EXFO introduces pulsed wavemeter system

30 May 2003 Quebec City, Canada Lightwave -- EXFO Electro-Optical Engineering Inc. has introduced the WA-4550 Pulsed Wavemeter laser wavelength meter. The new WA-4550 displays accurate, continuous, real-time wavelength measurements without interrupting the experiment in progress, according to the company. The WA-4550 eliminates the need to rely on the laser manufacturer's calibration data to verify wavelength.

30 May 2003 Quebec City, Canada Lightwave -- EXFO Electro-Optical Engineering Inc. has introduced the WA-4550 Pulsed Wavemeter laser wavelength meter. The new WA-4550 displays accurate, continuous, real-time wavelength measurements without interrupting the experiment in progress, according to the company. The WA-4550 eliminates the need to rely on the laser manufacturer's calibration data to verify wavelength.

Development was driven by customer requests for a high-accuracy means of confirming the exact wavelength of a pulsed laser. It simplifies what can be a frustrating, time-consuming process. Significant benefits include:


  • High-accuracy, continuous wavelength measurement to ± 0.02 cm-1
  • Continuous calibration with built-in wavelength standard
  • Wide range of operation from 400 to 1100 nm
  • Simple system setup with USB interface eliminates communications complications.

The WA-4550 goes beyond simple calibration by providing continuous readings during data collection. These wavelength readings can be displayed in real time or stored for later analysis, providing additional insight into the meaning of collected experimental data.

"The new WA-4550 Pulsed Wavemeter system truly is a case of 'back by popular demand,'" said David Farrell, president of EXFO Burleigh Products Group Inc., a wholly owned subsidiary of EXFO. "We've gotten numerous requests from customers to bring back our pulsed wavemeter system. We've updated the software, mechanics, and specifications, so we can once again say there simply is no better way to confirm the exact wavelength of a pulsed laser than with the EXFO Pulsed Wavemeter."
