Laser Locking Electronics

Intelligent solution for versatile laser locking

TOPTICA provides exceptionally stable tunable diode lasers that feature narrow linewidths. Still, many demanding applications have even more rigorous requirements. To reduce remaining frequency fluctuations or cancel out long-term frequency drifts, active frequency stabilization, or "locking", is required.
