Innovative Femtosecond Lasers for Multiphoton Applications

Fiber-based femtosecond lasers are rapidly emerging as a leading solution for multiphoton applications, thanks to their compact, alignment-free design, user-friendly operation, and exceptional robustness.

By achieving sub-50 femtosecond pulse durations, these lasers unlock new possibilities—particularly in applications where peak power plays a critical role in enhancing performance and image quality.

In this webinar, we explore:

• The fundamental physics behind ultrashort femtosecond laser pulses
• The advantages of operating in the sub-50 fs regime
• The remarkable two-photon efficiencies and high peak powers these lasers deliver
• Their impact on advancing multiphoton microscopy, optogenetics, multiphoton polymerization, and terahertz generation

We’ll also highlight recent applications that demonstrate the benefits of shorter pulse durations in pushing the boundaries of research and innovation.
