Self-Adjusting Plasma Process Control Unit (SappCU) The aim of the project is to develop, implement and verify the self-regulating control of a process for
plasma-assisted surface hardening of metallic components based on laser-optical measurement of the plasma-activated gas composition.
The innovative aspect here is the in-process use of laser absorption spectroscopy for non-invasive, in-situ measurement of the
plasma-activated gas composition within the plasma reactor, as well as the development of a new control algorithm for the plasma process
based on the recorded sensor data. Partner

INnovative plasma nitriding through dynamic PROcess control via optical Frequency combs (InPro-F) Nitriding and nitrocarburizing processes are used industrially to improve the hardness, wear resistance and fatigue
strength of metallic surfaces. Due to its simpler handling, gas nitriding has been common practice to date, accounting for around 93% of global
annual plant sales. The plasma nitriding process, which is much more favorable in terms of environmental impact, resource utilization and flexibility
with regard to treatable materials, has so far had only limited market acceptance. The main reasons for this are the lack of key figure-controlled
process management to date. The provision of dynamic process control based on in-situ measured values can represent the technological leap in plasma
nitriding that is being sought. Laser absorption spectroscopy in the mid-infrared spectral range provides a measuring technique for recording the
concentration of process-relevant molecules in situ and making them available for process control. Partner

mid-infrared system utilizing LEVEl-crossing chirp-Spectroscopy in quantum-cascade-laser (LEVES) The LEVES cooperation project aims to develop a new type of compact mid-IR process monitoring system for in-situ process
monitoring in the semiconductor industry, plasma process diagnostics, environmental and exhaust gas monitoring. Its core is a cost-effective
Fabry-Perot-Cavity quantum cascade laser (FP-QCL) with an innovative, groundbreaking approach to tailored chirped emission with a spectral tuning range
of 20 cm-1. This device is a game changer in the spectroscopy industry and was previously not available on the world market. Thanks to its
broad tunability, it covers broad and overlapping absorption features of multiple chemical compounds, allowing the systems to quantify each molecule by
spectral analysis. Partner

MEMS based photothermal SPECtrometer for PROtein and dna analysis for laboratory and production (MEMSpecPro) To provide a solution for the analysis of a few nanoliter samples of expensive biosamples, such as DNA and proteins, a MEMS microchip-based system was developed in collaboration between Fourien Inc, neoplas control GmbH and Fraunhofer IAF as part of the MEMSpecPro project. Canadian partner Fourien Inc. is designing and developing the MEMS microchips (microfluidic cantilever), the optics for the spectrometer and the software for control and data processing. In order to be able to use the MEMS microchips for the spectroscopic task, a specially adapted infrared laser module was developed in cooperation with the German partners neoplas control GmbH and Fraunhofer IAF and made available for system integration. The performance of this modular solution was successfully demonstrated in the project result. Partner

Mid InfraRed Innovative lasers For Improved SENSor of hazardous substances (MIRIFISENS) The mid-infrared range (MIR) is the preferred wavelength range for a range of applications including high
sensitivity trace gas detection, chemical emissions monitoring, process control and biological sensors. In the field of MIR laser sources,
further technological advances had to be made, with tunability, space requirements, power consumption and wallplug efficiency being
decisive features with regard to the specific fields of application.
In the MIRIFISENS project, state-of-the-art micro- and nanofabrication techniques were used to drive the necessary technological advances
in sensitivity, selectivity, multi-gas capability, compactness, efficiency and cost effectiveness. Partner
