The VaryDisk-platform is a high energy multi-milli-Joule laser system for laboratory investigations and/or industrial use. Based on our more than 10 years experience in thin-disk laser systems, the main core of the VaryDisk-platform is a thin disk regenerative amplifier for amplication of femtosecondpicosecond or nanosecond pulses with amplification factors in the order of 106. The output specifications can be chosen according to our customers need, mainly by choice of the seed laser (multiple seed lasers are possible) and various options available.



VaryDisk FEMTO
VaryDisk (2018 version)



The VaryDisk system is based on highly sophisticated engineering with extremely high stability. What makes the VaryDisk platform unique is its ability to combine various seed lasers and to have various motorized adjustments available, in order to allow the maximum in flexibility. Due to its thin disk technology with large mode radii on the gain medium and propagation in air, high pulse energies can be easily generated without risk of damage. Special requests can be taken into consideration, such as e.g. implementation of the customers seed laser.

VaryDisk energy



The VaryDisk ENERGY is a fully functional laser system with chirped pulse amplification (CPA) for laboratory investigations and/or industrial use.



VaryDisk femto



The VaryDisk FEMTO is equiped with a femtosecond seed source, allowing ultrashort pulse durations. Especially useful for the VaryDisk FEMTO system is the variability option, alowing a motorized adjustment of the pulse duration.  



VaryDisk pico



The pulse characteristics of the VaryDisk PICO is mainly determined by the seed laser of this system. Our standard configurations includes a 6 ps seed, however other pulse durations are possible, depending on the need of our customer. The choice of pulse duration, actually determines the maximum available energy with this laser system.



The VaryDisk Series is highly customizable; parameters may change and are subject to detailed discussion with customer at the time of purchase; parameters given here are typcial realizations for the specific setup; depending on the choice of parameters, the laser system qualifies as industrial, scientific or prototype system;


Dear Customer,
Dausinger+Giesen GmbH will discontinue the following Thin Disk component as of June 30th, 2023.
Our intent is to accept orders for the part until the discontinue date and afterwards until the end of 2023 or
the correspoinding parts in stock and assembly tools to deplete, whichever comes first, we will serve _
reworking the product in the case of the damage occured during the laser operation orthe handling.
For the suggested replacement, please contact your distributor.
Discontinued Part: TD12-7-215-HD (CuW heatsink type)
Suggested replacement: TD12-7+(+) (diamond heatsink type)
*The possibility of the alternation depends on the design generation of TDM1.0.
D+G appreciates and values our business relationship and looks forward to your continued interest in our
products. While we regret any inconvenience this announcement may cause, we would like to supply your
future product requirement with our advanced technology products.

The team of Dausinger+Giesen is the winner in the European project PULSATE for a development of a green laser for additive manufacturing.
