While the width of the spectral feature in atomic spectroscopy is ultimately limited by the natural linewidth of the specific transition, the spectral feature of a Fabry-Pérot cavity is given by the…
The most straightforward way to generate an error signal is to send part of the laser light through the cavity and measure the transmission with a photodiode behind the cavity. Analogous to the…
With more than 15 years of experience in femtosecond fiber laser technology and fiber laser design, TOPTICA offers innovative and custom-tailored laser systems that enable cutting-edge research in…
The PD signal is a function of the phase difference between the laser light and the optical reference under consideration. This signal is only constant if the frequency difference between the laser…
TOPTICA solution
With the CoSy, TOPTICA offers a plug-and-play spectroscopy package which is based on Doppler free saturation spectroscopy. It includes the gas cell as a reference together with the…
