Synopsis

Precision lambdameter for optical fiber laser wavelengths

This concise work explains a high-accuracy instrument used to measure the wavelength of infrared single-mode diode lasers for fiber communications.

The book describes a practical, vacuum-toperated system based on a scanning Michelson interferometer. It covers how fringe counting and careful alignment yield very small wavelength uncertainties, suitable for standards work with 1.3 and 1.5 micrometer sources. The discussion includes instrument design choices, alignment procedures, and how environmental factors are managed to improve repeatability.

• How the interferometer and optics are arranged to measure wavelength with sub-ppm accuracy
• Methods for counting interference fringes and handling phase uncertainty
• Techniques for aligning reference and unknown laser beams to minimize errors
• Historical context of improving wavemeter designs and achieving higher stability

Ideal for engineers and technicians working with optical fiber communications, laser wavelength measurement, and precision metrology.
