How to choose a laser cutting machine?
In fact, the green Laser pointer consists of an optical cavity, a gain medium and a pump source. The wavelength is determined by the energy level structure of the atoms, molecules or ions in the gain material. At present, all developed countries have prioritized crystals, nonlinear optical devices and applications, and incorporated them into their high-tech development plans as an indispensable strategic measure, giving them great attention and strong support.

According to quantum theory, any observation and interference in the macro will quickly change the quantum state and cause it to collapse. In this way, the information obtained by the thief due to interference is destroyed instead of the original data. Therefore, quantum communication can realize free and secure connections. Optical fiber has also been widely used in medicine. Existing laser technology has always had a shortcoming, and can only emit light of a single wavelength or a narrow frequency band. How to expand the frequency of the green laser to form a cohesive, super-continuous, ultra-wideband white laser covering the ultraviolet, visible and infrared bands is still an unrealized dream of mankind. This is a global scientific and technological problem. Endoscopes such as gastroscopes allow the doctor to see the patient. Fiber optic sensing technology and systems are also commonly used in industry and used in various manufacturing and processing processes.
