• Brighter images with Clean Pulse technology
• Fully turn-key with integrated AOM and GDD
• No noise-stress for animals thanks to fan-free passive cooling
• Compact laser design saving valuable table space
• Low cost of ownership using robust & reliable fiber-laser technology
In 2-photon microscopy, peak-power is brightness! If you care for the best image brightness, you need short pulses, high power, and most importantly a clean temporal pulse shape.
With TOPTICAs unique Clean-Pulse Technology, more than sufficient output power, and shortest pulses, the FemtoFiber ultra 920 features the highest relative peak power and enables unmatched brightness in 2-photon microscopy without unwanted heating of the sample.
Turn-key and intuitive operation, fully-integrated GDD and AOM make the system extremely user-friendly and allow you to focus on your research!
Without the need for regular maintenance or alignment TOPTICAs robust & reliable fiber laser technology significantly reduces the cost of ownership of your lasersystems. In addition, our quiet & compact laser design minimizes noise-stress to the animals while at the same time saving valuable table space.
The FemtoFiber ultra 920 is ideally suited for the two-photon excitation of common fluorophores like GFP, eGFP, Eosin, GCaMP, CFP, Calcein or Venus.
Center wavelength 920 nm Pulse duration < 100 fs Average output power > 1.5 W Repetition rate 80 MHz Motorized dispersion precompensation (GDD) -40000 .. +1000 fs² Integrated power control (AOM, optional) > 1 MHz AOM modulation bandwidth Power in main pulse > 98% (typ.)
