SFM / DFM MixTrain
Frequency-Mixing in Periodically Poled Crystals.
The MixTrain is using quasi-phase matching in periodically poled crystals for sum- or difference frequency mixing of two cw-lasers. Typically, one of the lasers will be a tunable Titanium:Sapphire like the Matisse while the other laser is a powerful fixed wavelength fiber laser. The system uses a motor controlled translation stage for changing the period of the crystal and a temperature stabilized oven capable of heating up to 180°C. All optics for beam shaping, polarization control, beam combination, and beam separation are included. An optical diode isolates the fiber laser input from back reflections from the setup.

The doubled fiber laser at 532 nm can be ordered with a second beam output for the residual 1064 nm. The MixTrain Optics can be used for 532 nm and 1064 nm. A shift mirror construction in the pump path allows for easy change between the two input wavelengths for the MixTrain with minimal readjustment.
