Magnetron Sputtering High Purity Erbium Er: Communication Optics, Medical Devices, and Sharp Optics

Erbium is an important rare earth element with numerous application fields. This article will focus on the Advanced Institute of Science and TechnologyMagnetron sputtering deposition of high-purity erbium ErDiscuss the preparation and application of erbium doped fiber amplifiers, medical laser materials, and rare earth upconversion laser materials, and introduce their outstanding applications.

Erbium doped fiber amplifier - breaking through the optical loss limitation of communication systems

Erbium doped fiber amplifier is an important fiber optic communication device, whose core is to dope erbium into ordinary quartz fiber and combine it with 980 nanometer or 1480 nanometer semiconductor lasers to amplify 1550nm optical signals. Specifically, doping erbium at tens to hundreds of ppm can compensate for optical signal loss. This application can significantly improve the efficiency and distance of optical signal transmission, and is an important component of modern communication systems.

Medical laser materials - a powerful tool for precision cutting and surgical treatment

Erbium laser, as a medical laser material, has unique characteristics, especially in terms of wavelength, water molecule absorption, and energy utilization. The wavelength of erbium laser is 2940nm, which is strongly absorbed by water molecules in human tissue, so it only requires small energy to produce significant effects. This makes erbium laser highly suitable for medical procedures such as fine cutting, grinding, and removal of soft tissues. Cataract is a common eye disease, and erbium laser is widely used in cataract extraction surgery. Due to the fact that cataracts are mainly composed of water, erbium laser has low energy and is easily absorbed by water, making it a promising surgical method for cataract extraction. In addition, erbium laser therapy devices have opened up more possibilities for applications in the field of laser surgery.

Rare earth upconversion laser materials - a breakthrough in multiphoton upconversion luminescent materials

Erbium can also be used as an activating ion for rare earth upconversion laser materials, and has been applied in both single crystal and glass materials. Erbium doped yttrium aluminate (YAP: Er3) crystals and Er3 doped ZBLAN fluoride (ZrF4-BaF2-LaF3-AlF3-NaF) glass fibers have been put into practical use. Especially BaYF5: Yb3, Er3 can convert infrared radiation into visible light, and this multi photon upconversion luminescent material has been successfully applied in devices such as night vision goggles. The application of erbium in the field of rare earth upconversion provides important reference and support for the manufacturing of optical devices and the development of high-performance optical sensors.
