Er glass used for medical laser instrument

Erbium and ytterbium co-doped phosphate glass lasers have a broad application because of their excellent properties. The best laser crystal rod glass material for 1.54um laser is due to its eye-safe wavelength of 1540 nm and high transmission through the atmosphere. We have three kinds of Erbium-doped glasses for different use:

  • Erbium-doped yttrium aluminum garnet
  • Glass crystal rod
  • Ophthalmic glass laser
  • Q zar laser tag

The prospects of getting efficient laser generation from Er at 1centerdot54 μm with Nd and Yb co-dopants in an unclad glass rod. As for er glass laser machine, the laser targets and treats intensively for every column, but leaves the surrounding tissues intact. 

The first works concerning eye-safe generation in erbium glasses were presented in 1965. For these experiments, silicate glasses were used, but soon, phosphate glasses turned out to be much more efficient. 

At the General Physics Institute, Laser Materials and Technology Research Centre Russian Academy of Sciences in Moscow, under Professor Denker’s leadership, two new types of erbium glasses were developed. 

Medical Fractional Er glass laser was developed in about the 1970s. In the 21st century, medical Laser Erbium、Therapy, Medical Laser rods, and wrinkle and pigmentation removal were used in many ways to protect our health.
