1. What is the internal structure of the BS3015D-1500W fiber laser?
In terms of the whole machinethe fiber laser is composed of three parts: optical, mechanical and electrical.
The components of light are the three blocks mentioned in my report:pump source resonant cavity and gain medium.
The pump source is a semiconductor laserthe resonant cavity is composed of a grating beam combinerand the gain medium is an active fiber.
2. What are the reasons for the high melting point
temperature of the internal cavity of the laser? How to reduce the temperature?
There are many reasons for the high melting point temperature of the internal cavity of the laser which is a very complicated process problem.
It may be caused by such factors as fiber matching,welding quality and pump absorption conversion.
For this kind of fiber matching,we will generally choose the same type of fiber laser try to
have the same core diameter, and at least the cladding diameteris closer so as to reduce
the welding matching loss.
There are also welding qualitythat isvarious welding parameter settings of our welding
machine can have many optimization areas and parameters can be optimized through size adjustment and other methods.
Another is the pump conversion rate.
In addition, if the overall heat dissipation design is betterbetter results can be achieved.
3. Why do two lasers of the same brand and model perform differently when cutting the same plate?
Cutting is a process and relatively complex.
The output characteristics of the fiber laser itself are also many.
Such factors as power and spectrum are different for each laser and these factors wil have a certain impact on cutting.
At the same time the cutting headnozzleplateetc.are also involved in the cutting
There are many comprehensive variables, so it is difficult to say that the cutting effects of the two lasers are identical
But now we are working hard to improve the overall tolerance of the laser
The tolerance of the cutting process has been improved.
In the face of various variablesrelatively consistent cutting effects can be achieved.It is still difficult to achieve complete consistency at present
