Digitally controlled, fast laser locking module

Quantity

Key Highlights

  • High-performance laser frequency stabilization
  • Enables laser linewidths <1 Hz when locked to a stable reference
  • Ultra-fast feedback with <10 ns delay
  • High-bandwidth noise suppression up to 50 MHz (-3 dB)
  • 6-parameter PI³D² fast regulator
  • Digital control with convenient remote operation
  • Fully integrated with the DLC pro platform
  • Supports PDH locking and frequency-comb locking
  • Suitable for phase locking between two lasers
  • Designed for ultra-narrow linewidth and high-coherence applications

Description

TOPTICA's FALC pro locking module is not compromising. It's fast and convenient. A high-speed regulator is at its heart and allows it to address even the most demanding applications, including laser driving ultra-narrow transitions utilized in optical clocks (clock transitions) or quantum computers (optical qubits). This regulator is combined with a convenient user interface, TOPTICA’s generic DLC pro interface, which allows you to optimize the feedback parameters with ease. The digital control interface of the analog regulator also enables full remote operation.
Typical applications of these locking modules include linewidth narrowing of a laser using external reference cavities, e.g., in Pound-Drever-Hall locks (in combination with PDH/DLC pro), locking any DLC pro-controlled TDLS laser to a frequency comb, or phase locking one TDLS laser to another.
The combination of the FALC pro with the DLC pro Lock increases the convenience even more because Click & Lock as well as ReLock mechanisms are easy to setup.
The FALC pro not only promises the best performance but also a lot of fun in setting up the feedback to reach the narrowest linewidths, the lowest phase noise, the longest coherence times, … or just a very good high-speed lock.
