Application Example
Sub-Doppler Spectroscopy

Absorption / a.u.

High resolution spectroscopy requires laser features like narrow linewidth, highpassive stability, exact adjustable wavelength as well as an excellent fine tuningability. The figure summarizes experimental data which have been determined withour Littrow laser system. The blue trace shows an absorption trace of theD2-line of Rubidium. More demanding is the Doppler-free detection of the Lambdips (c/f W. Demtröder, LaserSpectroscopy, Springer 1998). The red trace shows
the doppler-free measurement of the Lamb-dip of the D2-line of Rubidium.

Application Example
Water Vapor Spectroscopy
Water vapor show various absorption bands. Typical wavelength for spectroscopy
of water vapor are 935nm or 1410nm. The figure summarizes experimental data
which have been determined with our Littman/Metcalf laser system in the 1410nm
wavelength range. The trace shows an absorption signal of an optical water vapor
concentration measurement in ambient air. The total tuning range is 1nm with1388nm as center wavelength of the scan.

Application Example
External Cavity Diode Laser
The principle application of our PilotPZ laser controller are diode lasers with an
external cavity. Typical laser configurations are Littrow- and Littman/Metcalf-cavity.
We offer special plug-in modules for most measurement applications which areneeded for state of the art measurements in spectroscopy such as trace gas
analysis as well as for metrology. Please check our web-page for details.
