LaseLock is a universal and compact laser frequency stabilization electronics (“lock-box”), which can be used to frequency stabilize lasers (such as diode lasers, Ti:sapphire or dye lasers).
Stabilized lasers are sought-after components for many applications. By using LaseLock, laser drift can be almost completely eliminated and very narrow line widths can be generated with extreme stability. LaseLock measures and detects frequency changes of the laser and provides corresponding feedback signals so that these changes can be corrected and stabilized.
In particular, optical resonators or atomic absorption or fluorescence lines serve as frequency references. These reference components are also available from TEM Messtechnik:
- CoSy → offers reference standards based on saturation spectroscopy, with cesium, rubidium or potassium cells available
- iScan → is an active Fabry Perot interferometer, which can provide a stabilization signal at any frequency (“active frequency correction”)
Conversely, it is possible to control optical resonators to a given laser frequency using mechanical actuators. The drivers required for this are optionally available for LaseLock (HV-driver for piezo actuators, HC-driver for galvos or DLD-driver for diode lasers, incl. temperature and current control).
