TDM 1.0 / TDM 2.0 Lab v2017

Thin disk pump optics for guiding up to 1 kW (1 kW version and optionally even 2 kW) of pump power multiple times over a laser active thin disk medium, such as provided by our TD12 disks. Due to its easy integration in an laboratory style optical laser setup and due to its many degrees of freedom for adjustment, the TDM 2.0 is recommended for a laboratory environment.

TDM 30 High Power

Pump power up to 30 kW (so far tested with 13 kW, due to non-availability of pump diodes with 30 kW of pump power; in multimode operation an output power of 7.8 kW was demonstrated)

Thin Disk Laser Gain Media

Mounting of thin laser crystals, thereby ensuring effective and homogenous cooling, is the key technology for disk lasers. For various laboratory applications as well as for the series production of our OEM customers, we offer pre-mounted disk laser crystals tailored to and tested under the customer’s specifications and/or operating conditions.

Helical Drilling Optic

With our trepanning optic for drilling with highest precision, micromachining can be brought to its edge. Our trepanning optic is a tool for efficient production of high-precision holes with well-defined geometry by means of helical drilling.

VaryDisk Platform

The VaryDisk platform provides the basis for four VaryDisk base versions, each being a fully functional laser system for laboratory investigations and/or industrial use. The output specifications of each VaryDisk laser system can be chosen according to our customers need by either choice of one out of four base versions (FEMTO, PICO, NANO, ENERGY), combined with various available options, or by special request. Depending on the individual choice of parameters, the VaryDisk laser system qualifies as industrial, scientific or prototype laser system. 

GigaPulse Linear Amplifier

The D+G GigaPulse is the first commercially available device achieving kW average power as well as mJ pulse energy in the short and ultrashort pulse time regime. 

The D+G VaryDisk is build in a cascading laser system starting from a seed laser amplified by a VaryDisk to a power and energy level which suits the amplification properties of the GigaPulse system - typically. Other configurations are possible as well.

We engineered the GigaPulse for the following pulse energy and average power regimes:

TDM 0.05 Compact

Pump power up to 50 W; 12, 20, or 28 passes of pump radiation; Compact Low cost; Water or Peltier cooled

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.

Large Aperture Pockels Cell v2017

The Dausinger + Giesen Pockels cell v2017 is designed to operate with high pulse energy. The large BBO crystal is used to operate the Pockels-cell with pulse energy levels of up to 200 mJ in regenerative amplifiers or even more in cavity dumped systems. It is also tested with several 100 Watt average power in pulsed operation mode.

TDM 10

Thin disk pump optics for guiding up to 10 kW of pump power multiple times over a laser active thin disk medium, such as provided by our TD20 or TD25 disks.

Customized Laser Systems

Special purpose laser systems based on the thin disk laser technology with specifications, which are not readily available at the market, can be built according to customer's demand: We help you in finding the right laser design for your application with our thin disk pump modules and thin disks. Such might be for example a simple CW fundamental mode or multimode laser, a pulsed laser oscillator, a Q-Switch laser, a cavity dumped laser, or a regenerative amplifier (see also our VaryDisk regenerative amplifier).

VaryDisk ENERGY

The VaryDisk energy is a fully functional laser system with chirped pulse amplification (CPA) for laboratory investigations and/or industrial use. The output specifications of the VaryDisk energy laser 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. Depending on the individual choice of parameters, the VaryDisk energy laser system qualifies as industrial / scientific or prototype laser system. 

Process Development

Understanding the underlying physical principles is fundamental for successful laser processing. Together with the long term experience of D+G in laser processing, we offer various equipment for analysis of our customers processes (usage is - of course - not limited to laser processes)...

VaryDisk PICO

The 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.

VaryDisk NANO

The VaryDisk nano is a fully functional laser system for laboratory investigations and/or industrial use. The output specifications of the VaryDisk nano laser 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. Depending on the individual choice of parameters, the VaryDisk laser system qualifies as industrial / scientific or prototype laser system. 

Compact Q-switch Laser

A compact Q-switch laser with 20 W average power at 515 nm and pulse energies of up to 1.5 mJ and pulse lengths of 500 ns was developed with our TDM 0.05 pump module. Upon request we can help you in building similar laser systems with our TDM 0.05 module.  

High Power Fundamental Mode Resonator

Upon request, we offer a customized laboratory fundamental mode oscillator operated in vacuum. The oscillator utilizes our TDM 30 pump module.  

The development of a prototype of a fundamental mode oscillator was funded in the framework of the BMBF (German Ministry of Education and Research) project "FOKUS" (13N11627).
