Solid laser crystal ER: YAG
Tours Co., Ltd.
About This Product
It is a YAG crystal that adds an elvium to oscillate the 1,645 to 2,940 nm bands. It is mainly used as a media for 2,940nm medical care by adding 50%high concentration ER.
Since this wavelength band is easily absorbed by water, it has the advantage of less impact on the human body. 2,940nm is used for visual medicine such as corneal transplantation and glaucoma surgery, as well as skin and dental care.
■ Crystal manufacturing
Laser crystal manufacturing technology is improving year by year, and it can be produced up to 99.999%purity and up to φ50 mm. The uniformity of the ER concentration, the grains inside the crystal, the bubbles, and the glitter are disappearing. The surface accuracy is also the standard of S/D: 10/5, RA <0.4nm.
■ mass production
You can secure the quantity to be mounted on various medical laser products. It can be issued with the quality proof required during mass production.
It can also be purchased from one for research and development such as prototypes.
■ Basic wave 1,600Nm For optical communication ER: YAG laser component
The 1,600 nm is safe for the eyes of a human, and the transparency in the atmosphere is high, so it is useful as an infrared light of light inspection materials.
■ Basic wave 2,940Nm for dental and visual medicine ND: YAG laser component
ER: Speaking of yag, it is already used as a laser treatment as a medical institution as a solid pulse laser in the 2,940 nm (2.94um) band. This wavelength is absorbed for water, and its efficiency is 2,100 nm, HO: YAG, 10,000 times of 1,064 nm, nd; yag.
This property is good, with good heat diffusion, almost no laser damage to biological tissue, and can be accurately removed by soft tissue. Dental care includes tooth decay treatment, stomatitis treatment, and peripheral gingiva. It is used for skin treatment to remove moles, stains, and repair acne. Detailed explanations are to the doctor who is using it.
