RPMC Lasers is your HeNe Laser Supplier. A HeNe laser is one of the gas laser types. A gas laser light source produces a laser beam by applying a high voltage electrical discharge through a gas (e.g., CO2, Helium-Neon, or Argon-Ion). The gas laser was the first continuous operation laser and the first laser to operate by converting electrical energy to a laser light output. There are many types of gas lasers. We currently offer a selection of Helium-Neon (HeNe / He-Ne) laser tubes and modules. These gas lasers feature a robust mechanical design, excellent beam quality, and a variety of configurations. Furthermore, HeNe laser wavelengths are available in the Green, Yellow, and Red spectral ranges, with output powers ranging from 2mW up to 20mW.
A helium neon laser (i.e. HeNe laser, he-ne laser) is a type of continuously operating, or continuous-wave (CW) gas laser. The gain medium is a 10:1 gas mixture of helium and neon, pressurized within a glass tube. Applying a DC current to electrodes on opposite ends of the HeNe tube excites helium gas atoms into metastable states. Thus, when excited, helium atoms can efficiently transfer energy to neon atoms with quite similar excitation energies leading to population inversion. Due to the multiple energy levels of neon gas atoms, multiple laser transitions (helium neon laser’s emitted wavelengths) are possible, providing green HeNe lasers, yellow HeNe lasers, red HeNe lasers, and even IR HeNe lasers.

Our He Ne Laser Products:
The stabilized HeNe lasers we offer boast an excellent TEM00 beam, robust mechanical design, and a long service life of up to 30,000 hours. 543 nm, 594 nm, and 632.8 nm (633 nm) wavelengths are available, with output power levels from 0.5 mW to 20 mW. Standard and customized models are available with a host of options including single-mode or multimode, random or linear polarization, Brewster window tubes, fiber-coupling, and frequency stability. We also offer HeNe laser power supplies. All models can be provided with either a laboratory HeNe power supply, or one of three OEM power supply versions. The tried-and-true HeNe laser has been around forever as a staple in the laser lab with their excellent beam quality and long service life. These proven, reliable HeNe lasers are readily available with quick turnaround, perfect as a drop-in replacement!
He Ne Laser Applications:
These HeNe lasers boast long life, low noise, and high-stability, with many customization options. Because of these features, HeNe lasers are perfect for alignment, Raman spectroscopy, Fabry Perot interferometry, holography, gas sensing, digital imaging, medical and biophotonics applications, other he ne laser experiments, and more!
He Ne Lasers vs Diode Lasers:
There have been many discussions around whether or not diodes will replace HeNe lasers. However, while this may be plausible for certain applications, the superior beam quality, long service lifetime, low noise, high stability, long coherence length and competitive helium neon laser cost ensures a solid foothold in applications where enhanced performance and excellent beam quality is critical.
