日本东北大学开发了一种治疗牙齿和皮肤用、通过2.94μm波长掺饵(Er)YAG激光的新医疗用光纤。利用银和树脂涂敷内径0.7 mm的中空玻璃纤维内侧,以提高反射率。
Tohoku University has developed a new medical optical fiber for the treatment of teeth and skin, passing Erbium-doped (YAG) laser at a wavelength of 2.94 μm. Silver and resin are used to coat the inside of hollow fiberglass with an inner diameter of 0.7 mm to improve the reflectivity.
