From tunable single-frequency lasers to broadband mid-infrared sources and ultra-stable frequency combs, TOPTICA’s innovations offer powerful tools for scientists and engineers working at the forefront of optical research. Some of their products are listed below:

DFB pro BFY: High-Stability Single-Frequency Laser for Sensing and Spectroscopy

The DFB pro BFY is a distributed feedback laser that provides narrow-linewidth, single-mode emission across the near-infrared spectrum from 1064 nm to 2000 nm. This laser supports mode-hop-free tuning, which allows seamless frequency sweeps required in gas detection, molecular spectroscopy, and phase-sensitive interferometry.

Designed with an integrated optical isolator and high polarization extinction ratio, the laser ensures pure linear polarization, making it ideal for applications that demand polarization-sensitive detection. The combination of thermal and electronic tuning mechanisms allows both coarse and fine wavelength control without mechanical adjustments. The Ethernet interface enables easy remote operation, while the robust butterfly package supports stable integration into laboratory and industrial setups.

FemtoFiber dichro midIR: Broadband Mid-Infrared Source for Molecular Fingerprint Detection

The FemtoFiber dichro midIR delivers supercontinuum light in the 5 µm to 15 µm range, covering key absorption features used in mid-infrared spectroscopy and hyperspectral imaging. This spectral coverage enables detailed identification of organic and inorganic compounds, making it ideal for chemical analysis, environmental sensing, and biomedical research.

With a user-friendly turnkey design, the source combines mode-locked fiber technology and automated difference frequency generation to provide hands-free, alignment-free operation. The high output power and fast repetition rate ensure consistent data acquisition in high-throughput imaging and spectroscopy experiments. Controlled via USB and Ethernet, the system is easy to set up and operate in both research and industrial environments.

LD-1550-0100-DFB-1: Compact DFB Laser Diode for Resonant Spectroscopy and Optical Sensing

The LD-1550-0100-DFB-1 is a distributed feedback laser diode centered at 1550 nm, offering temperature-stabilized single-mode output with a narrow linewidth. It includes an integrated thermoelectric cooler and thermistor, enabling excellent wavelength stability and efficient thermal management.

Its design supports fast modulation and electric tuning, making it suitable for applications such as high-resolution spectroscopy, fiber sensing, and resonance locking. With its butterfly package and fiber-coupled output, this laser diode is ideal for compact OEM designs and research systems requiring consistent, mode-hop free operation.

DFC CORE +: Ultra-Stable Optical Frequency Comb for High-Precision Metrology

The DFC CORE + is a cutting-edge optical frequency comb that offers reliable, phase-coherent emission at a central wavelength of 1560 nm, with extensions covering a range from 420 nm to 2000 nm. It achieves sub-Hertz linewidth and timing stability down to the 10 to the power of minus eighteen level, making it a preferred solution for frequency metrology and optical clock development.

Using TOPTICA’s patented CERO technology, the comb provides multiple fiber-coupled outputs and can be fully controlled via Windows-based software. With extremely low phase noise and high stability across time scales, the system is ideal for dual-comb spectroscopy, laser referencing, quantum system calibration, and advanced timing distribution in laboratory and field applications.
