The rare earth ions in LiNbO3 waveguide in determinate lattice bit with certain spectral characteristics, which can increase the emission cross section in the peak wavelength through reducing non-uniform widened, and then it can have a better pumping source and gain efficiency. Yb3+ was mixed as the sensitizing agent in the crystals to improve the up-conversion luminous efficiency of Ho:LiNbO3 crystals, because the absorption peak of Yb3+ and emission line of the commercial InGaAs diode laser have the same wavelength (980 nm), and it has only two energy level and has no up-conversion energy loss, the up-conversion luminous efficiency can be increased hundreds of times , therefore the Yb3+ has become the most effective sensitizing agent in the study of up-conversion. |

The rare earth ions in LiNbO3 waveguide in determinate lattice bit with certain spectral characteristics, which can increase the emission cross section in the peak wavelength through reducing non-uniform widened, and then it can have a better pumping source and gain efficiency. LiNbO3導(dǎo)波管中的稀土離子，通過(guò)光譜特性確定晶格，通過(guò)減小非均勻加寬，增加峰值波長(zhǎng)發(fā)射截面，從而獲得更好的泵源和更高的效率。 Yb3+ was mixed as the sensitizing agent in the crystals to improve the up-conversion luminous efficiency of Ho:LiNbO3 crystals, because the absorption peak of Yb3+ and emission line of the commercial InGaAs diode laser have the same wavelength (980 nm), and it has only two energy level and has no up-conversion energy loss, the up-conversion luminous efficiency can be increased hundreds of times , therefore the Yb3+ has become the most effective sensitizing agent in the study of up-conversion. Yb3+作為敏化劑，被添加到了晶體中，從而提高Ho:LiNbO3晶體的上轉(zhuǎn)換發(fā)光效率。 因?yàn)閅b3+吸收峰與商用銦鎵砷半導(dǎo)體激光的發(fā)射譜線具有相同的波長(zhǎng)（980 nm），并且只有兩個(gè)能級(jí)，也不會(huì)有上變頻能量損失，所以其（ Yb3+）上轉(zhuǎn)換發(fā)光效率可以提高幾百倍，因此，Yb3+已成為上轉(zhuǎn)化率研究中最有效率的敏化劑。 |
