DL-SHG pro

Narrow linewidth, frequency doubled laser

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

DL-SHG pro

Narrow linewidth, frequency doubled laser

Nonlinear frequency conversion techniques access wavelengths that cannot be generated directly from laser diode technology.

The grating stabilized diode laser SHG pro is a medium power solution, for applications such as spectroscopy of atoms, ions and molecules, laser cooling and interferometry. Designed in TOPTICA’s proprietary pro technology, it combines best performance and ease-of-use. The system now includes fully-automated push-button coupling optimization into the SHG cavity and the output fiber. The package comprises a DL pro laser head.

With the AutoAlign option the systems can offer a fully-automated push-button coupling optimization into the SHG cavity and the output fiber.

The rack-mounted version of TA-SHG pro for integration into T-RACK is available as MSHG pro.

Your Benefits

For all atoms and ions

Lasers at all laser wavelengths between 330 nm and 685 nm to address most of the relevant visible and UV transitions for quantum applications.

For all modern holographic recording media

Lasers at all wavelengths between 330 nm and 685 nm to optimize absorption in all relevant all photopolymers and photoresists from RGB down to the UV.

Narrow linewidth / long coherence length

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 SHG systems are modular. Need a variable probe beam? Easy. Want to integrate a fiber amplifier, 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.

Color centers (NV/Si)

Nitrogen-Vacancy (NV) and Silicon-Vacancy (SiV) centers are two prominent types of color centers (optically active point defects) in diamond, widely studied for their potential in quantum technologies such as sensing, metrology, and computing. They offer complementary properties for different applications.

Quantum communication

Quantum communication is redefining how information is transmitted, secured, and trusted. At the heart of this technological revolution are high-performance laser systems that generate, control, and stabilize light at the quantum level.

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.

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

AutoAlign

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

Fiber delivery

Fiber Delivery (FD) is optionally available with TOPTICA's patented fiber coupler FiberDock and a suitable polarization maintaining (PM) fiber. FiberDock provides highest single-mode fiber coupling efficiencies, easy alignment and at the same time highest stability. For most lasers, we specify a PER behind fiber of >20 dB with our Fiber Delivery option. Please also inquire about Long Life and High Power fibers as well as fiber splitters. Optical isolation is mandatory for fiber coupled diode laser systems.

FiberMon

Allows measurement of the SHG output power propagating in a single-mode, polarization-maintaining (SM-PM) fiber for PowerLock and AutoAlign. Two wavelength regions are available.

EOM

An EOM before the doubling cavity allows to independently create the PDH signal for laser locking. Advantageous for maximum mode-hop-free tuning range.

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).

Double Piezo Lock

High-bandwidth stabilization of the SHG pro resonator.

Intra cavity EOM

The TA-SHG pro F variant features an intra-cavity EOM which provides two feedback channels. One is used for fast adjustments to ensure the superb locking performance, the other guarantees the high robustness of the lock. The locking performance is ideal for clock transitions and Rydberg transitions.

Upgraded to TA-SHG pro

For more output power the system can be upgraded to TA-SHG pro.

19" Rack Integration

Modular integration into 19" industry rack to save space and ensure mobility.
