This stabilization technique was also verified for a larger HeNe laser with a lower free spectral range. While not optimized for this configuration and laser, we demonstrated fractional frequency fluctuations below 1×10 -8 with 3.5 mW of usable output power. This is useful for multi-axis systems or systems employing fiber coupling.

If you use a non-linear crystal, you can double the frequency of a YAG laser. In this case, the 1064 nm has been doubled in frequency to 532 nm, which is green. Nd:YAG is now often used in fiber lasers, and with some doping and changing of the YAG material, you can get almost any wavelength between 1047 nm and 1319 nm.

HeNe Laser Supplier | He-Ne Laser Tubes, Modules & Power Supplies

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.

HeNe Lasers: Pros and Cons

Most powerful HeNe lasers emit 35 to 50 mW of output power. This is low comparing with a 100 mW to 200 mW TEM00 output from some semiconductor lasers. Even frequency stabilized 633 nm lasers emit 70 mW to 100 mW of narrow-linewidth power. Very bulky. A 35 mW output power HeNe laser is about 1 meter long.
