MSHG pro

Modular amplified, narrow linewidth, frequency-doubled laser
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
Ion quantum computing & simulation
Color centers (NV/Si)
Quantum communication
Quantum sensing & metrology
Quantum physics science
Maskless lithography & laser direct writing
Holography & augmented reality

Options

FiberDock probe
Fiber coupling of probe beam.
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.
High power
At certain wavelenghts, high power tapered amplifiers are available. The option includes high-current driving electronics and a high-power capable SHG stage.
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).
Extra power
Why have one TA if you can have the power of two in the same package? By coherently adding the output of two TA chips we can increase the output power by > 80%. This TA-SHG pro XP is available for selected wavelengths.
