Alcor

COMPACT HIGH-POWER FEMTOSECOND LASER

780, 920, 1040 and 1064 nm / < 100 fs / Up to 5 W

Spark Lasers’ ALCOR is specifically designed for two-photon excitation. It offers clean femtosecond pulses with the highest guaranteed peak power on the market, in an unprecedented compact format and with fixed wavelengths at 780, 920, 1040 and 1064 nm.

The compact laser head of ALCOR incorporates the widest range of computer controlled GDD precompensation on the market and, optionally, a fully aligned and turn-key AOM for fast power modulation and power adjustment. ALCOR can also be coupled to an optical fiber to deliver femtosecond pulses as close as possible to samples. ALCOR offers air cooling and ease of integration with the possibility to install the laser head in any orientation. ALCOR’s innovative fiber-based design offers high stability, high reliability without any maintenance, making it the perfect industrial laser for scientific applications.

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.

« 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. »
