Laser Frequency Stabilisation LaseLock

LaseLock is a universal and compact laser stabilisation electronics (lock-box) that allows to stabilize tunable lasers (like 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).

Two different methods can be applied:
1         side-of-fringe stabilization
2        top-of-fringe stabilization (stabilization to maximum (or minimum), ‘lock-in’-technique)

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

Stabilisation of the frequency of an external cavity diode laser to an atomic absorption line
