Options
External Trigger (TTL)
External triggering via TTL guarantees synchronization between pulsed excitation and measurement. It provides low-noise signals without parasitic parts when measuring pulsed signals with low duty cycles.
Laser Control (PID)
With the PID option it is possible to stabilize the frequency of a laser connected to the wavelength meter using a software based proportional-integral-derivative controller (PID controller). Unlike analog PID electronics, the PID option provides software based signal processing, allowing the laser to be stabilized to a specific user defined frequency or regulated with an arbitrary pattern. This makes it extremely useful in experiments where the laser frequency has to be actively regulated or varied to fit changing experimental conditions, such as laser cooling, atomic detection, trapping and spectroscopy.
Linewidth Estimation (L)
The linewidth estimation of a singlemode laser source is performed by a special algorithm which eliminates the interferometer’s instrument response function. The algorithm enables the estimation of the linewidth with an accuracy better than the tenth of the instrument FSR. The linewidth option can also be used for measuring the linewidth of multimode lasers or lasers with sidebands. In this case, the longitudinal mode splitting needs to be less than the instruments spectral resolution and the calculated result is the FWHM of the envelope function of the multiline spectrum. Any instrument can be upgraded with the L-option. Singlemode fibers are required.
External Calibration (CAL)
The wavelength meter WS6-600 IR-I standalone features autocalibration via an integrated calibration source. This guarantees the accuracy and stability of measurements with our wavelength meter. For higher accuracy in the range from to we offer the SLR 1532.
