5W FEMTOSECOND LASER FOR MULTI-PHOTON MICROSCOPY!

May 11 , 2021

THE NEW ALCOR 1064NM 5W FEMTOSECOND LASER FOR MULTI-PHOTON MICROSCOPY!

The ALCOR laser series from SPARK Lasers just received a nice power boost! This series, offered in a dual 920nm and 1064nm wavelength configuration up to 2W, or a single wavelength configuration with up to 4W at 920nm (highest power 920nm fs laser on the market), now expands it's offerings to 5W of power at 1064nm! The new ALCOR 1064-5W is the ONLY femtosecond laser offering such a high average power with a fixed wavelength at 1064 nm, and it has the very same low-SWaP form factor as the rest of the ALCOR series.

Alcor - GDD PrecompensationSuperior Performance!

 

This 5W 1064nm version provides excellent pulse characteristics, offering >62nJ of pulse energy at a fixed repetition rate of 80MHz (40MHz also available), with a pulse duration of <130fs, for a peak pulse power of >480kW! The extremely high peak power of the ALCOR 1064-5W provides better brightness and contrast for your 2-photon microscopy application. This version comes standard with GDD precompensation from 0 down to -30,000fs^2 (others optional), conveniently tunable from the laser's user interface. With negative GDD precompensation applied in the laser head, pulse duration is kept the same from laser output to beam excitation on the cells/tissues, despite any optics that would induce dispersion on the pulse. The ALCOR series also provides a 'clean pulse' by minimizing side lobes to avoid any thermal effect around the treated cell. SPARK Lasers specifically designed and developed the ALCOR 1064-5W for larger surface imaging for multi-photon microscopy, allowing a higher level of brilliance and contrast for two-photon excitation of calcium indicators such as GCaMP of other red opsins (RCaMP).

 

 

 

The ALCOR 1064-5W can be optionally equipped with the XSight, fully-integrated electronics module, for power adjustments and modulation. By itself, this laser has no power modulation, and can only operate in alignment mode or full power mode, with no intermediate power levels. Adding the optional XSight module allows for precise control with fine power adjustment by percentage of total power, fast gating with TTL signal (<1µs response time), fast power modulation with analog signal (<1µs response time), and power adjustment of the modulated signal, all through either the GUI or serial communication protocol.
