Linewidth Analyzer
Highfinesse’s Linewidth Analyzer or (LWA) provides high-resolution measurement and analysis of the spectral shape of single-frequency lasers. It also allows measurement of the frequency noise spectrum of the laser. A combination of two interferometric measurement modes allows the LWA to quickly acquire laser source information.
It comes in two versions:
High Resolution Frequency Noise Analyzer & Controller LWA-1k-1550
- Telecom version at 1.55um
- Frequency noise, spectral shape and noise intensity (RIN) analysis
- Intrinsic spectral width measurement up to 500 Hz
- Frequency noise sensitivity of 10 Hz / Hz with a dynamic range of 50 dB between 10 Hz and 2 MHz
- RIN up to -150 dB / Hz
- Very robust against acoustic noise
- Error generator for INR reduction, spectral width and frequency noise
High Resolution Lineshape Analyzer LWA-100k
- Visible domain and near IR
- Spectral shape analysis and frequency noise
- Intrasque spectral width measurement 20kHz-1MHz
- Combined measurement 100kHz-300MHz
- Frequency noise sensitivity <100 Hz / Hz for frequencies above 100 kHz
- High speed of acquisition 30 MSa / s
- Precision 20 kHz
