Femtosecond Laser

The Axinite series lasers utilize a dependable fiber seed source in conjunction with amplifiers to produce high-power infrared femtosecond laser output. The seed laser pulse is amplified using a high-gain fiber amplifier, decreasing its pulse duration to 500fs while ensuring M^2<1.3 beam quality. In addition, the laser offers multiple control functions for stable long-term operation.

Feature:
Compact, integrated design
Self-made seed source with automatic change point via SESAM
Burst pulse editing function
Pulse on demand (PSO function)
Ethernet communication, independent GUI, and remote diagnosis
Real-time data detection and recording function

Advantages and Applications of Femtosecond Laser

Femtosecond lasers produce a concentrated burst of energy in a very brief period. This results in ultrafast, high-intensity laser output that has various applications. In comparison, continuous wave lasers are limited in their peak powers when compared to these short laser pulses. Femtosecond lasers have the potential to be used in new ways due to their ability to deliver ultrafast, high-intensity output.

In industrial applications where ultrashort pulse laser pulses are used, such as material processing, ultrashort pulses are used to minimize thermal damage to materials. The laser pulses act as localized heat sources that quickly evaporate material at their focal spot without dispersing heat into surrounding areas.

Femtosecond lasers have an advantage for new applications due to their extremely short pulse duration. This makes it possible to observe and modify ultrashort processes found in biology or chemistry.
