The TiF-SP laser system offers the shortest available pulse duration in the TiF family of Ti:S femtosecond laser oscillators. It is a robust tool for cutting-edge ultrafast research.

The system can be supplied as a stand-alone version for pumping with an external pump laser or a version with an integrated industry-standard pump laser on site or at our factory. However, the dimensions of the Ti:S laser head are the same for either version, the stand-alone version may later be fitted with an integrated pump laser at minimum additional cost. The acceptable pump laser power for the TiF-SP is up to 10 W.

The system is designed to operate 24/7 as a seed oscillator for our larger amplifier systems and thus inherits all the stability-enhancing design features. The system may be supplied pre-tuned to one of the available configurations (12, 15, 30 or 40 fs), with all the components inside the box being the same, or it can be equipped with an additional option to switch between these ranges. In this case, the broadness of the central wavelength tuning range of the spectrum increases with increasing pulse duration.

There are three pre-designed factory supply packages:
- a manual package includes a push-button non-automatic electric starter and allows manual tuning of the wavelength and pulse duration setting by using micrometer screws placed on the walls of the laser box.
- a basic factory package includes a simple USB motorized wavelength tuning slit and a push-button non-automatic electric starter. Wavelength tuning and calibration with this package is done via step number information in basic Windows software.
- the “Auto” factory package includes built-in spectrometer and power meter, single-touch wavelength tuning with presets, configurable widget software, active power lock function and automatic mode-lock start and monitoring. With this package the system boasts exceptional long-term stability and longer uninterrupted runtime.

The monolithic thermostabilized body of the TiF-SP provides excellent passive stability of the output radiation parameters.

An external prism pair or a tunable pulse compressor (the APC-Pro or APC-Kit units) for output pulse chirp compensation and pre-compensation are also available.
