title: Multiple-wedge wavemeter for pulsed lasers.
abstract: A wavelength meter capable of measuring the absolute wavelength of pulsed laser radiation to 1 part in 10(6) 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.
