A year ago, people directly detected gravitational waves for the first time. laser pointer experts from the Planck Institute for Gravity Physics (Albert Einstein Institute AEI), and from the University of Leibniz Hannover, and from Hannover Laser Center (LZH) played a role in this discovery The main tsa laser pointer carry on function is because the core instruments in the US laser interference gravitational wave observatory used by them have ultra-precision laser technology to detect weak gravitational wave signals.
Now, researchers at the Einstein Institute have proposed two new technologies that can not only further improve the sensitivity of future gravitational wave detectors. The Max Planck Society now also strengthens the development of the laser system of the third-generation gravitational wave detector. The Einstein Institute cooperates with the Hanover Laser Center and plans to invest 3.75 million euros in research funds in the next five years to develop the new laser Zentrum. The Hanover Research Center received more than 3.75 million euros in research funds over the next five years. Research on new lasers and methods to improve their stability.
We have made important breakthroughs. The professor said that he is the leader of the laser development group of the Einstein Institute. "Our work is to further study another new type of laser beam used in the interference gravitational wave detector. In addition, we have shown how to improve the power stability, that is, the stability of the high-power laser used in the detector. This is an important step in the study of gravitational waves in astronomy in the future," the results of this study were published in the famous scientific magazine "Optical Express" and received the attention of editors.
The research team demonstrated how to obtain a more uniform high-power green laser pointer beam, creating the so-called LG33 mode. Now that he has completed his master's thesis, the team is trying to apply these laser beams to future gravitational wave detectors.
The first step into the detector is a device called a predictive mode cleaner, which optimizes the beam profile and reduces beam jitter. The team found that the new beam is compatible with the predictive cleaning mode currently used. The researchers also showed how to solve this problem. They have developed a new pre-cleaning mode, which is compatible with the laser mode. The design of the next generation of gravitational wave detectors has not yet been completed. Therefore, we are testing different types of lasers, discovering as many options as possible, and implementing new gravitational wave detectors as much as possible. With the laser beam, we have now made a big step forward.
