Heat handling has been often a challenge for high power fiber lasers when the output power grows abruptly. But this is no longer a matter of concern, there is far better solution not just capable of handling health proficiently but also offering a thong of advantages. And this is none other than cladding power stripper which has magical capacity to deal with the unwanted optical power.
So the methods of stripping the unwanted light got much attention recently, and the thermal effect is now given much emphasis. Cladding power stripper uses microchannel sink –one of the most promising high efficiency heat exchange technologies, which improves the efficiency of heat exchange by sinking heat in CPS.
CPS is a component of the system used to remove unwanted light and distribute the heat converted by it. It is perfect for a system that transmits signal light in the core which absorbs inner cladding and all pumping light.
The cooling technology is implemented at the time designing of cladding power stripper structure. Header shaped microchannel provides better flow velocity uniformity than the trapezoidal and the triangular headers.
The CPS works better within a certain temperature. The temperature should not be more than 60 ◦C because of colloidal macromolecule substances in fiber. The idea temperature for cladding power stripper is 50.9 ◦C. CPS with microchannel heat sinking is sufficient for 10 kW DCFLSs.
So advantages of cladding power stripper can be summed up as:
- it is ideal for 10 kW DCFLSs
- It can work within as high temperature as 60 ◦C
- It uses microchannel heat sink –one of the most efficient cooling technologies
However, the convective heat transfer coefficient depends on thermal conductivity and diameter of cooling liquid. For microchannel the diameter is 0.1–1 mm[8] , the convective heat transfer coefficient can be improved significantly. If convective heat transfer coefficient is replaced, the dissipated heat will increase, which means there will be more cooling.
To sum up
Given its super ability, along with other several benefits, to dispersing heat, CPS (cladding power striper) is hailed as the best for high power fiber lasers and a system that transmits signal light in the core where inner cladding and all pumping light. You can buy high quality cladding power stripper in China at the best price from a reputed dealer like DK Photonics, a leading name optical passive components.
