Amphos GmbH

banner_Logo_amphosAMPHOS (“Amplifying Photonics”) is a spin-off of the renowned Fraunhofer ILT and RWTH Aachen University (LLT, TOS). AMPHOS manufactures ultrashort pulse laser systems with extremely high average power (>>100W) for scientific and industrial applications based on longterm experience in development of InnoSlab laser systems, opto-mechanical design and thermo-mechanical mounting technology. AMPHOS establishes a new standard in stability and reliability of ultrashort pulse laser systems. The inherent simple setup of the InnoSlab Amplifier in combination with industrially proven and optimized components allows for a new generation of robust ultrashort pulse laser systems. AMPHOS – your partner for laser technology in science, R&D and industry.


AMPHOS Lasersystems are based on InnoSlab Amplification Technology. InnoSlab amplifier systems are characterized by a very simple beam path. No CPA and no regenerative beam path is necessary to achieve large amplification with high efficiency.

The extremely compact setup – the distance between the folding mirrors is just 35mm – leads to a robust, quasi monolithic package.

Principle of Amphos highpower InnoSlab amplifier


Due to the line shaped amplification volume of the InnoSlab amplifier the pumping system is highly efficient. No symmetrization of the diode laser radiation is necessary.

The usage of Yb:YAG as active medium allows high average power due to the stable YAG crystal and low quantum defect as well as ultrashort pulses in the 500fs range due to the broad emission spectrum.

As the InnoSlab laser is a “crystal” laser, the time-bandwidth spectrum is diffraction limited.

Scalability of output power is also simple with InnoSlab lasers. By increasing the crystal width the output power can be increased keeping the high beam quality and without increasing the demand on brightness of diode lasers. This is unique for diode pumped solid state lasers.
