DFC Difference frequency comb

Frequency combs are the robust and reliable backbone of cutting-edge experiments. This thought is guiding our frequency comb product development. It’s the shared vision with our customers, who want to focus more on the application and spend less time maintaining their system.

TOPTICA's DFC CORE + was designed to combine highest stability with reliability at the push of a button. With our award-winning CERO technology we achieve ultra-low noise performance while reducing complexity: The light waveform itself is fixed from pulse to pulse, by passively setting the carrier-envelope offset frequency f_CEO to zero. No control loops, no electronic noise and orders of magnitude faster noise suppression compared to conventional frequency combs.

With our complete frequency comb solutions, including seamless locking of all TOPTICA lasers, we don't deliver separate components but stable optical frequencies from the UV to the mid-IR. By that, even the most demanding applications like optical clock comparison and sub-Hz spectral purity transfer are enabled - reliable and easy to use.

Applications

Optical quantum clocks

Welcome to the next generation of time and frequency metrology. Harnessing the full power of quantum physics and ultra-stable lasers, optical quantum clocks are redefining how we measure time...

Atom laser cooling & trapping

Over the last century, many experiments and theoretical studies on matter waves and the interaction between light and atoms have paved the way to modern atom optics and its application in research & industry.

Quantum computing & simulation

Lasers are used to realize most of the quantum systems used for quantum computing and simulation. Lasers are utilized to prepare quantum states, to realize quantum gates, and to read out qubits. In addition, lasers are used to link different quantum systems (e.g. to connect quantum computers or quantum computing subunits), a major task of quantum communication. Tunable diode lasers, fiber amplifiers, optical frequency combs, and wavelength meters, ideally combined in laser rack systems as complete solutions, are the most important products.

6G & communication research

As data demands grow toward transfer rates of several hundred gigabits per second, wireless communication research is moving towards higher carrier frequencies - reaching into the terahertz range to achieve higher bandwidths. TOPTICA’s TeraScan systems provide an ideal testbed for this research, offering tunable continuous-wave THz emission from 50 GHz to 1.2 THz. This enables the precise characterization of communication components and transmittance channels.

Quantum dots & microcavaties

Highest stability and absolute frequency accuracy for inspecting PICs, semicon and RF devices. Expandable to high scan speed and broadest coverage.

Quantum communication

Quantum communication is redefining how information is transmitted, secured, and trusted. At the heart of this technological revolution are high-performance laser systems that generate, control, and stabilize light at the quantum level.
