Key Markets

  • Quantum Optics & Spectroscopy

    Users benefit from TOPTICA’s tunable diode lasers because of reliability, precision, narrow linewidth, as well as tunable laser frequency, or active frequency stabilization. The systems are typically used for demanding applications like laser cooling, trapping, and manipulation of atoms or ions in quantum optics, spectroscopy, or interferometry. TOPTICA is renowned for the widest wavelength coverage of tunable diode lasers on the market, providing high-power lasers even at exotic wavelengths.

  • Biophotonics & Microscopy

    Lasers play an invaluable role in instrumentation for life sciences and medical applications. In fields such as microscopy, flow cytometry, or in medical and pharmaceutical instruments, TOPTICA lasers fulfill the demand for modern photonic sources. TOPTICA’s portfolio includes UV, VIS and NIR laser sources, flexible multi-laser engines and pulsed fiber lasers for time-resolved applications.

  • Test & Measurement

    With great expertise in optical and electronic control of lasers, TOPTICA provides lasers of lowest noise at highest wavelength stability. They are the perfect instruments for high-precision measurements of semiconductors, optical components, distances or chemical compositions. Frequencies in the terahertz region (0.1 THz to 6 THz)  become accessible with TOPTICA’s integrated solutions, opening up a wealth of novel applications in applied science, non-destructive testing and industrial process control.

Key Technologies

  • Single Mode Diode Lasers

    TOPTICA’s single-mode diode lasers set new standards in terms of power, low noise and convenient OEM integration. They come with diffraction limited TEM00 output and reliable spectral properties, as well as optional robust fiber coupling. Compact design and low power consumption make them superior to old-fashioned, bulky and inefficient gas lasers. Multi laser engines seamlessly integrate several wavelengths into true one-box laser systems – switching between colors has never been easier. The systems‘ flexibility and ease of use enable straightforward deep integration into any customer’s system design.

  • Tunable Diode Lasers

    Narrow linewidth, highest accuracy and great ease of use are the key attributes of TOPTICA’s tunable diode lasers. They are available with wavelengths ranging from the deep UV to the mid IR (< 190 nm - 4000 nm), which is the widest spectral coverage on the market. TOPTICA’s patented pro design (DE 10 2007 028 499, US 7970024) guarantees highest stability and the best specifications resulting in cutting-edge research grade lasers. These systems help achieve milestones in a variety of fundamental research projects and are future-proof due to a fully digital interface.

  • Ultrafast Fiber Lasers

    TOPTICA’s pulsed all-fiber lasers combine SAM mode-locked ring oscillators with PM fiber architecture, which guarantee robust 24 / 7 operation  and turnkey performance. A modular design concept with erbium- and ytterbium-doped fibers is the basis for different models (1560 / 780 nm, VIS / NIR tunable output, IR / NIR supercontinuum). Thus, pulse durations as low as 25 fs or output powers of more than 350 mW can be reached. In addition, dual-color solutions enable full flexibility by providing two laser beams simultaneously.

  • Terahertz Systems

    TOPTICA’s vast expertise with diode lasers and fiber technology offers exciting opportunities for sophisticated, integrated systems for demanding applications. Innovative solutions pave the way for easy utilization of continuous or pulsed terahertz radiation with ultra-broad bandwidth and unprecedented signal-to-noise ratio.

  • Frequency Combs

    The DFC productline (Difference Frequency Combs) merges TOPTICA’s know-how in ultrafast laser oscillators with its long lasting expertise in tunable diode lasers and locking electronics. The integrated novel CERO-technology enables precise frequency referencing with these offset-free, fiber-based frequency combs. In addition, TOPTICA's tunable diode lasers in the region of 450 - 2200 nm can be phase-locked to the frequency combs. This way TOPTICA is able to provide complete, frequency referenced laser systems including wavelength meter and counter all from one source.
