Neurosurgeons use lasers to treat brain tumors. It was found that the technology broke through the blood-brain barrier. This research result provides new treatment options for patients with these fatal diseases. The blood-brain barrier is a natural "safety system". It can prevent the poison in the blood from entering the brain, and at the same time, it cuts off potentially therapeutic drugs from entering the brain, such as chemotherapy. Said a professor of neurosurgery at Washington University in St. Louis. We were able to make the brain blood membrane barrier disintegrate about 4 weeks after laser pointer treatment.
So not only your tumor is killed. You are actually opening a skylight of opportunity. So that a variety of drugs and chemicals and various treatments can reach the affected area. Otherwise these treatments will not reach the affected area at all. Research on the application of laser beams in the treatment of brain tumors. It has now entered the so-called phase II clinical study, which is compared to early clinical trials. Treat a larger population. Determine whether the treatment is effective. To further determine the safety of the treatment. In 2009, the US Food and Drug Administration approved this laser technology. As a surgical method for treating brain tumors, the tool includes a small laser needle probe. This laser needle probe heats and completely kills tumor cells.Getting a green laser pen is unnatural, but it is often considered the most visible demonstration tool. The green DPSS laser converts the electric energy into 808nm infrared light, and then sends it to the neodymium crystal, which converts 50% of the electric energy into 1064nm infrared light. The 1064 nm beam is then sent to the KTP crystal, which converts 50% of the 1064 nm green light to 532 nm. There is a long process before I finally get it. First, you need to know what your goals are. If the application is a demonstration, a 10 to 100 MW green laser is sufficient. If it needs to be used for astronomy or outdoor survival, it is recommended to 30-500mw (the maximum astronomy shall not exceed 200MW, otherwise it is easy to cause pilot accidents). If you have to do a laser experiment, you can choose the wattage that best suits you and remember that there is no such thing as a 30000mw green laser pen.
