Abstract
We have built a high-accuracy wavelength meter for tunable lasers using a s canning Michelson interferometer and a reference laser of known wavelength. The reference laser is a frequency-stabilized diode laser locked to an ato mic transition in Rb. The wavemeter has a statistical error per measurement of 5 parts in 10(7), which can be reduced considerably by averaging. Using a second stabilized diode laser, we have verified that systematic errors a re below 4 parts in 10(8). (C) 2001 American Institute of Physics.
