中文摘要
2 微米波段紅外雷射有許多在可見光所不具有的特點和可延伸的特殊用途。目前已有相當多應用包括氣體感測、醫療手術、能量傳輸、高增益放大器、紅外雷達、環境感測、焊接、生醫應用,等。
由於稀土元素中銩元素之良好的量子轉換效率與交叉弛豫現象,使其擁有較低的雷射閥值,摻銩光纖擁有1700奈米到2100奈米約略400奈米的操作波長,正好位於所謂眼睛安全範圍,也由於作為其泵補光源的793奈米雷射二極體取得容易,使其近年來成為良好應用於2微米雷射波段之新星。
本研究旨在製作國內首批單模摻銩光纖,以Nufern公司生產之單模摻銩光纖SM-TSF-9/125為比較樣品,截至今日已成功製造出多批不同摻雜濃度之單模摻銩光纖,並以在2 微米波長為高反射率之布拉格光柵光纖作為雷射共振腔結構,產生2微米雷射,量測自製摻銩光纖與比較摻銩光纖其2微米雷射效率,以此為基準,藉以調整其製程參數。
2 微米雷射應用方面,嘗試以2微米雷射作用於多元醇法生長奈米銀線,並以CO2雷射及Nd:YAG雷射比較其異同;也在聚甲基丙烯酸甲酯燒結方面進行嘗試。
Abstract
2 micron laser has certain characteristics and applications that visible lasers cannot provide as good, such as gas sensing, surgery, free-space transmission, high-gain amplifiers, IR-LiDAR, hazard prevention and rescue, cutting and jointing in manufacture, biomedical application, etc.
It is well known that rare-earth ions can be incorporated into single mode silica fiber, which can then form the basis of efficient fiber lasers. Thulium has emission peaks located at eye-safe wavelengths that spanning 400 nm, ranging from 1700 to 2100 nm. Out of the cross relaxation property such that it could has low lasing threshold by pumping with 793nm laser diodes which is available semiconductor laser diode. Thulium is one of the best candidate for an 2 μm fiber laser material.
The purpose of this study is to develop in-house technology for 2 micron Thulium-doped laser fiber within the specification of Nufern’s SM-TSF-9/12. Until now, we have successfully manufactured different doping concentration of thulium doped fibers, we choice fiber Bragg gratings as the cavity mirrors to generate 2μm fiber lasers, and measure its slope efficiency to adjust the manufacture parameter.
In term of 2 micron laser applications, we using 2 micron laser as the energy source with Polyol process which is a method related to the growth of silver nanowires and make a comparison between 2 micron laser, CO2 laser and Nd:YAG laser. We also have a try on Poly(methyl methacrylate) sintering.
