Lasers can be directed to light

My country attaches great importance to the development of flight-second pulse technology, with the establishment of the national laboratory for focused transient processes and the super-fast spectroscopy laboratory at the sian institute of optical precision machinery and the university of nakayama, respectively, to implement the 863 programme to follow up on the development of international flight-second technology. The beijing institute of physics, the changchun institute of physics, tianjin university, beijing industrial university, etc. Have also studied flight-second spectra and flight-second pulse lasers. The sian institute of optical precision machinery has made a titanium 152fs lock pulse, the shanghai institute of optical precision machinery has made a 452fs pulse magnifying the compressed pulse, and the shanghai institute of optical precision machinery has made a unique contribution to titanium precision and other solid laser materials. In general, however, our research on flight-second pulse lasers is still in the laboratory stage, and there is a significant gap between their practicalization and their application, which is clearly related to the country's overall industrial base and level of scientific research, and which is easily manufactured by the air-second pulse lasers themselves, but it is expensive to source and can be purchased by importing them, with only a few major institutes and universities, which significantly limits the development and application of flight-second pulses in the country, where research on flight-second pulse technology is only at the stage of tracking international developments, without excluding, of course, the possibility of leading or breaking a certain area. Our laser market is limited, but crystals such as bbo, lbo, which have been invented by fujian material structures, are well marketed internationally. This suggests that our flight-second pulse research should not be limited to the level of domestic application but should remain at the stage of tracking international development trends, as long as there are original technologies to compete internationally。
