In order to solve the facial or unsightly moles in other parts of the body, the traditional way of energy-saving, frozen moles, in recent years, the effect is more convenient and exact to the number of laser point mole. Compared with the traditional way, green laser pointer point nevus has obvious effect on removing nevus, and less…
Laser technology as a core of industrial manufacturing driving force, itself is constantly moving forward. To sum up, the laser is toward the “faster, higher, better, shorter” in the four directions. Higher: the power of the laser is getting higher and higher, the average power has more than 10 million watts. In 2013, the first…
Recently, scientists said in a paper published before, try ultra fast laser writing in silicon, femtosecond laser in the structure to bulk silicon processing problem has been a breakthrough, the extreme NA pulse can achieve sufficient ionization breaking of chemical bonds in silicon laser allowed, leads to the change of permanent silicon materials structure. Since…
