Abstract
A novel precision wavemeter is presented with a resolution of better t han 0.01 nm. A Sagnac interferometer with two diffraction gratings for ms the basis of the instrument. Using spatial heterodyning techniques and a CCD camera/frame grabber data acquisition system allows fast com puter control and power spectrum analysis. The mode structure and mode hopping characteristics of a typical laser diode were examined as a f unction of diode injection current. (C) 1998 Elsevier Science Ltd. All rights reserved.
