They are using a unique fiber optic transmission technology. In 1995 Laserblast 2/641 718 patent was granted the production license. This patent covers a nanosecond pulse energy range of surface cleaning applications. This patent application and in many countries through, covering Europe (European Patent Number: 0,380,387) and the United States (U.S. Patent Number: 5,151,134). In June 1998, Laserblast French Group installed a robot manipulator, a transmitter and a set of laser industrial cast iron mold cleaning system to good effect. So far, QUANTEL-LASERBLAST has invested enormous human and material resources to develop to meet the needs of industrial cleaning products. The good appearance of green laser pointer make it fashionable and beautiful.
riliant family after repeated verification of the innovative parts as Quantel company's flagship product is Laserblast core of the system. (Such laser product development in 1991-1992, and 1993 target industrial applications ingenious products.) Quintiles LASER the BLAST Features: condenser chamber with ceramic diffuse reflector cavity design without magnesium oxide powder, so in addition to high stability and high efficiency characteristics of this technology another significant advantage is that it is safe to replace the flash condenser chamber offset. This will enable non-professionals to complete routine maintenance of the laser. The optical system uses a separate heat stable structure. The outstanding feature of this kind of green laser pointer lies in the following.
This eliminates the normal work in industrial production due to the impact of severe temperature changes of laser, to ensure that the laser equipment in industrial production. This design also ensures that the flash replacement, to prevent dust and other pollutants into the condenser chamber. Principle of Laser LASER BLAST principle: laser cleaning is based on the result of the high-intensity beam, short-pulse laser and the pollution layer interaction between the photophysical reaction. The laser cleaning process depends on the characteristics of the light pulses generated by Laserblast system: its physical principles can be summarized as follows. Laser emission beam was required to deal with pollutants in the surface layer absorbed. Large energy absorption of the rapid expansion of the plasma (highly ionized gas) of instability, and shock waves. Main functions of green laser pointer will be introduced with slide.
The shock wave that pollutants become debris was removed. The pulse width must be short enough to avoid heat accumulation to the surface to be processed damaged. Experience has shown that when there are oxides on the metal surface, the plasma generated on the metal surface. The plasma in the case of the energy density above the threshold, the threshold depends on the pollution layer or oxide layer was removed. Threshold effect in the case to ensure the safety of base material for effective cleaning is very important. Plasma appears there is a second threshold. If the energy density exceeds this threshold, then the base material will be destroyed. To ensure the safety of base material under the premise for effective cleaning, laser parameters must be adjusted depending on the circumstances, the light pulse energy density is strictly between the two threshold. The parameter of laser pointer is perfect.
