1500nm Laser
Er 3+ /Yb 3+ co-doped phosphate glass emits a laser that is safe and easy to measure in the 1550 nm band, and this band also corresponds to the low-loss window of the fiber. Lasers made with this material have broad applications in optical communication, laser radar, laser ranging, and other aspects. Because the visual medium has a low transmittance to laser radiation of 1530~1560μm wavelength, and it is not easy to damage the retina, lasers made of this material can also be used in the medical field, and there have been reports of successful treatment of corneal diseases.
