What users like about the FemtoLux
We, SuperbIN company, are provider of customized laser machine systems. One of main requirements (besides specifications) from our customers are reliability and maintenance free operations. We have been using FemtoLux 30 from Ekspla for 4 months under intense conditions. FemtoLux 30 from Ekspla delivers stable parameters, maintenance free operation and establishes itself as reliable laser source for micromachining applications.
In general, we like the extended capabilities of the laser output with respect to higher power and rep rate. We were able to make good cuts very quickly. The higher rep rates help us with edge quality. We have been able to cut thicker materials than with our other laser sources. We really like the fact that it is easier to work with. The compact chiller and the rack mount controller are great features and save us a lot of space. The technical support has been very responsive and complete. We have already ordered a second laser.
The FemtoLux30 has been very easy to use with the PI stages (XY and Rotation axes for the samples plus the typical Z axis for the focusing lens) in our micromachining system. As someone who worked with Ti:sapphire lasers (much shorter pulses) in the past, I am very pleased with how robust the FemtoLux system is.
FemtoLux 30 femtosecond laser system has been valuable in our laboratory, demonstrating its capability in various material micromachining tasks. It stands out for its low maintenance requirements, and with the availability of harmonics and burst mode, it efficiently processes different materials with high quality.

Tuning Polymer-Backbone Coplanarity and Conformational Order to Achieve High-Performance Printed All-Polymer Solar Cells
Yilei Wu, Yue Yuan, Diego Sorbelli, Christina Cheng, Lukas Michalek, Hao-Wen Cheng, Vishal Jindal, Song Zhang, Garret LeCroy, Enrique D. Gomez, Scott T. Miller, Alberto Salleo, Giulia Galli, John B. Asbury, Michael F. Toney, and Zhenana Bao. Nat. commun . 2024, 15, 2170.
All-polymer solar cells (all-PSCs) offer improved morphological and mechanical stability compared with those containing small-molecule-acceptors (SMAs). They can be processed with a broader range of conditions, making them desirable for printing techniques. In this study, we report a high-performance polymer acceptor design based on bithiazole linker (PY-BTz) that are on par with SMAs. We demonstrate that bithiazole induces a more coplanar and ordered conformation compared to bithiophene due to the synergistic effect of non-covalent backbone planarization and reduced steric encumbrances. As a result, PY-BTz shows a significantly higher efficiency of 16.4% in comparison to the polymer acceptors based on commonly used thiophene-based linkers (i.e., PY-2T, 9.8%). Detailed analyses reveal that this improvement is associated with enhanced conjugation along the backbone and closer interchain π-stacking, resulting in higher charge mobilities, suppressed charge recombination, and reduced energetic disorder. Remarkably, an efficiency of 14.7% is realized for all-PSCs that are solution-sheared in ambient conditions, which is among the highest for devices prepared under conditions relevant to scalable printing techniques. This work uncovers a strategy for promoting backbone conjugation and planarization in emerging polymer acceptors that can lead to superior all-PSCs.
