Scientists at Yale University have developed a new multifunctional laser pointer imaging system that can observe the structure of biological tissues as well as dynamic activities such as pulse and blood cell movement.
According to a related introduction from Yale University, the new laser has played an important role in the imaging system. In one mode, the laser can image structural information by reducing the number of speckles, which usually appear randomly to reduce imaging quality. In the past traditional high-speed imaging light source, speckle often appeared.
However, on the other hand, speckles still carry additional information, which is helpful for biological imaging. For example, by analyzing the speckle pattern, it is possible to image blood cells moving in a living tissue.
The new laser system can image in the above two modes, has a compact structure, and can provide continuous emission wavelengths. The system can be switched in different modes and can achieve high output power thanks to semiconductor components.
Therefore, the femtosecond green laser pointer is an important tool for studying high-order nonlinear and multiphoton processes in atomic and molecular systems. The energy density corresponding to the femtosecond laser can only exist in a nuclear explosion. Femtosecond intense light can be used to generate coherent X-rays and other extremely short-wavelength light, which can be used for controlled nuclear fusion research.
