2000nm Laser(Medical)

Tm: YLF has a large emission cross section of nearly 2 μm, and the fluoride has moderate hardness and thermal conductivity and is commonly used as a laser substrate. Under the same pumping conditions, the thermal lensing effect of YLF is much weaker than that of YAP. therefore, Tm: YLF is also widely used in the medical field. The 2 μm laser has important applications in high-precision surgery, mainly because water molecules absorb light in this band, thus reducing its penetration into the body. The cutting accuracy is on the order of microns, resulting in minimal damage to the nearby area.

2000nm Tm YLF Laser for medical Application

Tm: YAG laser of 2μm has good prospects for application in the fields of LIDAR, laser ranging, and laser medicine. Compared with other lasers, the most significant advantage of Tm laser in medical treatment is that it can effectively promote tissue coagulation and vaporization and has a good hemostatic effect.

When the laser acts, most of the energy is first absorbed by the water, which is heated to expand rapidly. When the temperature rises to the boiling point of water, the surface tension formed by the vaporized bubbles exceeds the maximum tension of the tissue surface. The structure will be destroyed, and the ablation is immediately ejected from the tissue surface.
