dc.description.abstract | 本篇論文以三大部分構成:準相位匹配與光參振盪器原理的介紹、光參振盪器晶體及光參振盪藍光產生器晶體之設計,以及光參振盪器系統架設與藍光產生器腔內倍頻實驗。
理論的部分,由簡入繁地介紹了非線性頻率轉換、準相位匹配、與基本的光參振盪器理論。接著在晶體週期設計的部分中,利用鉭酸鋰晶體色散的性質,計算所需之準相位匹配週期性極化反轉結構的週期大小。設計結果為:傳統532nm泵浦光參振盪器晶體極化反轉週期為7.76微米;自倍頻光參振盪藍光產生器晶體極化反轉週期為7.90微米,而級聯倍頻光參振盪藍光產生器晶體極化反轉週期分別為7.76微米與4.99微米。 在光學測量的部分,利用奈秒(~20ns)532nm綠光雷射進行光學泵浦實驗,使用晶體均未鍍膜。首先,測量二維周期性極化反轉結構藍光倍頻晶體之特性,並以理論計算驗證。再來,利用所設計之晶體架設一套奈秒光參振盪器系統,並設計分別共振於930nm與1260nm之兩種光學共振腔,測量此光參振盪器信號光之出光特性:對於930nm共振腔,可提供896nm~1032nm之雷射波長輸出,共振閥值和輸出功率斜線效率(Slope Efficiency)分別為6.0MW/cm2及22.8%;對於1260nm共振腔,可提供1098nm~1310nm之雷射波長輸出,共振閥值和輸出功率斜線效率分別為4.4MW/cm2及13.9%。對於級聯倍頻光參振盪藍光產生器,效能測試獲得單邊輸出之轉換效率達16.9%,轉換效率波長頻寬6.1nm;對於自倍頻光參振盪藍光器,效能測試獲得單邊輸出之轉換效率可達4.8%,轉換效率波長頻寬1.3nm。 | zh_TW |
dc.description.abstract | This thesis is organized into three parts : (a) a theory of quasi-phase matching and quasi-phase matched optical parametric oscillator(QPM OPO), (b) a design of one-dimensional periodically poled congruent grown LiTaO3 (1D-PPCLT) for constructing a 532nm laser pumped optical parametric oscillator (OPO) and the optical parametric blue light generators by two methods, (c) an implementation of two-dimensional second harmonic generation(2D SHG) experiment, a quasi-phase matched optical parametric oscillator system and two types of optical parametric blue light generators.
First, the theory of quasi-phase matching and optical parametric oscillation will be introduced in the second chapter. In the second part, the designed periods of periodically poled lithium tantalate will be introduced. The period for 532nm nano-second laser pumped optical parametric oscillator is 7.76micro-meter, the period of the self-doubling optical parametric blue light generator is 7.90micro-meter, and the period of the cascade optical parametric blue light generator is 7.76micro-meter and 4.99micro-meter. We finally implemented two types of singly resonant oscillators (SRO) at the wavelength of 930nm and 1260nm respectively. The output spectrum of the 930nm SRO ranges from 896nm to 1032nm, with a lasing threshold of 6.0MW/cm2 and slope efficiency of 22.8%. The output spectrum of the 1260nm SRO ranges from 1098nm to 1310nm, with a lasing threshold of 4.4MW/cm2 and slope efficiency of 13.9%. As for the optical parametric blue light generators, the cascading laser has 16.9% conversion efficiency for one side output coupling and 6.1nm acceptance bandwidth, and the self-doubling case has 4.8% conversion efficiency for one side output coupling and 1.3nm acceptance bandwidth. | en |
