Resulting in a linewidth reduction of the laser. Ideally combined with an ECDL or DFB laser. 

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.

Explore how TOPTICA’s laser systems enable cooling and trapping of charged ions — the backbone of today’s quantum-precision experiments.

Creating Bose-Einstein condensates and degenerate Fermi gases requires sophisticated laser cooling and trapping capabilities. Our integrated laser solutions support the multi-stage cooling processes necessary for reaching ultracold temperatures where quantum effects dominate, enabling exploration of exotic quantum phases and many-body physics.

Rydberg atoms with their enhanced interactions open new possibilities in quantum simulation and quantum information processing. Our high-power, narrow-linewidth laser systems enable efficient excitation to Rydberg states, supporting dipole blockade experiments and the development of Rydberg-based quantum gates.

Electromagnetically induced transparency (EIT) and optical pumping experiments demand precise control over atomic population states. Our tunable laser systems provide the spectral purity and intensity control needed for coherent population manipulation, supporting applications from quantum memory to slow light experiments.

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...

Just often we don't realize it in normal life. This is because quantum systems are usually too tiny and are often destroyed in their key properties or their quantum-ness by even subtlest changes in the environment.

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.

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 addtion, lasers are used to link different quantum systems (e.g. to connect quantum computers or quantum computing sububits), 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.
