ALCOR Compact High-Power Femtosecond Laser
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 fibre-based design offers high stability, high reliability without any maintenance, making it the perfect industrial laser for scientific applications.
