BURLEIGH WA-7000 Multi-line Wavemeter

The Burleigh WA-7000 Multi-line Wavemeter is an instrument designed for automatic and accurate wavelength measurments of countinuous wave (CW) laser sources. The interference fringes produced by the input laser radiation in the scanning Michelson interferometer are sampled in the interferometer scan at equally spaced intervals calibrated by a built-in reference laser. A high-speed digital signal processor computes a Fourier Transform of the interferogram to obtain a spectrum of the input laser that is displayed on the Wavemeter screen. Discrete wavelengths included in the input laser source appear as peaks in the spectrum. The wavelength of each peak is accurately determined based on the knowledge of the reference laser wavelength. The WA-7000 Multi-line Wavemeter uses a HeNe reference laser that provides an absolute wavelength accuracy better than ±1 part per million. Inside the instrument, both the reference laser and the input laser beams are coupled into the monolithic interferometer by fiber optic cables that ensure good optical alignment. An embedded computer generates the spectral display and derives the wavelength and power of each spectral peak. The front panel display, and other input and output functions are also controlled by the computer. The Wavemeter front panel has buttons to select different display screens, change parameters or display attributes, and manipulate the collection of data.

*This is a Web introductory price for one calibration of the BURLEIGH WA-7000. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.


Related Optical Terms and Definitions. For a complete list go to our  Terms and Definitions Page.

Chirp
A change in the optical frequency caused by direct modulation of the laser. A chirp is a signal in which the frequency increases ('up-chirp') or decreases ('down-chirp') with time. In some sources, the term chirp is used interchangeably with sweep signal.

Isolation
The extent to which optical power from one signal path is prevented from reaching another signal path.

Polarization Extinction Ratio
Polarization Extinction Ratio is the ratio of optical power in the slow axis of the polarization maintaining fiber to optical power in the fast axis within a specified wavelength range.

Sidemode Suppression Ratio
Sidemode Suppression Ratio is the ratio of average signal power to the optical power of the highest sidemode within a distance from 0.1 to 6 GHz to the signal’s optical frequency, expressed in dB.

Wavelength Stability
Wavelength Stability is the change of wavelength during given time span, expressed as ± half the span between the maximum and the minimum of all actual wavelengths.
