中文拼音 [lízixībèng]
離子吸泵
英文
ion sorption pump-
Recent electronic means of pumping using low temperature sorption techniques and getter-ion pumps have been introduced.
現在已經採用了低溫吸附技術和吸氣離子泵的近代電子抽氣設備。Getter-ion pumps decrease chamber pressure by chemical reaction of residual gases with an evaporated metal.
吸氣離子泵通過剩餘氣體與蒸發的金屬之間的化學反應減少了內腔的壓力。Phosphate glass is an ideal material for high erbium - doped. erbium ion has large emission section in phosphate glass, however, it has small absorb section for 980nm pump light, which can be settled via doped yb3 +
雖然鉺離子在磷酸鹽玻璃中具有較大的發射截面，但對波長為980nm泵浦光來說，其吸收截面較小，可用鐿離子與之摻雜來補充這一不足。The first ytterbium - doped yttrium - aluminum garnet ( yb : yag ) laser action was reported back in 1965 using a lamp - pumped rod at 77 k. because of poor spectral overlap of the lamp with the the trivalent ytterbium ion ( yb3 + ) absorption band, the efficiency was very low. lamp - pumped nd : yag lasers fared better due to the multiple pump bands of neodymium
但yb3 +離子的泵浦吸收帶與閃光燈光譜匹配很差，導致其激光效率很低;而nd : yag的激活離子（ nd3 + ）有多個泵浦帶與閃光燈光譜匹配，較好適應了燈泵浦的需要，長期占據了固體激光器的主導地位。Ytterbium ( yb ) - doped silica fibers have a broad - gain bandwidth ( 850 ~ 1050nm ), excellent power conversion efficiency, and a broad - absorption bandwidth ( 900 ~ 1200nm ). their ability to provide amplification over the very broad wavelength range from ~ 975nm to ~ 1200nm is expected to generate increasing interest in the near future. they offer an almost ideal gain medium for the fiber lasers and fiber amplifiers that work at the wavelength around 1 m
摻鐿石英光纖具有幾個方面的優點，如能級結構簡單，與摻er3 + 、 nd3 +等稀土離子的光纖相比，不存在對泵浦光或信號光的激發態吸收（ esa ） ，可以有更高的摻雜濃度;有較寬的吸收光譜（ 850 ~ 1050nm ） ，可以利用多種泵浦光源來設計泵浦方案;輻射光譜寬（ 900 ~ 1200nm ） ，激光輸出波長可以有很寬的可調諧范圍。Zmd series of self - suction magnetic drive pumps are widely applied in industries such as petrochemical industry, non - ferrous metal smelt, pesticide, acid and alkali manufacturing, papermaking, pickling technology, rare earth dialysis, electroplating and electronics etc., and it is the most updated magnetic drive pump currently
Zmd自吸式磁力泵廣泛適用於石油化工、有色金屬冶金、農藥、制酸制堿、造紙、酸洗工藝、稀土分離、電鍍、電子等行業，是目前磁力泵品種中最新穎的產品。The analyzing model was established, and a novel inner - cladding structure of dcf with higher performance was designed. integrated by the absorption and emission characteristics of rare - earth - ions in dcf and the ld ' s pumping principle with its relative references, the - academic model of high power dcf laser with f - p cavity was based, by using methods of numerical analysis, the high power dcf laser was simulation with good results and consistency
結合稀土離子的吸收及發射特性及二極體泵浦固體激光原理，應用相關的理論建立了高功率f - p腔型光纖激光器的理論分析模型，利用matlab 、 mathcad ， origin等軟體，採用數值計算及分析方法，結合具體參量數值對實驗進行了模擬分析，並研究了不同特性參量對激光器性能的影響。分享友人
