SHG pro: Schematic setup
SHG pro
Frequency-doubling unit
- Compact module for resonant frequency doubling
- Best cw conversion rates
- Wavelengths: 205 .. 800 nm, linewidth dependant on seed laser
- Highest stability and Ease of Use: pro technology
- For Ti:Sapphire, dye, gas, fiber and diode lasers
The SHG pro is the device of choice, if existing lasers are to be frequency doubled. Designed in TOPTICA’s pro technology, it unites highly stable performance and convenient operation. Mirror and crystal holders can be adjusted without opening the resonator cover. A wide range of non-linear crystals covers SHG wavelengths from 205 to 800 nm. Together with the customer TOPTICA will find the optimum parameters for frequency doubling. A professional installation by TOPTICA ensures the specified performance is achieved.

Options
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.
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.]
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
