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. Now, Lastek and TOPTICA are offering Australian and New Zealand customers the opportunity to trial a FemtoFiber ultra obligation-free, in your facility.
Features:
• 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
With more than sufficient output power, shortest pulses, and our unique Clean-Pulse Technology, the TOPTICA 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 dispersion compensation to ensure shortest pulses at the sample and built-in power control make the system extremely user-friendly and allow you to focus on your research! The FemtoFiber ultra 920 at an output wavelength of 920 nm is ideally suited for the two-photon excitation of common fluorophores like GFP, eGFP, Eosin, GCaMP, CFP, Calcein or Venus.
Contact Jessica Mackintosh at Lastek today to schedule a trial in your facility.
Trials are taking place during the second half of 2025. They include all installation and training.
