LaseLock
LaseLock is a universal and compact laser stabilization electronics (lock-box) that allows to stabilize tunable lasers (e.g. diode lasers, Ti:Sapphire or dye lasers) in their frequency. For this, particularly optical resonators (Fabry-Perot cavities) and atomic absorption or fluorescence lines are serving as references. Vice versa, also optical resonators can be stabilized towards a given laser frequency by means of mechanical actuators (e.g. piezo actuators).
side-of-fringe stabilization
top-of-fringe stabilization
(stabilization to maximum (or minimum), 'lock-in'-technique)
Principle
The LaseLock conveniently combines the following components in a compact and user-friendly box:
• Input amplifiers (incl. generation of difference and/or normalisation signal)
• Sine generator
• Phase-synchronous detection
• PID regulator
• Scan generator
• Output amplifier

Application Example
Supplier
The TEM Messtechnik GmbH is an innovative medium-sized company in Hannover. It was established in 1988 and changed to a GmbH (Ldt.) in 1998. TEM is specialized in converting scientific results and ideas into real-world applications. The development process goes from the first idea to the production-ready solution and includes customer specific adaption of the standard products, new development at the electronic devices, analog and digital solutions, OEM-boards, modular systems or stand-alone devices.
