    20世紀80年代，人們意識到雙光子上轉換材料也許是一個新的選擇。
  5. The relaxation oscillation in solid - state laser with relaxation oscillation pumping is studied theoretically by the rate equation. the undulation of the laser photon density contains relaxation oscillation frequency itself and that of pumping. when those two frequencies are close, the oscillation will be resonated

  6. Full quanta theory was used in analysis the working principle of laser, educed the photon states of single pattern radiate in two energy - step system, and simulated the establishment of laser mode and statistical distribute of photon. according to elf consistent equations of rlg ; build the simulated program with labwindows / cvi and do some simulation experiments, the result of simulation matched the theory perfect perfectly and conform to the experiments, the locked - in and pattern competition coursed the periodic light intensity

    在激光陀螺自洽場方程組的基礎上，運用labwindows / cvi軟體建立了靈活方便的激光陀螺模擬平臺，並進行模擬試驗，模擬試驗結果與理論分析很好的相符合，且能夠較好地說明陀螺試驗現象，即在閉鎖閾值附近，由於閉鎖效應和模競爭相互影響，使得激光腔中兩行波相互關聯，光強差隨時間呈周期性變化。
  7. The control system includes two modules, one named the input module which acquires data digitally, and the other, named the output module, controls the emission of the laser, the gating function of the single photon counting module ( spcm ) and the synchronization of the input and output modules. each of them uses a complex programmable logic device ( cpld ) as the core component, and is devided into three parts : the hardware circuit, the programming logic circuit and the software

    該控制系統主要包括控制單光子發射、單光子探測器、數據採集接收系統的輸出系統和數據採集系統兩個模塊，它們都採用復雜可編程邏輯器件cpld作為核心功能晶元，由硬體電路設計、晶元編程和高級軟體編程三部分組成。
  8. Practical implementations of quantum key distribution systems use attenuated laser pulses as the signal source rather than single photons. the channels used to transmit are lossy. on the basis of above two points, a combining eavesdropping strategy of intercept - resend and beam - splitting is discussed in terms of eavesdropper ' s technology requirement and detection efficiency and dark count of single - photon counter
