LASER WELDING PLASTIC TECHNOLOGY
The commonly used laser welding form is called laser penetration welding. It is firstly to force the two plastic parts to be welded to be together through pressure and then locate a laser beam in short wave infrared region onto the position to be welded. The laser beam, after going through the upper-layer transparent material, will be absorbed by the lower layer. The laser energy, after being absorbed, will be transformed into heat energy. Since two layers of materials are forced together, the heat energy will conduct to transparent layer from absorbing layer, which would make the two layers of materials melt and connected. At the same time, the internal pressure occurs because of the material’s thermal expansion. So the joint effort of the internal and external pressure can make sure that the two parts are firmly welded. For the product whose lower-layer material does not absorb laser, absorbent needs to be added to the lower layer.

LASER LIFT OFF TECHNOLOGY FOR MICRO LED
The display structure of the micro led is a miniaturized led array. At present, the size of a single micro led chip can be fewer than 10 μ m, which is 1% of the size of the conventional led. Each micro led can be regarded as a pixel, each pixel can achieve address control, separate drive and self-luminous. Structurally, micro led is a p-n junction contact diode that is formed by p-type GaN material and n-type GaN material while both the two materials are in close contact. When a forward voltage is applied on both sides of the p-n junction, that is, the positive voltage is applied on the p-type GaN side, and the negative voltage is applied on the n-type GaN side, the carriers on both sides of the p-n junction can easily move between each other. Then the radiative recombination of electron-holes occurs to produce light emission. The micro led array connects the positive and negative electrodes of each micro led through a vertical staggered positive and negative grid electrode and lights up the micro led to display the image by scanning through the sequence of the electrode lines.

A MOPA FIBER LASER MARKING TESTING ON PE MATERIAL
We used five main parameters to adjust the marking effect on the black plastic(PE) with MOPA fiber laser marker. They are “speed”, “frequency”, “power”, “fill distance” and “mode”. One of the advantage of our machine is that it has multiple mode(Pulse width)—8 in total, compared to other fiber laser source with only one mode. In this report, we test four parameters and marked the letter “A” on the material. To test, we change one specific parameter with 8 different values while keeping the other four parameters unchanged.
