He-Ne Lasers of Visible Range

Plasma， JSC， offers 25 models of He-Ne lasers of HN and LGN series with emission power from 0.5 to 70 mW in single mode or from 5 to 100 mW in multimode regime. There are models with polarized and non-polarized emission.

He-Ne Lasers of IR Range

The series of He-Ne lasers of IR range includes 11 models with emission power of multimode emission from 1 to 25 mW at wavelengths 1.15， 3.39， 3.5， 5.4 mm. He-Ne lasers possess all the advantages of low-power monochromatic emission at the new spectral lines， coinciding with the lines of absorption of a series of ecologically hazardous wastes produced by industrial facilities.

Stabilized He-Ne Lasers

We produce and sell single- and dual-frequency stabilized He-Ne lasers. Dual-frequency lasers with Zeeman frequency splitting and wide range of the difference frequency values (from 1.5 MHz to 4.5 MHz) of the optical emission components. High stability of emission frequency is provided by active and passive methods of stabilization. Linear and orthogonal emission polarizations provide for the wide opportunities of the application in control-measurement systems with the highest accuracy.
