Lasers for science and industry that meet the highest standards of our customers. We develop and manufacture narrow linewidth lasers to scale quantum computing, femtosecond lasers for extra bright microscopy images, and reliable lasers for semiconductor inspection and industrial metrology.
All Wavelengths
With 190 nm to 0.1 THz we cover the widest wavelength spectrum on the market. This is part of our mindset. But we also embrace all wavelengths of creativity and humor that make TOPTICA, well… TOPTICA.

QUANTUM TECHNOLOGIES
Long coherence time for high qubit fidelity
Our ultra-stable clock laser systems are an important part of our solutions for quantum 2.0 applications. Their linewidth is reduced to less than 1 Hz via frequency stabilization, ideal for working with narrow atomic transitions in quantum computing. With industrial-grade quality and 19” rack integration option it's the scalable choice for driving up the qubit count.

Brighter images for two-photon microscopy
In two-photon microscopy, peak-power is brightness! Our femtosecond lasers provide short pulses, high power, and most importantly a clean temporal pulse shape. The fiber coupling is a game-changer for simplifying multi-photon microscopy. No mirror alignment, no power meter, just automated fiber coupling.

The next generation lasers for semicon is reliable, small and has a low cost of ownership. No more bulky and power hungry gas lasers. Our all diode or fiber approach makes us the ideal partner for driving future innovations in the cutting-edge fields of optical inspection (e.g. brightfield and darkfield microscopy) and metrology techniques (e.g. ellipsometry or scatterometry).
Proven by Experts
The company, now named TOPTICA, has grown and thrived over 30 years to become the undisputed world market leader in scientific diode lasers.
Theodor W. Hänsch, Nobel Lauretate in Physics (2005), Max Planck Institute of Quantum Optics, Germany
Our DFC system has been running reliably for more than 8 years now and only needed two minor realignments. After our lab's relocation TOPTICA supported us with offering a maintenance service.
Dr. Caroline Champenois, Research director and group leader
CNRS, Aix-Marseille University, France
It was TOPTICA's characteristically pleasant collaborative style that was essential for the success of our project.

TOPTICA Launches TeraScan ultra: Redefining Terahertz Precision with 1 Hz Spectral Resolution
TOPTICA Photonics, a global leader in precision laser systems, proudly announces the launch of the TeraScan ultra – an ultra-high-precision continuous-wave (cw) terahertz platform featuring comb-locked stability and unmatched spectral resolution down to 1 Hz.
The TeraScan ultra is designed to meet the most demanding requirements in THz communications research, channel sounding, wafer inspection, and high-resolution spectroscopy. With a bandwidth of up to 5 THz and ultra-low phase noise, it sets a new benchmark in the generation and control of tunable terahertz radiation.
At the heart of the system are two diode lasers – one tunable, one fixed – both locked to a single optical frequency comb. A photomixer emitter converts the optical beat signal into a tunable, monochromatic THz wave. TOPTICA’s proprietary “endless frequency shifter” ensures seamless frequency tuning while maintaining absolute control over phase and frequency – a crucial requirement for applications like photonic vector network analysis.
The system uses state-of-the-art InGaAs photomixers: a photodiode emitter and a Rh:InGaAs photomixer receiver, both packaged into compact, fiber-coupled modules. Operation modes include fixed frequency, sweep, and triggered step scan – fully software-controlled.
TOPTICA’s TeraScan ultra is ideal for researchers who demand ultimate frequency stability, scanning flexibility, and sub-Hz phase coherence across the full terahertz spectrum.
