Stabilized He-Ne Laser
We offer single- and dual-frequency stabilized lasers. Dual-wavelength lasers are produced with Zeeman frequency splitting and a wide range of difference frequency of optical components. A high frequency stability is provided by use of active and passive stabilization methods. Linear and orthogonal polarizations facilitate wide application of lasers in test and measuring equipment.
Single- and dual-frequency stabilized gas-discharge lasers offer a high stability of optical and difference frequencies and of the emission spectrum which enable their use as the key element in high-precision test and measuring apparatus.

1. A dual-frequency stabilized laser LHN-212-x emitting on orthogonally polarized components. The laser comes as a monoblock with a laser head and a power supply packaged in one housing. All structural elements and mirrors are sealed into a glass envelope. A built-in collimator permits easy alignment of optical systems incorporating a laser. and enables user operation at a long distance from a light source. |
