df laser
解釋
氟化氘激光器-
With the development of infrared tunable opo, its application is more and more wide. lt is possible for us to estimate the quality of resonant mirrors in laser with high energy and to improve the output energy of laser, by measuring the reflectivity of resonant mirrors of coil and df laser by cavity - ring - down which use output wave of opo as the laser source, instead of coil and df laser with high price and huge space
用opo紅外輸出激光作為光腔衰蕩的光源代替價格昂貴、體積龐大的氧碘和氟化氖激光器，對其諧振腔鏡的高反射率進行測量，以達到對高功率激光器腔鏡高反膜質量的評價，為改進膜系設計、鍍膜工藝優化和提高激光器的輸出能量提供理論依據。 -
The dependence of cw df / hf cl performance on the flow - field parameters in f & d2 / h2 reacting zone, which act as criterion to nozzles design, has been inversely educed on the light of original formula of gain coefficient, output power and laser efficiency
從增益系數、輸出功率和激光效率的基本模型公式出發，逆推得到了df hf化學激光器性能對光腔中f和d 。川。反應區流場參數的依賴關系。 -
4. we design the experiment of acvity - ring - down to measure reflectivity of the mirrors of coil and df laser with high reflectivity respectively at wavelength 1. 315 m and 3. 8 m, and perform the experiment of measuring reflectivity of coil laser resonant mirrors. the experimental result is discussed in detail
