Refractive Index Abbe Value - Precision Micro-Optics

It also has lasing transition in IR, orange and green. An HeNe laser typically has a minimum beam diameter of 2 w0 = 1 mm. The wavelength of the HeNe laser is λ = 0.63 μm = 0.63 × 10 −3 mm. The full divergence angle calculated by Eq. (2.5) is roughly 10 −3 radians = 1 milliradian (i.e., 0.06°). At a distance of 10 m from the laser, the beam diameter will thus be only 1 cm.

This is the ideal reference source because its wavelength is well-known and fixed by fundamental atomic structure. To achieve the highest accuracy, the model 671A uses a single-frequency HeNe laser that is stabilized using a precise balanced longitudinal mode technique. A standard HeNe laser is used as the wavelength reference in the 671B system. Helium-Neon lasers have a wavelength of 633 nm and are able to shine through water with minimal loss of laser power. HeNe vibrometers are therefore indispensable if there is a layer of water between the vibrometer and the vibrating measurement object. HeNe lasers are the industry norm due to their excellent wavelength stability compared to solid-state or diode lasers.
