PhaseLock is a system to control the pulse timing of pulsed lasers. It controls the repetition rate of pulsed lasers and adjusts this rate in a way that the pulses are generated with at fixed times relative to a reference clock.

• Compact, stand-alone locking electronics for pulsed lasers
• pulse timing stabilization
• 2 independent PID regulators
• High-voltage output for piezo actuators
• Lock point validity detection and automatic “search” function
• Multi-channel monitor for display of regulator signals

PhaseLock combines all components needed for phase stabilization in a userfriendlycompact device:

• Fast input amplifiers
• Phase comparator
• 2 independent PID regulators, adapted especially to resonant systems like piezo-driven optical components
• Scan generator, for adjustment or supervision of the physical system
• Output amplifier, user-selectable as high-voltage amplifier for piezo actuators, or as low-voltage amplifier generating a control signal for external amplifier sections
• Logic section for automatic recognition of successful locking
