What Is The Differences Between Gaussian Laser And Flat-top Laser in Pulse Laser Area

1.The influence of energy distribution of laser cleaning

The green-red dotted area is the processing window
The peak part of Gaussian light is extremely easy to damage the substrate
If you need to peel off the substrate-for example to remove black rust,gaussian light is preferred

If you do not want to damage the substrate-such as mold cleaning,flat-top light is preferred

Gaussian laser	Flat-top laser

2.Laser parameter comparison

The single reason for the effect of conventional lasers is low laser pulse energy and Gaussian beam energy distribution.

At present, the laser processing system used by most laser cleaning manufacturers is a Gaussian spot, and the energy distribution of the flat-top beam is more uniform, which is more suitable for fine processing such as laser cleaning and laser polishing.

Flat top beam---Evenly distributed energy;
The degree of substrate damage-no damage;
Optical fiber length---10m can be customized, large workpieces can be cleaned in a large area;
Single pulse energy---High, wide adjustable range, to meet different cleaning needs;
Focusing depth of focus-large, can be used for cleaning specialshaped parts;
Cleaning efficiencyhigh, suitable for batch cleaning
 

3.Scope of application
 

Flat top light: suitable for more applications
Aerospace field: cleaning before and after welding of engine parts; cleaning before and after welding of carrier rocket storage box; removing paint and releasing agent for composite materials; removing aircraft skins, etc.
Mold products: tire molds, packaging molds, injection molds, food molds, etc. in addition to carbon deposits.

3C industry: circuit board depainting; wafer cleaning;mobile phone case depainting; PVD coating fixture cleaning
New energy: lithium battery pole pieces and poles; Ushaped steel for battery packs; parts cleaning, etc.
In addition, it has a wide range of applications in the fields of navigation, shipbuilding, bridge maintenance and petrochemical industry.
