FA-FHG pro

Fiber amplified, narrow-linewidth, frequency quadroupled laser

The atoms decide the laser wavelength, not the other way around

FA-FHG pro

Fiber amplified, narrow-linewidth, frequency quadroupled laser

Nonlinear frequency conversion techniques access wavelengths that cannot be generated directly from laser diode technology. Via second or fourth harmonic generation, TOPTICA laser systems can access the UV, blue, green, yellow and orange spectral ranges at high powers. TOPTICA offers tunable, single-frequency systems at any wavelength between 244 nm and 340 nm, employing ultra-stable seed lasers, power amplification in fiber amplifier or Raman fiber amplifier, and a proprietary bow-tie cavity design – all in established pro technology.

Your Benefits

For all atoms and ions

Lasers at most laser wavelengths between 244 nm and 390 nm to address most of the relevant UV and deep UV transitions for quantum applications.

Narrow linewidth

The DL pro patented design results in a narrow linewidth for applications where a low frequency noise is required.

Customizable

Configure your SHG with the features you require. Every quantum system has its own personality. That’s why our FHG systems are modular. Need a variable probe beam? Easy. Want to integrate manipulate the seed light or add a noise eater? We love those challenges. It’s a bit like Lego for lasers: we click together exactly what you need.

Applications

Quantum physics science

TOPTICA's products are widely and successfully used for scientific applications in fundamental quantum technology. In these fields quantum physics, quantum optics, atom optics, photonics, statistical physics and related fields are investigated in order to understand the basics of quantum technology.

Atom quantum computing & simulation

Atoms are excellent quantum systems for both quantum computing and quantum simulation. They can be ultimately controlled in all of their quantum states and even millions..

Ion quantum computing & simulation

Ions are ideal qubits for quantum computing and simulation due to their excellent isolation and precise quantum-state control.
They are ionized, laser-cooled, and trapped in electromagnetic traps under ultra-high vacuum using specialized lasers and fields.

Quantum sensing & metrology

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.

Angle-resolved photoemission spectroscopy (ARPES)

The experimental technique is used in condensed matter physics probes the allowed energies and momenta of the electrons in a material. Ultraviolet lasers are key to deliver to the sample a monochromatic, polarized, focused, high-intensity beam. ARPES is best suited for the study of one- or two-dimensional materials.

Maskless lithography & laser direct writing

In modern microlithographic systems compact violet and UV diode lasers have taken the place of bulky gas lasers or HeCd lasers. The superior performance of diode lasers enable improved up-times, lower cost of ownership and qualities of written features, which haven’t been imagined before this paradigm shift.

Holography & augmented reality

Holography has evolved from an artistic curiosity into a cornerstone technology for next-generation optical systems. From augmented reality (AR) displays and automotive lighting to precision metrology, data storage, and optical security, holography today enables engineers and designers to shape, direct, and control light with unprecedented precision.

Options

SUV

A modified FHG cavity design allows for unprecedented DUV output power and stability. Warranty included.

AutoAlign

Automated alignment of beams coupled to the cavity and FiberMon. No compromising of passive stability - AutoAlign is only activated on user request.

EOM

An EOM before the doubling cavity allows to independendly create the PDH signal for laser locking. Advantageous for nondisturbed DL pro operation and maximum mode-hop-free tuning range in case of SHG cavity, and significant RIN reduction and suppression of UV sidebands in case of FHG cavity.

Narrow linewidth

The DL pro fundamental master laser is replaced by a narrow-linewidth version. Other master lasers (DFB/DBR) available upon request.

Advanced Locking

Various lock options from side-of fringe frequency stabilization to PDH linewidth narrowing available. Modules like DigiLock 110 or PDH/DLC pro can be installed in the DLC ext extension rack, with shortest-possible cable length right next to the laser head. For the most demanding applications you can use the FALC pro (see Laser Locking Electronics).
