Laser lineshape spectrum
The HighFinesse Linewidth Analyzers (LWAs) are very versatile, robust and compact instruments for measuring, analyzing and controlling frequency and intensity noise of lasers. This makes them ideal equipment for exact laser characterization in real time.
The superb sensitivity is achieved by combining an interferometric working principle with high-end optical and electronic components. Based on the measurement of frequency deviations over time calculations are possible of the frequency noise density spectrum, the optical lineshape with evaluation of intrinsic (Lorentzian) linewidth down to 350 Hz and effective (optical) linewidth, and the relative intensity noise (RIN). By further analysis many additional quantities are accessible. The unbiased measurement principle of the LWA is superior to optical delay line techniques, because the latter rely on non-trivial evaluation needs due to the technique inherent loss of information. The LWA also allows for linewidth reduction of lasers using PID control.
The LWA-1k product series offers instruments for the measurement down to very low linewidths. The LWA-100k products series enables accurate linewidth measurements over a very large wavelength range- 产品优势
