« The specifications of the Alcor 920-4 laser solution (80MHz femtosecond laser with 4W of output power at 920nm) are to our knowledge quite unique in the commercial laser landscape. The imaging performances achieved in our study can not be matched with existing alternative solutions to our knowledge without compromising in recording throughput and SNR. »Lamiae Abdeladim, Adesnik lab, University of California, Berkeley, USA
« The ALCOR 920-4W laser is compact, light, and portable. It can be easily set up by one person. It is powerful enough to use with large field-of-view multiphoton imaging systems. It has a built-in prechirper with a large negative-chirp range (-60,000 fs^2) to compensate for systems with a large amount of group delay dispersion. »Che-Hang Yu, University of California, Santa Barbara, USA
« ALCOR 920 nm laser is suitable for in vivo two-photon imaging of mouse brain. It enables us to record green calcium signals of visually-evoked soma, dendrite and even spine activities of V1 neurons with high contrast by the aid of pre-installed GVD compensation module. Miniaturized and low maintenance lasers have been long awaited in the field of two-photon imaging. »Satoru Kondo, Ph.D., Division of Imaging Core, International Research Center for Neurointelligence, Institutes for Advanced Study, The University of Tokyo
« The ALCOR 920 LASER (with integrated GDD pre-compensator and XSight AOM) , is a compact, versatile and powerful tool for 2-photon excitation/activation and multi-photon laser ablation in biological samples. »Matteo RAUZI, Ph.D., University Côte d’Azur, Valrose Biology Institute, CNRS, Inserm, France
« Its compactness, ease of installation, fast warmup, great beam and pulse characteristics make the air-cooled ALCOR 920 a hard to beat laser source for two-photon imaging involving green fluorescent proteins (GCaMP-based calcium imaging in particular) or 2P photostimulation using blue light-sensitive opsins (e.g., Chr2). On top of that, it readily compensates for the group delay dispersion introduced by AO deflectors, hence SPARKS LASERS' ALCOR 920 is especially well suited and qualified by Femtonics to be designed-in the 3D acousto-optic (AO) microscopes, such as the FEMTO3D Atlas developed and solely provided by Femtonics. »András Fehér, Physicist, Application Optical Engineer, FEMTONICS (microscope manufacturer), Hungary
« We have found the ALCOR 920 FLeX with optical fibre delivery to be a great solution to the problem of finding a reliable hands-free source for GFP excitation. The system operated straight out the box with no adjustment and little set-up. It has a rapid start-up and an easy-to-use control interface. We have found the fibre delivery to be a really convenient method for integrating the laser with our microscope system and the adjustable built-in dispersion compensation came optimised for the installed fibre. In addition, the support from Spark Lasers and their UK representatives (Laser 2000) has been excellent. »Dr Gordon Robertson, Chief Technical Officer, PXYL Ltd, September 2021
