(This is Soliton-i, our compact industrial laser. It's being phased out and doesn't live up to its specs these days. But we didn't have the heart to discard it, so it's still allowed to get involved here and there and gives a sense of belonging.)

Here you will find a collection of short blog articles on various topics from the fields of optics, electronics and laser technology.

  • What is a microfluidic device?

    Microfluidic devices have a wide range of uses. In this post, we discuss the definition of a microfluidic device, the difference between a microfluidic device and a microfluidic chip, and the different types of microfluidic devices that are available in the market. Definition, differences between microfluidic chips and devices, and types of microfluidic devices. A microfluidic device…

  • SPM and TERS measurements on graphs

    Special measurement methods in nanotechnology SPM measurements on graphene Studies on graphene, carbon nanotubes (CNT) and functionalized carbons currently play an important role and were the subject of the last Nobel Prize in Physics awarded to A. Geim and K. Novoselov. An important tool for investigating such substances is a Scanning Probe Microscope (SPM), such as that manufactured by Nanonics and…

  • Cleaning with laser light

    In the course of technological progress in the field of laser technology in recent years - more compact design and greater reliability - lasers have now left the laboratory and opened up new interesting applications in trade and industry. An example of this is cleaning with pulsed Q-switched Nd:YAG lasers. The driving force behind the development of laser cleaning was the…

  • PL mapper

    Characterization of thin-film solar cells Together with the IRDEP (Insitute of Research and Development on Photovoltaic Energy), Photon etc. has developed a PL mapper for the characterization of thin-film solar cells. Photoluminescence methods are often used to detect defects in a layer system such as LEDs, OFETs or solar cells at an early stage. With these weak processes, the Hyperspectral Imager can increase the efficiency or throughput…

  • P2 and P3 processing of CIGS

    Fiber laser with adjustable pulse duration enables new ablation processes P2 and P3 in the manufacture of CIGS photovoltaic modules In the manufacture of thin-film photovoltaic modules, coating processes and ablation processes, here the writing of lines, are carried out alternately on a glass plate. This is how the individual solar cells are created with the two electrodes at the top and bottom and the photovoltaic layer in the middle...

  • Process ultrasonic spectroscopy

    Although specialty chemicals have only a 26% share in the European chemical industry, they make a significant contribution to the overall European economy. This is in large part due to the need for these substances in production in a wide variety of industrial sectors such as construction, cosmetics, household, automotive and food. Titanium Dioxide Titanium dioxide (TiO2) is a very common industrial…

  • Laser Stereolithography

    Not only can light be used to measure, heat and remove material, structures can also be produced. The two most common methods are laser sintering or laser stereolithography, in which a 3D structure is created layer by layer. During sintering, powder is locally heated with the help of a laser beam until it fuses in a targeted manner. Macro laser stereolithography…

  • Tunable IR laser sources for near-field microscopy

    The word "nano" is on everyone's lips in many areas today. On the one hand, there is certain information about a geometric size, on the other hand, this word refers to a new generation of particles that have special properties due to their size that the same substance, only slightly larger, no longer shows. Whether nanoparticles in colors,…

  • Materials analysis laboratory

    Raman spectroscopy Two different Raman spectrometer systems are available for structural analysis of materials. Firstly, a large laboratory system from Renishaw with three different laser excitation wavelengths (532nm, 632.8nm and 785nm), high transmission and high spectral resolution. On the other hand, a fiber-coupled compact Raman spectrometer (at 532nm excitation) for quick overview spectra. Laboratory Raman spectroscopy The Raman spectrometer from Renishaw is particularly characterized by its…

  • Coherent Anti-Stokes Raman Scattering (CARS)

    CARS is a spectroscopy method that has been known for decades and was used in particular to study combustion processes such as in engines and car engines. The CARS effect is a third-order nonlinear effect. Two laser beams (pump beam ωP and Stokes beam ωS) cross in a medium and the anti-Stokes beam ωaS is generated. With this, based on the Raman selection rules, the…
