• High-quality output of the CF231 Tunable Quasi-CW Ti:Sapphire Laser is generated in a computer-optimized aberration-free cavity. Low threshold generation is provided by using extra-quality optics.
• The output coupler is adapted to variation of the Ti:Sapphire gain. A single set of cavity optics provides the extremely wide 695-950 nm tuning range.
• The built-in SHG unit with cylindric optics and an efficient nonlinear crystal extend the tunability range of the CF231 Tunable Quasi-CW Ti:Sapphire Laser from 350 to 475 nm.

• CF231 Tunable Quasi-CW Ti:Sapphire Laser can be supplied together with LF2210 Quasi-CW Nd:YAG pump laser.
• Wide band harmonic separators provide high-contrast spectral separation of fundamental from the second harmonic.
• Wavelength PC-control is available on request.
