Photonics West 2022

#photonicswest is about to start and we are very excited to be part of it.
Meet us at our booth 4429-11 to learn about our latest innovations for label-free imaging and quantum-dot pumping.

Conference Presentation 1: Novel picosecond fiber laser for quantum-dot excitation tunable from 770 nm to 980 nm – 26 January 2022 6:00 PM PST

Conference Presentation 2: High-stability performance of an all-fiber light source for stimulated Raman scattering microscopy – 24 January 2022 1:50 PM PST

New publication

Our first laser prototype has been running reliably since 2018 at the University of Münster and is delivering exciting results.

Check out the recent publication of Prof. Fallnich and his team, showing hyperspectral SRS imaging with the laser. Great work by T. Würthwein, K. Wallmeier, N. Lüpken, and N. Lemberger.

New publication

A very simple yet powerful image showing a contrast enhancement by a factor of almost 20 in label-free imaging.

The image is part of the recent publication by Thomas Würthwein and Kristin Wallmeier from the University of Münster, investigating the details of our PICUS DUO laser for frequency modulated CARS/SRS.

New publication

Conor Evans at the Massachusetts General Hospital and his team are using our PICUS DUO for monitoring active pharmaceuticals in skin. Check out their article about the advantages of our PICUS DUO for label-free imaging of complex and dynamic samples.

CLEO Europe and ECBO conferences

On 20 – 24 June we are participating in the CLEO Europe conference and the European Conference on Biomedical Optics.

Watch our presentations CH-3.5 and ETu4B.2 on how our laser technology is helping to establish coherent Raman imaging for point-of-care diagnostics in clinical settings.

If you missed our presentations, please contact us and we will send you a copy of the recordings.

Focus On Microscopy conference

On March 28 – 31 we are participating in the FOM2021 online conference and are excited about another opportunity to discuss coherent Raman imaging and its advantages for live cell and tissue imaging.

Join us under FOM2021 and watch our two contributions:

Enhanced Sensitivity of Coherent Raman Imaging by a Frequency Modulated Portable Light Source.

Multicolor Stimulated Raman Scattering Microscopy with a Widely Tunable Portable Ligth Source.

Photonics West 2021 resume

Photonics West 2021 was another success for Refined Laser Systems. Although we missed meeting you in person, we had fruitful and enjoyable discussions. We were particularly happy to see the many advances in the field of coherent Raman imaging and look forward to contributing to the further development of this promising field.

If you have missed our talks
11656-32: Multicolor stimulated Raman scattering microscopy with a widely tunable portable light source
11655-41: Coherent Raman imaging with enhanced sensitivity by a frequency-modulated portable light source
please contact us and we will send you a copy of the recordings.
