green laser pointer energy absorbed by the particle

Material on the absorption rate of ultraviolet wave excimer laser pulse width, and thus high power density. In addition to the excimer laser to conventional drilling, cutting, plan processing, but also directly use the mask method is generated on the workpiece pattern. Removed by laser irradiation, the material of photochemical ablation, whether drilling, cutting, or carved, are straight-walled sharp corners, no heat-affected zone. Processing of small size, the sub-micrometer accuracy depends on the mask, the efficiency depends on the laser power. The customer asks for more green laser pointer for tryout
The mask method there are masks and mask projection two of the workpiece surface, shown in Figure 4. The recent development in the field of micromachining laser cleaning and laser study of the gripping tool (tweezers). Laser cleaning is the removal of ultra-clean ultra-smooth surface contamination particles, the principle is, the explosive vaporization of the laser energy absorbed by the particle or surface or man-made cleaning medium (eg water) to remove particles from the surface. This method can be effectively used in the development of semiconductor devices, laser gyro. Laser tweezers for particles of organic material handling and fixed principles of a micrometers organic particles in the laser waist, be subject to a pair of very sub force (when the particles Negotiable 1μ m) or the refractive power (when the particles > 1μ m),. The result of visual inspection of green laser pointer is good.
YAG laser, the commodity devices power increased from 500W to 1000W. The laser cavity and compressed the divergence angle device, the laser beam divergence angle reduced to below 5 mrad, and improve the focusing power density, enhanced processing capacity. The daily use of green laser pointer will be the subject of the meeting.
In recent years, following several aspects of both the breakthrough of the laser output power and job stability, so that the laser processing technology has leapt to a new level. The laser from the structure to overcome the laser rod thermal deformation (thermal lens effect), it is the power (up to 2kW), beam divergence angle is small (close to the diffraction limit), high-quality laser output, improve the processing capacity can be ultra-deep processing, such as drilling depth up to 76mm cutting thickness of 40mm. Laser diode (LD-Laser Diode) pumped Nd: YAG laser the laser with the absorption bands consistent with the YAG spectrum laser diode-pumped Nd: YAG, greatly reducing the non-absorbed light energy conversion with heat. The leaders are doing study on the quality of green laser pointer . Rapid Prototyping is the laser technology and computer technology to combine a high-tech manufacturing technology, the main function is to quickly transform the three-dimensional data into the entity has great benefits.
