ALCOR XSight Ultra-compact femtosecond laser for biophotonics with adjustable power Please get in touch On Request

The ALCOR XSight produces high-average power with ultrashort femtosecond pulses (down to 100 fs) at high repetition rate (80 MHz standard, others optional) in an ultra-compact and robust format, offering fixed wavelength at 920 nm and/or 1064 nm. It is a fibre laser with a best-in-class quality and collimated beam providing high-stability.

ALCOR XSight benefits: 

  • Maximised output power

  • Reduces footprint on optical set-ups and within microscopes

  • Integrated prealigned AOM, not affecting pointing stability and polarisation

  • All electronically driven in one housing and one interface

  • Cost effective and maintenance free. 

The ALCOR XSight offers:

  • Ability to modulate power with a 1µs response time

  • Power control: set electronically through GUI or serial communication protocol (C language provided on USB hard drive)

  • Analog power modulation from 0% to 100%

  • Modulation by TTL signal (0 - 5V) which allows gating ON and OFF

  • >1.5 W average output power after AOM.


Integrating state of the art high-power full package amplifiers and pulse management, ALCOR offers remarkable pulse quality at high average power with no maintenance required.
