ALCOR was released in 2018 and has continuously been improved to provide the highest standard of performances and reliability. Amongst these evolutions are the availability for innovative options such as fiber delivery and Multibeam. Version 9 of ALCOR 920 has been released in 2024 with the aim to provide remarkable two-photon imaging characteristics on every microscopy experiments.
Multiphoton microscopy requires high laser peak power to achieve high image brightness. In laser technology, high peak power is provided by the combination of high pulse energy, short pulse duration and clean pulses. Two-photon fluorescence increases quadratically with average power: for instance, an average power of 2 W will produce 4 times more fluorescence than 1 W. A laser offering the combination of higher power and shorter pulse duration is highly suitable to cover the increasingly challenging experiments in Neuroscience.
Spark Lasers introduced HPC® Technology (High Pulse Contrast) in 2022 to provide maximum peak power and achieve optimal image brightness in two-photon microscopy systems. HPC® exploits fiber laser technologies to clean and shorten pulses while increasing average power. This way, ultimate peak power with remarkable average power can be produced efficiently and in a compact fiber laser.
HPC® Technology is incorporated in ALCOR 920 to offer 1.5 W or 2.5 W average power with clean pulses of < 100 fs in duration ensuring the best performance on the market for two-photon microscopy.
