ProductDescription (only for enhanced product entries)
diode lasers

Diode lasers combine plug-and-play operation, compact form factor and maximum performance. TOPTICA offers single-mode diode lasers, multi-color lasers, single-frequency lasers, and tunable diode lasers for demanding applications in biophotonics, industrial metrology and quantum technology. TOPTICA provides the widest wavelength coverage of diode lasers on the market (190 – 3500 nm).

distributed feedback lasers

TOPTICA’s DLC DFB pro lasers integrate both distributed-feedback (DFB) and distributed Bragg reflector (DBR) lasers. Available wavelengths include 633 nm and the entire range from 760 nm to 3500 nm. Three laser heads accommodate different diode packages. Due to the absence of alignment-sensitive components, the DLC DFB pro lasers exhibit an exceptional stability and reliability.

external-cavity diode lasers

TOPTICA offers ECDLs with unique tuning capabilities. The CTL lasers tune up to 110 nm without any mode hop. Finding resonances of quantum dots or micro resonators as well as spectroscopy has never been easier. TOPTICA continues to provide the DL pro, which is now available at even more wavelengths and is well suited for laser cooling and many other AMO experiments.

femtosecond lasers

Offset-free frequency combs using difference frequency generation and patented CERO ("zero-νCEO") technology, wavelength conversion to any desired wavelength between 420 nm and 2200 nm.

frequency combs (equipment for generating …)

TOPTICA’s Difference Frequency Comb (DFC) is a compact, robust, high-end solution featuring turn-key operation in a 19 inch format. The patented CERO technology uses difference frequency generation for an all-optical phase-lock of νCEO. Thanks to its intrinsic stability, the DFC is the number one choice for anyone looking for high-end performance combined with a high level of robustness.

frequency doubling (nonlinear crystals and related equipment for …)

TOPTICA provides frequency-doubled continuous-wave diode and fiber lasers. The wavelength range covers 330 nm – 780 nm with up to 20 nm of tuning. In addition, stand-alone resonant frequency-doubling units are available.

frequency quadrupling (nonlinear crystals and related equipment for …)

TOPTICA provides frequency-quadrupled continuous-wave diode and fiber lasers based on two cascaded frequency-doubling stages. Available wavelengths range from 190 nm to 390 nm with up to 10 nm of tuning. Furthermore, the novel Super-UV technology guarantees long-term stable operation and higher powers at DUV wavelengths.

laser guide stars (equipment for …)

TOPTICA Projects offers high-power cw Guide Star lasers, delivering more than 20 W of optical output power, tunable around 589 nm (sodium resonance). These systems are currently in use at all major optical telescopes and provide an outstanding performance.

laser spectroscopy (equipment for …)

TOPTICA offers industrial and research grade lasers for spectroscopy with an ultra-broad wavelength coverage: 190 nm – 0.1 THz. TOPTICA lasers deliver narrow-linewidth emission that is tunable – in some systems up to 110 nm wide without a single mode hop.

High-end, turn-key difference frequency combs and terahertz systems complement the portfolio for the most demanding spectroscopy applications.

narrow-linewidth lasers

All of TOPTICA’s tunable diode lasers offer a narrow linewidth of typically 100 kHz, corresponding to coherence lengths of almost 1 km. By stabilizing these lasers even further with TOPTICA’s locking electronics, linewidths below 1 Hz are possible.

nonlinear frequency conversion (equipment for …)

TOPTICA provides tunable continuous-wave laser systems including nonlinear frequency conversion for accessing the wavelength range from 190 nm to 4000 nm. The conversion processes are second-harmonic generation and optical parametric generation.

optical parametric oscillators

TOPTICA provides a continuous-wave optical parametric oscillator system: The DLC TOPO emits Watt-class output power levels almost continuously between 1.45 μm and 4.0 μm. Driven by the digital laser driver DLC pro, it provides unprecedented ease of use.

semiconductor lasers

TOPTICA is renowned for providing the widest wavelength coverage of diode lasers on the market (190 – 3500 nm), providing high-power diode lasers with great ease of use even at exotic wavelengths. TOPTICA diode lasers enable a big variety of demanding applications in quantum optics, spectroscopy, biophotonics, microscopy, test & measurement, as well as materials inspection.

semiconductor optical amplifiers

TOPTICA offers tapered semiconductor optical amplifier systems and amplified laser systems with the widest spectral coverage and highest power: between 660 nm and 1495 nm with single mode emission and powers up to 4 W. Tunable, single frequency, narrow linewidth and convenient to control and operate.

synchronization of lasers (equipment for the …)

TOPTICA offers solutions for synchronization of ultrafast fiber laser and continuous-wave (cw) lasers. Synchronized femtosecond fiber lasers are a key element for applications like time-resolved microscopy and pump-probe spectroscopy. Phase and frequency locking of TOPTICA’s broad portfolio of tunable cw diode laser is supported by a range of versatile laser locking electronics.

tapered amplifiers

TOPTICA offers optical amplifier systems and amplified laser systems with the widest spectral coverage and highest power: between 660 nm and 1495 nm with single mode emission and powers up to 4 W. Tunable, single frequency, narrow linewidth and convenient to control and operate.

terahertz radiation

TOPTICA provides systems and components for time-domain and frequency-domain terahertz generation. For pulsed applications, the TeraFlash sets new standards in terms of dynamic range, bandwidth and measurement speed. For continuous-wave spectroscopy, the TeraScan systems combine ease of use with best-in-class frequency resolution. The TeraSpeed is an ultrafast terahertz screening platform.

See our videos on Teraflash and Terascan!

THz detectors

TOPTICA offers receivers for coherent and incoherent terahertz detection. Photoconductive antennas (i.e., coherent detectors) enable phase-sensitive measurements with a high dynamic range in both time-domain and frequency-domain applications. Schottky diodes (incoherent detectors) lend themselves to fast terahertz imaging tasks.

THz sources

TOPTICA’s terahertz sources employ photoconductive antennas, which convert near-infrared laser radiation to terahertz light. TOPTICA offers modules both for time-domain and frequency-domain applications.

All of TOPTICA’s photoconductive antennas come equipped with a silicon lens and SM/PM fiber pigtail, and can be integrated in the terahertz platforms TeraScan, TeraFlash and TeraSpeed.

tunable lasers

TOPTICA offers various tunable diode laser systems. The combined spectral coverage is from 190 nm to 3500 nm, powers up to 4 W (TA), mode-hop-free tuning up to 110 nm (CTL).

ultrafast lasers

TOPTICA's FemtoFiber lasers provide reliable femto-/picosecond pulses based on polarization-maintaining fibers and SAM mode-locking. Different models (1560/780 nm, VIS/NIR tunable output, IR/NIR supercontinuum, short-pulse) cover a wide range of applications, e.g. time-domain terahertz, microscopy, attoscience and as seed lasers.

ultraviolet lasers

TOPTICA provides lasers in the UV range from 190 nm – 390 nm. Proprietary technology and high-end clean room manufacturing capabilities enable stable long-term operation at all wavelengths.
