Did you know that Helium was discovered in space before it was spotted on earth? By analyzing the emission spectrum of the sun, a new element was showing up in the second half of the 19th century. It was named Helium, referring to the Greek name for the sun.
Since then spectroscopy became a fundamental tool in many fields in science and industry. Spectroscopy allows to detect, identify and quantify the status of various atoms and molecules because of their unique spectra.
Nowadays lasers are one of the most important tools in spectroscopy. Single frequency lasers can act as a stable spectral reference and their small linewidth allows to address specific atomic transitions. For example, our portfolio comprises lasers aiming at the strong absorption lines of water at 935 nm.
We use different technical approaches to realize the single frequency lasers. In case of this application we have chosen a DFB laser with monolithically integrated grating.
