  1. The analyses given in this paper to quasi - three - level for 946 nm laser are complete. the relation between 946 nm laser transmission and optimal crystal length has been derived from the rate equations describing the population inversion and the photon density in the laser cavity in the steady - state case. the minimal claims to coating have been given on the base of contrasting 946 nm transmission with 1064 nm transmission in the condition of different cavity losses and how the pump beam radius in the laser crystal and optimal crystal length affect the laser threshold and output power of 946 nm laser has been given as well

    對產生946nm譜線的三能級結構給出了較為完整的分析,利用諧振腔處于穩態時的速率方程,導出了三能級nd : yag946nm起振時,透射損耗與最佳晶體的關系,在與1064nm透射損耗相比較的礎上,給出了不同的腔損耗情況下的最低鍍膜要求,並且給出了閾值、輸出功率和最佳晶體及泵斑大小的關系,這為設計室溫下高效運轉的946nm器的提供了理論礎,這種分析方法對研究此類低增益,三能級或三能級系統輸出特性有借鑒意義。
  2. In this paper, firstly, monolithic materials cosb3 and bi2te3 were prepared by sparkle plasma sintering ( sps ) respectively, and at the same time the microstructure of cosb3 and bi2te3 were studied by sem ; the seebeck coefficients and electrical conductivities of monolithic materials were measured by standard - four - probe method ( ulvac zem - 700 ) in a he atmosphere simultaneously, and their thermal conductivities were investigated by laser flash method ( tc - 7000 ) in vacuum. secondly, the junction temperature of graded bi2te3 / cosb3 thermoelectric materials was optimized based on the thermoelectric transport properties of monolithic materials, also when graded materials were used in the temperature difference ranging from 300k to 800k, the length ratio of monolithic materials cosb3 and bi2te3 were optimized in theory. thirdly, graded bi2te3 / cosb3 thermoelectric materials were prepared by two - step sps sintering, and the relationship between its average seebeck coefficients and temperature were calculated by theory mo del

    均質材料cosb _ 3和bi _ 2te _ 3的電導率和seebeck系數採用標四端子法于he氣氛下在zem - 1上同時進行測量;熱導率採用微擾法( tc - 7000 )于真空狀態下進行測量;其次,在對均質材料cosb _ 3和bi _ 2te _ 3熱電傳輸特性研究的礎上,對結構梯bi _ 2te _ 3 cosb _ 3熱電材料的界面溫進行了優化;為了使結構梯bi _ 2te _ 3 cosb _ 3熱電材料在300k至800k的溫范圍內具有最佳的熱電性能,本研究同時對梯結構熱電材料當中均質材料cosb _ 3和bi _ 2te _ 3材料的進行了優化設計;第三,通過兩步放電等離子燒結的方法制備出了結構梯bi _ 2te _ 3 cosb _ 3熱電材料;採用理論計算的方法研究了梯結構熱電材料平均seebeck系數和溫的關系;同時為了驗證設計的結果,本論文對結構梯bi _ 2te _ 3 cosb _ 3熱電材料的開路輸出電壓和熱端溫之間的關系及梯材料在300k至800k的溫范圍內使用時的功率輸出進行了相應的研究。
