Vertical high‐precision Michelson wavemeter

Abstract:

We have designed and tested a traveling, Michelson‐type vertical wavemeter for the wavelength measurement of tunable continuous‐wave lasers in the visible part of the spectrum. The interferometer has two movable corner cubes, suspending vertically from a driving setup resembling Atwood’s machine. To reduce the fraction‐of‐fringe error, a vernier‐type coincidence circuit was used. Although simple, this wavemeter has a relative precision of 3.2 parts in 109 for an overall fringe count of about 7×106.
