   The TiF laser series, being one of our first products, has been upgraded over the years to match the increasing demand for stability and hands-free operation from scientists all over the world. The laser comprises a selected Ti:Sapphire crystal, compact or long resonator design, electronic control of emitted wavelength (by controlling both wavelength tuning slit and one of the prisms), electronic starter unit for easy maintenance of fs regime, and an additional mirror set if broad wavelength tuning is required (see tuning curves for the laser).
   The two main models are TiF and TiF-M, the only difference being the size of the unit. The traditional TiF variant is more suitable when there is no strict space requirement and some upgrades and customization of the laser are planned after the purchase. We also recommend this version for education purposes. The new TiF-M unit has compact design and yet provides stable generation. Please see the drawings (TiF-100, TiF-100M) for exact dimensions.
   The laser is shipped fully aligned and tested for the desired specification and at normal transportation conditions the laser can be aligned by the customer following the steps described and illustrated in the laser manual. Once the laser has been aligned, little to no day-to-day maintenance is required. The amount of maintenance greatly depends on room temperature stability over time. To improve stability in poor room conditions we offer a thermostabilized main breadboard option for the TiF-M model.
   As for the cooling issue, the crystal can be cooled by moderate tap water flow or no cooling at all may be necessary with 3W pump. However, we strongly recommend using a chiller for greater stability, especially with the thermostabilized main breadboard.   

- Customer-specified design of the resonator is possible.
- Integration with the pump laser (i.e. Laser Quantum - Opus 3W, Finesse 4W, 5W, 6W or 7W) in one case on one breadboard is also possible (please see our TiF-50F models).
