TA-SHG pro: Available wavelengths and output power
TA-SHG pro
High-power, tunable, frequency-doubled diode laser
The TA-SHG pro system, part of the UV / RGB solutions, comprises a tunable diode laser, a high power semiconductor (TA) and an integrated frequency doubling stage (SHG pro). Alternatively, it is available with a fiber (FA) or Raman fiber (RFA) amplifier. The SHG stage is a folded ring cavity in bow-tie configuration with excellent thermal and mechanical stability.
The system now includes fully-automated push-button coupling optimization 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, optical data storage, holography and interferometry.
The rack-mounted version of TA-SHG pro for integration into T-RACK is available as MSHG pro.

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.
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). -
