Designed for long life
Low noise and high stability
Excellent beam quality
Standard and customized models
Single mode or multi mode
Randomly or linear polarized
The LASOS® Helium Neon lasertubes and modules have a robust mechanical design, excellent beam quality and long service life of up to 30,000 hours. Standard and customized models are available in a large variety in the spectral range red, green and yellow with output powers between 0.5 and 20 mW. Options are single mode or multimode, randomly or linear polarized and Brewster window tubes for educational and scientific purposes.
Although the technology underlying He-Ne lasers is now over 50 years old, many manufacturers of high-precision measurement technology still rely on the excellent beam properties and unbeatable price-performance ratio.
The main applications for He-Ne lasers today are interferometric measurement technology and spectroscopy.
The properties and lifespan of a He-Ne laser are largely determined by the power supply used. In addition to power supplies from various manufacturers, LASOS also offers a range of its own He-Ne power supplies with an input voltage of 12 V and an operating current between 3.5 and 5 mA. We recommend LASOS He-Ne power supplies to all our customers in the OEM sector who operate LASOS lasers in the DC range.
Customized solutions for specific applications can be provided.

Glossary of terms
Side lines (SL)
Unwanted emission besides the nominal wavelength value, often disturbing in spectroscopy and interferometry. Can be suppressed by special mirror technology.
Polarization switching (PS)
Sudden changes of the polarization of different modes espacially in short tubes. Particularly disturbing when HeNe laser tubes are used in frequency stabilized operation. Can be eliminated by special selection process.
Two longitudinal modes (LM)
Tube supports exact two orthogonally polarized longitudinal modes. Required for special methods of frequency stabilization.
Magnetic field stability (MF)
The above characteristics are also guaranteed in the presence of a strong magnetic field up to 3 G
Split frequencies (SF)
Frequency split of He-Ne laser modes in the presence of a strong magnetic field (> 200 G). Can be used for obtaining extremely high frequency stability. LASOS® has been successful in developing tubes with specific split frequencies for defi ned magnetic fields.
Accessory
Operating a He-Ne laser requires a compatible power supply unit. LASOS offers matching power supplies for all laser models, both with DC input (12V and 24 V) and with AC input (100…230 V). A distinction is made between OEM power supplies and power supplies for laboratory use. OEM power supplies are only designed for installation.
For power supplies with a 12 V input and operating currents up to 5 mA, we recommend LASOS own He-Ne power supplies from the LGN 9101 series.
