LWA-1k-1550

High Resolution Frequency Noise Analyzer & Controller

The HighFinesse LWA-1k-1550 model of the Linewidth Analyzer series is the ultimate high-end device for measuring, analyzing and controlling frequency and intensity noise of lasers. The superb sensitivity of the LWA-1k-1550 is achieved by combining an interferometric working principle with high-end optical and electronic components.
 
The main features are:
  • Frequency noise, spectral lineshape and relative intensity noise(RIN) analysis
  • Intrinsic linewidth measurement range down to 500 Hz
  • Combined linewidth measurement range down to 2 kHz
  • Frequency noise spectrum sensitivity of 10 Hz/√Hz with a dynamic range of 50 dB between 10 Hz and 2 MHz
  • RIN down to -150 dB/√Hz
  • Extremely robust against acoustic noise
  • Error signal generator for further linewidth, frequency noise or RIN reduction
