Fizeau Wavemeter (FZW)

 Michael Iluz

Key Features:

  • Operates over 400 – 1100nm without recalibration
  • 3-sigma uncertainty of 600MHz; typical measurement accuracy < 200MHz
  • Built-in PID for laser frequency stabilisation
  • Runs from USB or DC jack, no computer required!
  • Simple computer interface over Ethernet/USB

Description

A compact wavelength measurement device based on Fizeau interferometers, providing reliably accurate measurements over a wide range of wavelengths (400-1100nm) without recalibration. The measurement and calculation is performed on the device, with the result displayed on the screen, removing the need for a host computer. Turn it on, and know your wavelength in less than 2 seconds.

The small form factor makes it an easy-to-use analysis tool, and can be powered either through USB or from a DC plugpack. It provides an analogue output for either wavelength monitoring or laser stabilisation via a built-in tuneable PID controller.

It includes both Ethernet and USB interfaces for command and query, with immediate integration into existing control systems (LabVIEW, MATLAB and python drivers provided). It comes with a fully-featured software suite, including long-term measurement and modehop-free scan-range measurement. A simple one-button recalibration procedure using an external reference source compensates for any long-term drift.

Matching fibre switches are available (see below), able to measure and stabilise up to 8 separate lasers.
