【摘要】：鑒于目前561nm激光器噪聲較大,影響其實用性,提出一種高穩(wěn)定性低噪聲的561nm黃光激光器。利用Nd妣YAG晶體得到1 123nm基頻光,通過LBO晶體腔內倍頻得到561nm輸出。理論分析了1 112nm、1 116nm與1 123nm波長的閾值泵浦功率,提出1 123nm的單波長振蕩條件,確定諧振腔鍍膜要求。根據理論計算,設計了合理的諧振腔膜系,通過抑制1 112nm與1 116nm譜線在諧振腔內的振蕩實現(xiàn)1 123nm譜線的單波長振蕩。在泵浦功率為5W時,實現(xiàn)了561nm激光單波長輸出,輸出功率達到107mW,功率不穩(wěn)定性達到0.7%,噪聲為1.2%。
[Abstract]:In view of the high noise of 561nm laser, which affects its practicability, a high stability and low noise 561nm yellow laser is proposed. The fundamental frequency light of 1123nm is obtained by using ND YAG crystal. The output of 561nm is obtained by intracavity doubling of LBO crystal. The threshold pump power of 11116nm and 1123nm wavelength is theoretically analyzed, and the single wavelength oscillation condition of 1123nm is proposed to determine the coating requirements of the resonator. A reasonable resonator film system is designed to realize the single wavelength oscillation of 1123nm by suppressing the oscillation of 1112nm and 1116nm. The single wavelength output of 561nm laser is realized when the pump power is 5W. The output power is 107 MW, the power instability is 0.7 and the noise is 1.2.
