Applications of femtosecond laser systems
Modern fiber laser technology allows for detecting a chemical transformation inside a cell live. Additionally, it promotes the production of microchips by printing paths in a thin layer. The latest femtosecond laser system makes all these developments real to achieve.
Distinction of laser beam sources
Numerous laser beam sources are distinguished. Different laser systems have their own characteristics and fields of application. The novel fiber laser system emits ultrashort laser beam pulses, femtosecond ones. “This is the scale on which, for example, intracellular chemical reactions take place.”
Detection and material processing
These reactions can be identified by capturing an image using the new laser technology. The femtosecond laser beam source enables very accurate removal of materials from different surfaces without damaging them. The scientists claim that this fiber laser is too accurate.
Comparison with conventional fiber lasers
Certain applications require nanosecond laser beam pulses (they last longer). Conventional fiber lasers can’t draw paths of accurately planned depths in ultra-thin materials, compared to novel laser systems. Strong laser beam energy located in a small area leads to melting the materials.
The novel fiber laser system operates firmly and gently. It is prone to mechanical disruption since the laser system is compact and portable. Fiber lasers have significantly helped the team to develop the system. The operating principle of fiber laser systems is based on an optical fiber enclosed in a ring.
Pulse propagation and frequency control
The laser beam pulse passes inside the fiber without any mechanical disturbances. It is possible to touch, move, and shake the optical fiber not influencing the stability of the fiber laser. Also, this laser system offers a particular frequency at the output that makes the laser unique.
Standard laser systems use laser beam frequencies that are dependent on the length of the fiber optic loop in which the pulse passes. The solution is to reduce the circumference of the ring. Thus, scientists can control, change, and even duplicate the basic laser beam frequency.
