VaryDisk Platform

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 femtosecond, picosecond 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

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.

APPLICATIONS

The extremely short pulse durations in the range of a few hundred femtoseconds allow material processing with almost complete evaporation of the material. Compared to picosecond pulses, the higher peak power densities allow a flexible input-coupling of the radiation into various types of material. Furthermore, high ablation efficiency can be obtained and the thermal impact on the material further minimized. Femtosecond material processing is particularly suited for drilling and precision ablation of glass.

Application examples, showing the capabilities of the VaryDisk laser system, were demonstrated in our application lab. Please consult D+G for further information.for further information.
