VaryDisk FEMTO
The VaryDisk FEMTO is a fully functional laser system especially suited for laboratory investigations. The VaryDisk FEMTO is equiped with a femtosecond seed source, allowing ultrashort pulse durations. Additional specifications can be chosen according to our customers need by either combination of one of our four VaryDisk base versions, or with various available options listed below. Especially usefull for the VaryDisk FEMTO system is the variability option, alowing a motorized adjustment of the pulse duration. Furthermore, additional seed lasers can be used for an even larger flexibility with respect to the available pulse durations. Depending on the individual choice of parameters, the VaryDisk FEMTO qualifies as industrial / scientific or prototype laser system.

OPTIONS
We offer different options along with the base versions of the VaryDisk system in order to increase the output power (power upgrade 240 W) 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.
motorized compressor (MC) for an adjustable pulse duration adjustable 2 ps … 500 fs
shorter pulse durations < 350 fs (even shorter upon request: FEMTO+)
multiple seed lasers (e.g. fs, ps, ns) for mixed pulse trains (MPT)
higher repetition rates of up to 1 MHz
pulse picker (PP-6, PP-9, PP-12)
active stabilizer (RMS+) for improved RMS
high speed warm up routine (HS)
customizable network Interface
515 nm
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.

Long term stability of VaryDisk FEMTO after powering on for 2hours: mean = 130.25 W, RMS 0.94 W; the laser system was delivered without stabilization, which, however, in the future will be standard for our VaryDisk systems; every 10th data point is shown;
Scanner, Helical Drilling Optic
In order to bring the laser pulses to your workpiece, we offer different kinds of micromachining tools, such as third party scanners, or our own helical drilling optics.
SHG, THG Option
In order to allow the generation of different wavelengths, the standard wavelength of 1030 nm can be frequency doubled to 515 nm. Even the generation of UV light is possible.
Femto+ Option
By use of different gain materials, the amplification bandwidth of our VaryDisk system can be increased. This way, even shorter pulse durations are available for the VaryDisk femto, pico, and/or energy.
Aditional Seed Laser(s)
The VaryDisk femto, pico, and/or energy system can be operated with additional seed lasers in order to allow an additional flexibility in the choice of pulse durations. Along with the original pulse duration of the base system, pulses with picosecond and/or nanoseconds are additionally available. Even pulse to pulse switching is possible, if requested so by our customer.
Twin Option
Different base systems of the VaryDisk can be combined in order to increase the flexibility and cost effectiveness of this laser system. One possible combination is the use of the femto and pico system simultaneously by adding another ps-seed to the femto version.
Flexibility Option
The VaryDisk femto laser system with flexibility option offers unprecedented flexibility in the choice of pulse duration from the femtosecond to the microsecond range.
