AVAILABLE COLLIMATIONS (TDM 1.1)
The TDM 1.1 comes with one collimation, which will define the size of the pump spot along with the used fiber core diameter. The collimation can be exchanged easily at some later time.
For the TDM 1.1 we have various standard collimations available. The tabular below shows the available magnification with respect to the used fiber core diameter. The fiber core diameter can vary between 400 um and 1 mm. Other collimations are available upon request.

ILABLE COLLIMATIONS (old TDM 1.0)
The older version of the TDM 1.0/2.0 comes with one collimation, which will define the size of the pump spot along with the used fiber core diameter. The collimation can be exchanged easily at some later time.
For the TDM 1.0 we have various standard collimations available. The tabular below shows the available pump spot diameters depending on fiber core diameter and collimation (K1-K13). Whereas all possibilities are avaible for the TDM 1.0 with 24 passes, the available pump spot sizes for the TDM 1.0 with 48 passes are marked in green.

For laser operation dust-free environment is required. Dust will cause slow degradation of the laser disk surface and output power in continuous wave operation and can cause disk damage in pulsed operation. If the set-up is mounted on a breadboard this breadboard should be placed on a flat surface. Don’t use any small supports e.g. to realize a three-point-support.
A water connection is necessary for operating the TDM 1.1 thin disk module. The following specifications of the cooling water connection must be fulfilled (if other specifications are needed, please consult our team for realizability):
- pressure: 2..3 bar
- temperature: 10..25 °C
- laser disk flow rate: 1 ... 3 l/min (1 l/min is sufficient for a pump power below 200 W, higher water flow is recommended for higher pump power; for pump spot sizes > 4 mm and pump power densities > 2 kW/cm2, a flow rate of 3 l/min is recommended)
- other parts flow rate: > 0.5 l/min
- connections: standard fittings for tubes with an outer diameter of 6 mm
- quality: roughly filtered, deficient in lime
