mJ Q-Switched Cladding-Pumped Yb-Doped Fiber Ring Laser
Description
In the field of rare-earth-doped silica fiber applications, there has been a growing interest in high-power cladding-pumped fiber lasers using Er and Yb ions as active dopants. Such lasers can be operated in the pulsed mode by using the Q-switching technique and are capable of generating pulses with multi-millijoule energies, peak powers of the order of 10 kW and durations of the order of 100 ns. These characteristics, as well as high spatial beam quality and compact uncooled laser arrangement make fiber lasers an attractive source for typical high-power pulsed applications such as, for instance, range finding, nonlinear frequency conversion or material processing that until recently have been dominated by conventional solid-state lasers.

Frequently Asked Questions
Q-switching is achieved by using an acousto-optical switch (AOS).
This laser is suitable for high-power pulsed applications such as range finding, nonlinear frequency conversion or material processing that until recently have been dominated by conventional solid-state lasers.
The pulse shape and duration depend on the laser parameters, AOS switching times, pulse repetition rate, and cavity length.
It is a type of fiber laser that uses Er and Yb ions as active dopants and can generate pulses with multi-millijoule energies, peak powers of the order of 10 kW and durations of the order of 100 ns.
Fiber lasers offer high spatial beam quality and compact uncooled laser arrangement, making them an attractive source for high-power pulsed applications.
