Utilization of existing Ti:Sapphire laser
Compatible with standard holders
With the use of the FemtoWHITE 800 you eliminate the need for
more complex laser systems like cavity dumped oscillators or
two synchronized oscillators.
Pump the FemtoWHITE 800 with an 800nm range femtosecond
laser and enjoy the polarized octave spanning output without
the hassle of fiber cleaving and handling.

The tailored dispersion curve of the FemtoWHITE 800 enables
stable, low-noise supercontinuum generation using your existing Ti:Sapphire.
Coupling in and out of the device is easily realized by using
standard microscope objective with high magnification
mounted on XYZ stages.
Technical advantages
- Optimized for 800nm range fs pumping
