Abstract

A wavelength meter capable of measuring the absolute wavelength of pulsed laser radiation to 1 part in 106 is described. It consists of five Fizeau, or optical-wedge, interferometers. The fringes from a standard (He–Ne) and an unknown laser are captured by a television camera interfaced with a microcomputer that calculates the wavelength.
