Precision Unlocked: Covesion Launches Frequency-Stabilised Laser System for Quantum Innovation

Covesion is excited to announce the launch of its Locked Laser System,  a turnkey solution built on our established fibre-coupled MgO:PPLN waveguide technology. Designed to support rubidium (Rb) atom applications, including quantum computing, sensing, and timing, the system delivers a highly stable, narrow-linewidth laser output at 780 nm, frequency-locked via an integrated Rb spectroscopic cell.

The Locked Laser System automatically provides a locked, offset frequency output, enabling users to define the frequency offset relative to the absolute reference. This ensures a spectrally pure, stable output ideal for precision applications. A DC seed offset is employed to maintain lock, offering a stronger lock and improved spectral quality. Importantly, the output beam is not part of the locking process, helping to maintain its optical purity during operation.

The system is also designed with flexibility in mind, offering a customisable platform suitable for a range of setups and end uses. An optional fast modulation feature is available, supporting experiments or systems that require rapid output variation.

Locked laser system key features:

• Turnkey system with locked, offset frequency output
• Based on Covesion’s fibre-coupled MgO:PPLN waveguide technology
• Rb spectroscopic cell provides absolute frequency reference
• Output beam excluded from the locking loop
• DC seed offset enhances lock strength and spectral purity
• User-selectable frequency offset from reference
• Optional fast output modulation
• Targeted for Rb-based quantum applications

Complementing our expanding range of photonic solutions for precision R&D and OEM deployment, the Locked Laser System is available to order now and is featured in the latest version of our product catalogue.
