Fiber laser is pumped with
special high power multimode diodes via cladding surrounding
as single mode core. Life of this individual multimode diode
is quite long corresponding to conventional diode pump solid-state
Fiber laser is virtually
Free compared to other conventional laser, as
it doesn’t have mirror to be aligned and almost no optical
components, which could havw been damaged.
Fiber laser is pumped by
multiple identical diodes all feeding same gain medium, whereas
DPSSL is pumped by a single diode bar. In the unlikely event
of failure of any single pump diode in the fiber laser, the
laser continues to work with slightly lower specification.
In case of DPSSL, the total laser fails if diode stops working.
The out put beam quality
is exceptionally good with diffraction of m2 < 1.5 to 2.0
depending on the power requirement. This leads to better performance
and Improves power to work ratio.
|Fiber laser system is air cooled rather water-cooled
multi-channel diode bars.
It operates at very low electicity
consumption and it normally cooled by just air-cooling, which
leads to significantly lower operating cost.
The total power generation
and build in fiber laser occurs along a long length of fiber.
Thus heat is dispersed over a large surface area unlike DPSSL
where heat is normally localized, leading to failure.
Thanks to multiple diode
pumping and moduler design, fiber laser laser has very little
chances of failure. Hence diode replacement cost relative
to DPSSL is significantly low.
The biggest benefit of fiber
laser is that the Gain Medium is fiber & delivery is also
through the fiber. This leads to less chances of failure at
coupling point between gain medium and delivery when extended
to the workplace.
|The efficiency of fiber is up to 20%
