MSHG pro

Modular frequency doubling cavity

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

MSHG pro

Modular frequency doubling cavity

The MSHG pro is the 19” rack-mountable version of the SHG pro and it seamlessly integrates into TOPTICA’s T-RACK or other suitable 19” racks. The MSHG pro laser head includes a tunable diode laser, a high-power semiconductor amplifier and an integrated frequency-doubling (SHG) stage. The SHG stage is a folded ring cavity in bow-tie configuration with excellent thermal and mechanical stability. On request, it is also available with a fiber (FA) or Raman fiber (RFA) amplifier.

When operated in TOPTICA’s T-RACK, the MSHG pro has the same optical specifications as a fiber-coupled SHG pro system. The system includes fully-automated push-button coupling optimization AutoAlign into amplifier chip, SHG cavity and output fiber. Moreover, MSHG pro supports output power stabilization. The unit consumes a total of 4 Rack Units (RU) in height, including an extra 1 RU blanking front panel recommended for thermal isolation between laser units.

The MSHG pro laser head is controlled with TOPTICA’s DLC pro. Its digital architecture enables low-noise laser operation, intelligent locking functions and remote control via Ethernet.

Your Benefits

For all atoms and ions

Lasers at all laser wavelengths between 330 nm and 780 nm to address most of the relevant visible and UV transitions for quantum applications.

Customizable

Configure your MSHG with the features you require. Every quantum system has its own personality. That’s why our MSHG systems are modular. Need a variable probe beam? Easy.

Clearing optical tables

Like all building blocks of TOPTICA’s Laser Rack Systems, the MSHG pro is designed to clear optical tables and to stow away lasers into a 19" form factor. It is ideally suited for integration into TOPTICA Laser Rack Systems that allow researchers to focus on their experiment rather than on their laser system.

Highly stable

The SHG stage is a folded ring cavity in bow-tie configuration with excellent thermal and mechanical stability. Moreover, it offers passive vibration isolation decoupling the lasers from the environment.

Easy access and service

The MSHG pro modular laser unit features a full-extension pull-out mechanism and dynamic cable management, both ensuring easy access to the laser modules.

Applications

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.

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.

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

Light-field recording with phase information, for recording of patterns and pseudo-3D images. Coherent diode lasers at 407 nm, 457 nm, 514 nm, 647 nm or other wavelengths in the RGB region, and even in the UV region with power levels of several 100 mW have become the optimal choice for holography – especially in industrial applications. Whereas the original sources were bulky and operated at a fixed wavelength, diode lasers are tunable, so they perfectly match the user requirements.

Options

FiberDock probe

Fiber coupling of probe beam.

EOM

Electro-Optic Modulator for error signal generation (alternative to laser current modulation).

Locking and other electronics modules

For DLC pro, the versatile DLC pro LOCK option is available as well as FALC pro and PDH/DLC pro modules. With DLC ext a number of analog locking modules is available.
