Product description
Beam Profile ALCOR Spark Lasers

The ALCOR fs fiber laser from our supplier Spark has been specially developed for multiphoton microscopy and provides the optimal specifications for green fluorescent proteins (GFP) and calcium indicators such as GCaMP with an excitation wavelength of 920 nm. For red-shifted indicators (RCaMP, dtTomato, MCherry), the ALCOR is also available with 1064 nm.
For all users who use both green and red flourophors, the ALCOR is also available as a dual-head with two laser heads and one controller.
With ultra-short pulse durations of < 100 fs and 80 MHz repetition rate, the ALCOR delivers an average power of up to 5 watts (5 W version) which allows high penetration depths or greatly accelerates the scan time by multiplexing.
Due to the fiber laser technology, the ALCOR is also more space-saving and requires less maintenance than conventionally used Titan:Sapphire lasers. This makes it the perfect solution for all users who do not need to cover a wide wavelength range with their 2-photon microscope and are looking for a simple and reliable solution.

The optional ALCOR XSight extension allows you to continuously control the power via an acousto-optic modulator (AOM), and the Flexsight option makes it very easy to integrate the laser into your setup with fiber coupling.
