Láser He-Ne, set básico

Num.Producto: P2260701

Principle

The difference between spontaneous and stimulated emission of light is demonstrated. The beam propagation within the resonator cavity of a He-Ne laser and its divergence are determined, its stability criterion is checked and the relative output power of the laser is measured as a function of the tube's position inside the resonator and of the tube current. The following items can be realised with advanced set 08656-02. By means of a birefringent tuner and a Littrow prism different wavelengths can be selected and quantitatively determined if a monochromator is available. Finally you can demonstrate the existence of longitudinal modes and the gain profile of the He-Ne laser provided an analysing Fabry Perot system is at your disposal.

Benefits

  • set up and run a laser, that is by now classic, from its constituting elements
  • get a feel for the delicate adjustments necessary to achieve lasing conditions
  • dicover the way many parameters can influence the output of this gas laser

Tasks

  1. Set up the He-Ne laser. Adjust the resonator mirrors by use of the pilot laser (left mirror: VIS, HR, plane; right mirror: VIS, HR, R = 700 mm).
  2. Check on the stability condition of a hemispherical resonator.
  3. Measure the integral relative output power as a function of the laser tube's position within the hemispherical resonator.
  4. Measure the beam diameter within the hemispherical resonator right and left of the laser tube.
  5. Determine the divergence of the laser beam.
  6. Measure the integral relative output power as a function of the tube current.

The He-Ne laser can be tuned using a BFT or a LTP. Longitudinal modes can be observed by use of a Fabry Perot Etalon of low finesse. Remark: These points can only be covered quantitatively if a monochromator and an analysing Fabry Perot system are available.
