• Spindler and Hoyer ZL-150 Axial Zeeman Helium-Neon Laser (Gallery)

  The Spindler and Hoyer ZL-150 is an axial Zeeman two-frequency HeNe laser like those from HP/Agilent, but the output is right and left circularly polarized rather than horizontally and vertically linearly polarized and the split frequency is lower. It uses a standard commercial HeNe laser tube and a different locking technique but should have similar stability. Much more information on these lasers can be found in the chapter: Commercial Stabilized HeNe Lasers of Sam's Laser FAQ.
