Bristol 772 Series Pulsed Laser Spectrum Analyser

The 772B-MIR Laser Spectrum Analyser from Bristol Instruments combines proven Michelson interferometer technology with fast Fourier transform analysis to characterise the spectral properties of lasers that operate from 1 to 12 µm. When used with CW lasers, the model 772B-MIR operates and performs just like Bristol's 771B-MIR Laser Spectrum Analyzer. What makes this system so unique is that it employs a sophisticated algorithm to enable the measurement of pulsed lasers that have a repetition rate as low as 50Hz.

Features:

• Spectral resolution of 4GHz

• Operation from 1 to 12 µm

• Wavelength accuracy of +/- 10 ppm

• Optical rejection ratio as high as 20dB

• Free-space aperture input with visible alignment aid

• Straightforward operation with a PC using USB or Ethernet

• Display software provided to control measurement parameters, display spectra, and report wavelength data

• 5 year warranty

The 772B-MIR Laser Spectrum Analyser has a spectral resolution of 4 GHz and wavelength accuracy of ± 10 parts per million (± 0.08 nm at 8 µm). An optical rejection ratio of about 15 - 20 dB is achieved assuming a sufficient number of laser pulses (> 30,000) are used to generate the interferogram.
