2940nm laser

2940nm Laser

The Er: YAG laser is a solid-state pulsed laser with a wavelength of 2.94um, and its wavelength is exactly at the highest absorption peak of water. Its absorption efficiency is 200 times that of the 2.1μm Ho: YAG laser and 10,000 times that of the 1.06μm Nd: YAG laser. Based on this feature, it can be used for precise cutting and soft tissue ablation with less thermal diffusion and mechanical damage to adjacent tissues. When the krypton laser pulse acts on the skin, the energy is quickly absorbed by the tissue, causing the superficial skin to heat up rapidly, resulting in instantaneous vaporization and separation, and the tissue is precisely sloughed off. Er: YAG laser has achievable high-precision cutting and can be used for medical laser microscopic treatment in dermatology, stomatology, cardiology, ophthalmology, etc.

2100nm laser(Ho YAG)

2100nm Laser

The wavelength of Ho: YAG laser is 2100nm. The absorption of 2100nm laser by water is about 25 cm-1, which is 25 times more than the absorption of Nd: YAG laser . Therefore, the Ho:YAG laser penetrates soft and hard tissues shallowly, because of high surgical precision and unique coagulation effect that limits the area of damage. The Ho laser can be delivered in a low OH-based quartz fiber, and can work efficiently in both gas and liquid environments.The Ho laser endoscopically treats a variety of intracavitary diseases.

2000nm Tm YLF Laser for medical Application

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.

671nm laser

671nm Laser

Holography can be divided into two processes of recording and reproduction. The recording process is to superimpose the reference light and reflected light on the object onto the holographic plate to create interference fringes. After processing the plate in a dark environment, the interference pattern on the sensor plate is replicated by diffraction to be exactly the same as the original object. Compared with ordinary photography, holography can not only record the amplitude of the light field of the subject, but also the relative phase of the reflected light waves. It is widely used in holographic microscope, holographic anti-counterfeiting, data storage, deformation measurement and holographic interferometer.
