Application of fiber lasers in different industries
Fiber lasers are gradually replacingtraditional lasers in laser marking, laser welding, laser cutting and other
areas of dominant position.Today to explain the fiber laser in the field of
advantage.
Application of fiber laser marker in
industry
Industrial production requires high
reliability, small size, quiet and easy to control. Fiber laser with its
compact layout, light conversion to high, short preheating time, influence
factors, maintenance free and easy and small fiber or by optical lenses
composed of light guide system coupling strengths favored by people. Fiber
lasers are gradually replacing traditional lasers in laser marking, laser
welding, laser cutting and other areas of dominant position.
In the marking field, because of the high
beam quality and positioning precision of fiber laser, fiber marking system is
replacing Nd:YAG laser pulse marking system which is not obeyed by CO2 laser
and xenon lamp.In Europe and Japan, for the big range hold, only in Japan, the
monthly demand is higher than 100.According to IPG reported that, after the
German BMW Motor Company purchased their high-power fiber laser, used in the
door welding production line.
As the largest manufacturing country in the
world, the demand for optical fiber laser marking machines is very large, and
it is estimated that more than 2000 units will be needed every year.In the
laser welding and cutting with the development of music category, or even a few
million kilowatts kW fiber laser, fiber laser has also been used.
Application of fiber laser in sensing
Compared with other light source, fiber
laser is used as light source sensor has many advantages.First of all, fiber
laser has such advantages as high utilization, good tunability, compactness,
compactness, light weight, convenient maintenance and good beam quality.Second,
the fiber laser can be well coupled with the fiber, and is fully compatible
with the existing fiber optic devices, and can be tested with all fiber.
Now, fiber optic sensing based on tunable
narrow linewidth fiber lasers is one of the most popular applications in this
field.The spectral linewidth of the fiber laser is very narrow. It has a very
long correlation length and can modulate the frequency very quickly.The narrow
linewidth fiber laser has been applied to the diffuse sensing system to realize
ultra long interval and ultra high precision optical fiber sensing.Now, fiber
optic sensing based on tunable narrow linewidth fiber lasers is one of the most
popular applications in this field.China is expected to have more than 100
units of this kind of fiber laser every year.
Application of fiber laser in communication
Compared to other types of fiber laser, has
obvious advantages in compact layout, heat dissipation, beam quality, volume
and compatibility with the existing system, widely applied in the field of
communications
Rare earth doped fiber as the gain medium of
the mode-locked fiber laser can light pulse ultrashort high repetition rate,
pulse width for the occurrence of picosecond or femtosecond lasing wavelength,
and the optimal window falls in the optical fiber communication 1.55 M band, is
the ideal light source of optical communication system in the future.Now, the
mode-locked fiber laser with repetition frequency of 40 GHz and 10GHz has been
developed.Once this communication network is deployed, the demand for this
paradigm laser will be enormous.
Now, the mostly used for clinical laser
argon ion laser, CO2 laser and YAG laser beam, but usually they are not high
quality, has a very large volume of water cooling system, need to be huge, and
the placement and maintenance is very difficult, which exactly is the fiber
laser can be replenished.Because the water molecule has a absorption peak at 2
m, the 2 m fiber laser is used as a surgical operation, which can achieve rapid
hemostasis and avoid the damage to the human body caused by surgery.
