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 laser (DPSSL).

Fiber laser is virtually Maintenance Free compared to other conventional laser, as it doesn’t have mirror to be aligned and almost no optical components, which could have 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.

It operates at very low electricity 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 has very little chances of failure. Hence diode replacement cost relative to DPSSL is very 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.
