中文摘要
近年來光電技術發展迅速,因而帶動半導體雷射激發固態雷射的發展。半導體雷射激發固態雷射可結合半導體雷射體積輕巧、高效能及低價格的特性,以及固態雷射高品質輸出模態的優點,且轉換效率高、壽命長、結構簡單,因此被廣泛地應用於電子、通信和醫療各業。本研究採用小尺寸之晶體光纖作為雷射增益介質,再於晶體光纖兩端鍍上光學薄膜做成共振腔,可大幅縮小雷射增益介質之體積,降低成本,簡化固態雷射整體架構,同時提高散熱效率。
我們使用雷射加熱基座生長(laser heated pedestal growth) 法生長晶體光纖,此法不但可輕易生長出直徑極小之單晶,且生長速度快、耗能低、控制容易,既經濟又迅速,且無坩堝污染之問題。利用此方法我們已生長出23~285 mm之高品質Nd:YAG晶體光纖,以適當的材質包覆,加以研磨、拋光、鍍膜即可製成Nd:YAG晶體光纖雷射。我們並進一步地量測晶體光纖內Nd3+離子濃度,發現在其橫截面上Nd3+離子濃度有內高外低的漸進式分佈,而使得光在此晶體光纖傳輸過程中有自聚焦的現象,再針對此現象進行分析。
目前,我們已成功研製出半導體雷射激發的Nd:YAG晶體光纖雷射,斜率效率為28.9%,就我們所知此為目前最高之紀錄,最高輸出功率達80mW。未來將改進晶體光纖的散熱方式、晶體光纖包覆的製作及晶體光纖表面之光學鍍膜,以提升轉換效率及輸出功率。


Abstract
The rapid developments in optical and electronic technologies have accelerated developments of solid state laser technology. The diode-pumped solid state laser has the merits of the diode laser, such as compactness, low cost, and the merits of the solid state laser, such as high laser quality, high conversion efficiency, long lifetime, and simple structure. So, it has been applied in electronics, communication and medicine widely. In this work, the crystal fiber was used as the laser gain medium, and coated with optical thin film at its end facets as the laser cavity to be able to reduce largely the volume of solid-state laser, and improve the heat dissipation.
We used laser heated pedestal growth (LHPG) method to grow crystal fiber, which can grow with small diameters at very fast rate and accurate control. High quality Nd:YAG crystal fibers with diameter of 23~285 mm were grown. After cladding, grinding, polishing, and coating, we successfully fabricated the Nd:YAG crystal fiber laser. We discovered that the gradient concentration of Nd ions distributed over the cross section of crystal fiber is helpful in focusing lights.
We have successfully implemented diode-laser pumped Nd:YAG crystal fiber laser with a slope efficiency of 28.9%. It is the best result up to this time as we know. The maximum output power is 80 mW. In the future, we shall improve the cooling system, the cladding, and coating to further increase the conversion efficiency and output power.
