VaryDisk PICO

VaryDisk picoThe VaryDisk PICO is a fully functional laser system for laboratory investigations and/or industrial use. 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. Depending on the individual choice of parameters, the VaryDisk laser system qualifies as industrial / scientific or prototype laser system. Compared to our other VaryDisk systems, the VaryDisk PICO is a robust system with minor complexity.


  • output power: up to 120 W (more with power upgrade)
  • pulse energy: up to 1 mJ or 4 mJ with energy upgrade and a 6 ps seed; a longer seed pulse duration will allow larger energies
  • pulse duration depends on seed laser: e.g. 6 ps other seed lasers on request
  • repetition rate: 100 kHz ... 1 MHz in the standard configuration; however even 1 kHz ... 10 kHz is possible. For low repetition rates, the output power efficiency is smaller, requiring a pump upgrade in order to keep the output power constant
  • wavelength: 1030 nm
  • beam quality: M2 < 1.3

We offer different options along with the VaryDisk PICO in order to increase the output power and/or to allow additional operating modes along with the generation of different pulse characteristics, e.g. different choices of pulse durations, wavelength, or even the simultaneous generation of pulses with different pulse characteristics in one operation mode.  Some of the available options are listed below. Please consult our team for possible combination choices and further information.


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, please consult our team...
