Sirah Lasertechnik’s MixTrain Series 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 (Ti:Sa) laser like the Matisse C or Matisse 2 T Series, while the other laser is a powerful fixed wavelength fiber laser.

The MixTrain 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.

Within MixTrain 5/10, 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.

For MixTrain 15 systems, the powerful fixed wavelength fiber laser operates at 1550 nm, providing a sum wavelength range of 488 nm to 615 nm with more than 2 W of output power at 520 nm, and a difference wavelength range of 1650 to 2800 nm with more than 200 mW output power at 1700 nm.

For MixTrain 19 systems, the powerful fixed wavelength fiber laser operates at 1950 nm, providing a sum wavelength range of 515 nm to 664 nm with more than 1.5 W of output power at 555 nm, and a difference wavelength range of 1090 to 1750 nm with more than 100 mW output power at 1350 nm.
