Abstract

A simple Lloyd’s mirror interferometer and a CCD photodiode array make a compact Fourier transform wavemeter for pulsed lasers. A transformation from the nonlinear spatial sampling of the diodes to a linear temporal series is described that sharpens the distribution in the spectral domain and permits long diode arrays to be used in the interferometer. Tests with a tunable red dye laser show that the wavemeter has an accuracy of ~ 2 cm⁻¹ and the sensitivity to record untuned superradiant emission from the dye as well as frequency doubling in the ultraviolet.
