In the “Single Pulse mode,” the femtosecond laser generates a single pulse at the nominal PulsePicker frequency of the laser. This pulse carries the entire energy output. This mode is commonly used and straightforward, ideal for applications that require a single powerful pulse.
You can find some applications where this option can be used:
Precision Micro-Machining: For precise material removal, micromachining, and surface structuring, where a single high-energy pulse is sufficient.
Medical Procedures: In laser-based medical treatments, especially surgical procedures requiring precise and controlled energy delivery in a single burst.
Ultrafast Spectroscopy: For scientific research, precisely timed single pulses are essential for various spectroscopic experiments.
Burst Mode (Standard):
In the “Burst mode,” the femtosecond laser amplifies several pulses at the PulsePicker frequency. The total pulse energy is distributed among these pulses, dividing the energy between them. This mode is versatile and provides flexibility in energy distribution.
Material Processing: For applications like micro-drilling, cutting, and surface texturing, distributing energy across multiple pulses ensures uniform and controlled material removal.
Optical Imaging: In microscopy and imaging, distributing energy in bursts can minimize photodamage while capturing detailed images.
Scientific Research: Burst mode suits experiments requiring moderate energy pulses for synchronization, pump-probe techniques, and time-resolved studies.
Super Burst Mode:
The “Super Burst mode” is a non-standard mode. Here, the PulsePicker frequency is adjusted to maintain the total pulse energy in the first pulse. This mode concentrates the maximal energy in the initial pulse, while others have lower energy. Due to its ability to maintain maximum energy in the first pulse, the total energy of the super burst mode exceeds that of a simple burst mode.
This option is particularly applicated in Non-Standard Experiments: Research scenarios requiring an extremely high-energy initial pulse, even at the expense of lower energy in subsequent pulses.
In summary, these three options cater to diverse femtosecond laser applications by manipulating burst energy distribution. The “Single Burst mode” offers a powerful single pulse, suitable for various precision applications. The “Burst mode” divides energy across multiple pulses for versatile material processing and imaging. While non-standard, the “Super Burst mode” can address specific experimental needs at the risk of uneven energy distribution.
Select the mode according to application requirements and desired energy distribution in bursts, considering energy distribution precision for optimal outcomes in your specific case.
