771 Series Laser Spectrum Analyzer

Bristol Instruments Inc.Request Info
Bristol  Instruments 771 Series Laser Spectrum AnalyzerThe 771 Laser Spectrum Analyzer combines proven Michelson interferometer technology with fast Fourier transform analysis to measure both a laser’s wavelength and spectrum. Absolute wavelength is determined to an accuracy as high as ± 0.2 parts per million. And, with a spectral resolution as high as 2 GHz and an optical rejection ratio (ORR) of > 40 dB, the system provides the most detailed information about a laser's spectral properties.

Two versions of the 771 Laser Spectrum Analyzer are available. The model 771A is the most precise, measuring wavelength to an accuracy of ± 0.2 parts per million (± 0.0002 nm at 1000 nm). For experiments that are less exacting, the model 771B is a lower-priced alternative with an accuracy of ± 0.75 parts per million (± 0.0008 nm at 1000 nm). These specifications are guaranteed with a built-in HeNe laser wavelength standard, thereby ensuring the most meaningful experimental results.

The 771 Laser Spectrum Analyzer is available in four broad wavelength configurations to satisfy virtually any experimental requirement. These ranges are the VIS (375 – 1100 nm), NIR (520 – 1700 nm), IR (1 – 5 µm), and MIR (1.5 – 12 µm). The 771 system operates with CW lasers, and a special measurement algorithm enables operation with pulsed lasers that have a repetition rate greater than 50 kHz and a pulse length of more than 50 ns.

The laser under test enters the VIS and NIR versions of the 771 Laser Spectrum Analyzer through a pre-aligned fiber-optic input to ensure optimum alignment. Since fiber is not readily available for infrared wavelengths, the laser under test enters the IR and MIR systems through a free-space aperture, through which the internal HeNe reference laser is emitted as a visible tracer beam to facilitate alignment. The 771 system operates with a PC running under Windows, via USB or Ethernet interface. Software is provided for two modes of operation. The Spectrum Analyzer mode is used to generate the spectrum of a laser, displayed in a graph with the wavelength axis calibrated to the specified accuracy of the instrument. The Wavelength Meter mode is used to accurately measure absolute laser wavelength.
