The emergence of high power fiber lasers, and their
applications, is one of the most significant photonics breakthroughs in the
last decade. Fiber lasers consist of a long “fiber-optic active laser medium,”
pumped primarily by diode lasers directed into the fiber cladding.
They have CW outputs exceeding 10KW and can produce
output pulses as short as 10 picoseconds. Because the pump light from the diode
lasers lies in the absorption bands of the fiber laser active medium, the
conversion of input electrical power to output laser power is highly efficient
(30-40% efficiency, as compared to gas and solid lasers with efficiencies below
1%).
Average output powers from fiber lasers can reach as
high as 10KW. Fiber lasers can operate in the CW mode or in various pulse
modes; even picosecond pulses.
Because fiber lasers are smaller, more efficient,
lighter weight, less costly, and their output beams are easier to manipulate
than CO2 or Nd:YAG lasers, they are becoming the laser of choice for
many materials processing applications, such as welding, drilling, cutting and
etching of metals, plastics, ceramics, glass etc.

OP-TEC has developed two instructional modules on fundamentals
and applications of fiber lasers. They can be previewed at http://www.op-tec.org/photonicstechnologies.
We have also identified inexpensive equipment and designed labs to accompany
the modules.

fiber lasers are suitable for a variety of applications, such as telecom, industrial, scientific, medical, and LIDAR.
Nowadays, Fiber Laser are more advanced those are equipped with up to 100W of power. And fiber lasers possess numerous optional features, such as polarization maintaining, SLM, OEM format, and plug & play turnkey systems.
