TOPTICA’s CLS Ultra-Stable Clock Laser for Real-World Quantum Applications: Delivers 10⁻¹⁵-level frequency stability in a robust, deployable system

TOPTICA Photonics is strengthening its position in ultra-stable laser technology with its Clock Laser System (CLS), designed to deliver reliable and ultra-low phase noise optical frequency references for quantum technologies, precision metrology, and advanced sensing.
TOPTICA: Record-Purity Microwaves. Now Commercial: TOPTICA Brings Ultra-Pure Photonic Microwave Technology from Lab to Industry

TOPTICA Photonics announces the launch of its X-band Metrological Microwave Solution (X-MMS), a commercially available ultra-low-noise microwave source that ranks among the purest signals achieved worldwide. Developed using photonic technology, the system transfers the stability of an optical reference into the microwave domain, enabling unprecedented signal purity and stability in an industrial-grade platform.
TOPTICA Frequency Combs: Complete DFC Systems offer a stable, optical frequency from a single laser system

Complete stabilized laser systems including the DFC CORE +, any desired wavelength extension, beat units, stabilization electronics, wavelength meters, counters, and lasers are now available from one source.
TOPTICA Photonics: Rock Solid – Zero Offset Frequency Combs

At TOPTICA, we believe a frequency comb should be stable and reliable in every situation.

Frequency combs are the robust and reliable backbone of an experiment. This thought has guided our frequency comb product development. It’s the shared vision with our customers, who want to focus more on the actual research and spend less time maintaining their system.
Toptica DFC CORE + Compact high-performance frequency comb

The Toptica DFC CORE + is a robust, 19 inch compatible optical frequency comb based on Erbium fiber technology. It is the core system for applications like optical clocks, micro wave generation or phase-locking of cw-lasers and can be equipped with additional wavelength extension s and options. Its unique fCEO-stabilization is based on Difference Frequency Generation (DFG) and comes with many advantages such as high robustness and ultra-low phase noise.
Toptica DFC Wavelength Extensions Wavelength conversion from 1560 nm to 420 - 2000 nm

Various extension modules are available that convert the offset-free fundamental output of the DFC CORE + from 1560 nm to any desired wavelength between 420 nm and 2000 nm. The wavelength conversion in these modules is achieved with the well-established technology of TOPTICA’s ultrafast fiber lasers.
Toptica DFC BC / DFC BCF / DFC MD Flexible beat detection units

TOPTICA's beat detection consists of two flexible modules: DFC BC (or DFC BCF) and DFC MD. Separating beam combination and beat detection into two units allows for placing them at different locations.
Toptica Locking Electronics: FALC & PFD Push-button phase-frequency lock

The DFC locking electronics consisting of the Phase Frequency Detector (PFD) and FALC 110 provides high-end phase frequency locking for comb applications.
Toptica Difference Frequency Comb (DFC): Compact, robust, high-end and convenient

TOPTICA’s frequency comb product line uses their proprietary CERO-technology which is based on Difference Frequency Generation (DFG). It is inherently f_CEO-stable and combines high robustness, high-end performance and a convenient user-interface in a compact format.
Toptica DFC SEED Low-noise OPCPA seeder

The DFC SEED unit is dedicated for OPCPA and high power amplifier seeding that require phase-stable ultrashort laser pulses at 1560 nm and 1030 nm or 1950 nm. It combines an outstanding passive CEP stability which challenges the best Ti:sapph lasers with the convenience and robustness of a fiber laser. Long-term drifts of the CEP that are caused by a subsequent amplifier chain can be compensated through a dedicated feedback channel. The repetition rate frep of the DFC SEED can be synchronized to any appropriate reference.
