Gas Lasers

There are many types of gas lasers. We currently offer a selection of both Helium-Neon (HeNe / He-Ne) and Argon-Ion (Ar-Ion) lasers and modules. These gas lasers feature a robust mechanical design, excellent beam quality, and a variety of configurations. Furthermore, wavelengths are available in the Blue, Green, Yellow, and red spectral ranges, with output powers ranging from 0.5mW up to 35mW.Gas Lasers - HeNeGas Lasers - Argon-Ion

He-Ne Lasers:

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 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 atoms into metastable states. Thus, when excited, helium atoms can efficiently transfer energy to neon atoms with quite similar excitation energies. Due to the multiple energy levels of neon atoms, multiple laser transitions (helium neon laser wavelengths) are possible. 

The HeNe lasers we offer boast an excellent TEM00 beam, robust mechanical design, and a long service life of up to 30,000 hours. 543nm, 594nm, and 632.8nm wavelengths are available, with output powers from 0.5mW to 20mW. Standard and customized models are available with a host of options. Therefore, you can choose between include single-mode or multimode, random or linear polarization, Brewster window tubes, and fiber coupling. All models can be provided with either a laboratory HeNe power supply, or one of three OEM power supply versions. These HeNe lasers boast long life, low noise, and high-stability, with many customization options. Because of these features, HeNe lasers are perfect for spectroscopy, interferometry, holographymedical applications, 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, and competitive cost of HeNe lasers ensures a solid foothold in applications where excellent beam quality is critical.

Argon-Ion Lasers:

Our Argon-Ion lasers are compact, economical, and boast an excellent beam quality, long term stability, low noise operation, and a broad blue to green spectral range. Available emission lines range from 454nm to 514nm, with output powers up to 35mW. Choose between single wavelength or multi-wavelength versions, as well as a dual-line version, perfect for photo printing applications in the AGFA d-lab.2 and d-lab.3 printers.

All laser tubes have an internal mirror with a vacuum-tight, hard-sealed and integrated resonator construction. Because of this, optimized life time and power stability are provided. Several options for cooling, OEM power supplies, and a remote control are available. Finally, the laser mirrors are adjusted and fixed, providing maintenance-free operation with no need for readjustment in the field!
