Semiconductor lasers, commonly known as laser diodes, are called semiconductor lasers because they use semiconductor materials as working substances. The semiconductor laser is composed of a fiber-...

Laser medical treatment has been applied in many clinical departments, which not only improves the treatment effect, but also reduces the risk of complications and improves the quality of life of p...

With the rapid development of laser technology, the application of laser in the medical field has received more and more attention. Due to its advantages of non-contact, high precision, small damag...

The hazards caused by radiation have deterministic effects and random effects. Radiation-induced radiation-induced cataracts and other types of radiation diseases are deterministic effects, which w...

In recent years, due to the improvement of X-ray equipment, the amount of X-ray exposure has been significantly reduced, and the possibility of radiation damage has become smaller and smaller. But ...

In recent years, lead glass has been used in more and more places, mainly for the manufacture of optical instruments, art instruments, etc. Lead glass is also known as medical X-ray anti-radiation ...

All kinds of radioactive rays cannot be sensed by human senses, but the harm they cause is very huge. Therefore, all kinds of laboratories and hospitals will be equipped with special radiation prot...

Radiation equipment has greatly facilitated the physical examination and treatment of patients. In addition to patients, doctors need to better protect themselves from radiation hazards during reas...

We are not unfamiliar with laser processing , but you can often hear nanosecond laser, picosecond laser, femtosecond laser, etc, can you distinguish it? Let's figure out the time unit conversion fi...

Although there are a variety of lasers , they are generated by excitation and stimulated radiation, so the basic composition of the laser is fixed, by the working substance (that is, the working me...

According to the analysis of the principle of laser generation , it is known that the laser is under the action of the "excitation source", the number of high-level electrons of the atom increases,...
