| 摘 要： | 基于准相位匹配(QPM)技术,对周期性极化RbTiOAsO4(PPRTA)晶体的允许参量进行了理论分析和数值模拟,得到了在波长为1064 nm,Ⅰ类和Ⅱ类相位匹配条件下的允许波长分别为0.25 nm/cm,0.45 nm/cm,和允许温度分别为2.30℃/cm,17.14℃/cm。并获得了室温时的允许角度为3.12°/cm1/2。数值模拟结果表明,Ⅱ类相位匹配比Ⅰ类相位匹配更加适宜于倍频过程。

| Abstract: | The permitted parameters are theoretically investigated in type Ⅰ and type Ⅱ for periodically poled RbTiOAsO4 (PPRTA) crystal based on the quasi-phase matching (QPM) technology. When the type Ⅰ and type Ⅱ QPM PPRTA crystals pumped with 1064 nm, the acceptance wavelength bandwidths are 0.25 nm/cm and 0.45 nm/cm, the acceptance temperature bandwidths are 2.30 ℃/cm and 17.14 ℃/cm respectively, and the acceptance angular is 3.12°/cm1/2 at room temperature. The numerical simulation results indicated that type Ⅱ QPM technology is more suitable for second-harmonic-generation (SHG) than type Ⅰ. |
