This optional function available on Tangor 100, Satsuma, Satsuma X and Tangor 300 augments precision and addresses the inherent challenges of natural burst decline due to elevated gain on initial pulses.
In this study, we look closely at how Femtoburst® works, how it fits with femtosecond lasers, and how it improves precision in different uses.

Femtoburst® is a technical solution meticulously engineered to redefine burst shaping. Its primary purpose is to enable users to exert fine-tuned control over burst output, a crucial factor in applications reliant on precise energy distribution and timing.

When left uncontrolled, a burst’s energy weakens because of stronger initial pulses. This can lead to non-optimal outcomes, especially when precise timing and energy distribution are critical.

The Spectrum of Shaping: Customizing Burst Characteristics

The power of Femtoburst® lies in its versatility, offering a spectrum of shaping possibilities. Imagine a decreasing burst, where each successive pulse carries slightly reduced energy, ensuring a gradual and controlled energy distribution. This contrasts with a flat burst, where each pulse maintains consistent energy, which is ideal for applications demanding uniform energy delivery. Alternatively, consider an increasing burst, where each pulse’s energy escalates, aligning with applications requiring energy augmentation. Femtoburst® is not just a function; it’s a technical toolkit enabling users to sculpt burst energy profiles precisely.
