: VISIBLE LASER

Additional Info

  • ID Code: P3-71
  • Purpose: See the inside of a laser, observe the spectrum of light
  • Description: The case has been removed from a HeNe laser and has been replaced by a clear plastic tube, so that the optical parts can be seen. A flat white tab has been installed at the end so that the light leaving the laser strikes the tab. Using hand-held diffraction gratings, the spectrum of the light inside and outside the laser tube can be seen, allowing observation of the optical effect of the lasing action. The light inside the tube can be seen through a series of slits along the tube's length. The single wavelength of light in the external beam can be seen as the red dot on the top of the spectra above.
