Where to Buy Linewidth Measurement Equipment

HighFinesse linewidth analyzers are the ultimate high-end instruments for measuring, analyzing and controlling frequency, linewidth and intensity noise of laser light sources. The product series covers a measurement range from 450 nm up to 1625 nm and enables the analysis of both very narrow laser lines down to 1 kHz as well as broader spectra up to 100 MHz. Thanks to the included software, the instrument delivers real-time analysis, with no need for further calculation. The analyzers feature an extremely high resolution and accuracy and are ideal for optimizing the stability of laser setups.

Quantifi Photonics designs and manufactures a wide range photonic test solutions including lasers, optical spectrum analyzers, power meters and more. The company specialize in testing silicon photonics, co-packaged optics (CPO) and pluggable transceivers. Their solutions are used to test photonic integrated circuits (PICs), optical engines and pluggable optical transceivers, and are optimized for high density, high channel count applications in manufacturing environments. The company also offers unique solutions for coherent optical communications, photon Doppler velocimetry, and optical pulse analysis.

All of TOPTICA’s tunable diode lasers offer a narrow linewidth of typically 100 kHz, corresponding to coherence lengths of almost 1 km. By stabilizing these lasers even further with TOPTICA’s locking electronics, linewidths below 1 Hz are possible.
