Pyroelectric photodetectors have continuously been an attractive candidate due to their
noncryogenic and easy-to-fabricate specifics. Because the detectivity or resolution of the …

We report the experimental determination of the ordinary and extraordinary refractive index
of 8 mol% Mg-doped congruent lithium tantalate (MCLT). Refractive index measurements …

We examine theoretically under what conditions mirrorless optical parametric oscillation can
be obtained in PPLN and PPLT. We take into account the damage threshold, idler …

We report both linear and nonlinear optical properties of a ferroelectric thin film of
polycrystalline BiFeO_3 deposited on a quartz substrate. The linear refraction index and …

A new method for changing the volume concentration of hydrogen in congruent LiTaO 3
(lithium tantalate, LT) crystals has been studied. It has been established that pre-treatment of …

In this paper, we present a theoretical model that describes the performance of a specific
oven configuration used to actively control the effect of thermal dephasing on the output …

We study thermal effects in high-power single-pass second-harmonic generation (SP-SHG)
of continuous-wave (cw) green radiation in MgO: sPPLT and describe optimization of critical …

摘要对基于周期极化钽酸锂(PPLT) 晶体的光参变振荡器(OPO) 技术进行了理论分析和实验研究
, 通过三波混频耦合波方程组, 计算了PPLT OPO 的波长调谐曲线. 分别研究了信号光单谐振 …

薄膜材料在现代科技中应用广泛, 其折射率是光学薄膜设计中的重要参量.
首先简要介绍了折射率色散基本理论, 其后着重分析了Cauchy 色散公式, Sellmeier 公式 …

We present a theoretical model that describes a multisegment oven configuration to
compensate for the Gouy phase shift in the tight focusing regime. The model is provided to …
