Passive longterm output power stability of 589 nm MSHG pro vs. SHG pro. Similar performance is achieved in a non-stabilized office space (MSHG pro in T-Rack) vs. a temperature-stabilized optics lab (SHG pro on optical table). Active power stabilization PowerLock is included in all system containing a tapered amplifier (TA).
MSHG pro
High-power, tunable, frequency-doubled diode laser for 19" rack integration
- For integration in the T-RACK or in a 19” standard rack
- Resonant frequency doubling stage
- Wavelengths: 330 .. 780 nm, linewidth < 500 kHz
- Light Provided by Single Mode PM Fibers
- With digital control DLC pro: Less drift & linewidth
The MSHG pro system, part of the UV / RGB solutions, comprises a tunable diode laser (DL pro), a high power semiconductor amplifier (TA pro) and an integrated frequency doubling stage (SHG pro). Alternatively, it is available with a fiber (FA) or Raman fiber (RFA) amplifier.
The MSHG pro laser head is the 3U 19” subrack mounted version of the TA-SHG pro head. Such, it allows for quick integration in new and existing setups. Furthermore, it enables transportability and more compact lab setups for the next generation of Quantum Technologies experiments. Please see Laser Rack Systems for the complete product family and T-RACK for a suitable rack.
The SHG stage is a folded ring cavity in bow-tie configuration with excellent thermal and mechanical stability. The system includes fully-automated push-button coupling optimization AutoAlign into the TA chip, the SHG cavity and the output fiber, as well as output power stabilization. It provides tunable laser radiation for spectroscopy, laser cooling, holography and interferometry.
The system achieves the same ultimate performance as TOPTICA's established TA-SHG pro: Unprecedented passive stability, unique locking solutions, and narrow linewidth. Each output is fiber-coupled (using FiberDock) independently to allow for flexible access. A drawer slide design enables easy service.
The laser is controlled with TOPTICA's DLC pro. With a touch screen, knobs and buttons this 3U laser controller enables a unique user convenience, combined with a low-noise operation and intelligent locking functions due to its digital architecture. It also enables a remote control of the integrated laser modules.

Specification
The MSHG pro may be included in a T-RACK and therefore be part of a complete Laser Rack System. In this case, one takes full advantage of the integrated rack solution. The MSHG pro may also be purchased for mounting in a standard 19” rack by the customer. Please inquire about requirements for mounting MSHG pro. Space requirements in the rack vary depending on the specific configuration. One unobstructed height unit has to be added below each module (MSHG pro, DLC pro) for proper thermal management. For details on rack requirements please contact TOPTICA. Finally, the MSHG pro may also be used as a table-top solution consisting of the laser head and one DLC pro subrack.
