The basic structure and the fundamental principle of semiconductor saturable absorption mirrors ( sesam ) that are used for passive mode - locking solid - state lasers are introduced 摘要介紹了半導體可飽和吸收鏡( sesam )的基本結(jié)構(gòu)及使用半導體可飽和吸收鏡被動鎖模固態(tài)激光器的基本原理。
We use the laser output ( 320 nm , 200 fs ) of optical parametric amplifier ( opa ) in < wp = 5 > an active passive mode - locked femtosecond ti - sapphire laser operating at a repetition rate of 1khz as a exciting resource to develop optically pumped stimulated emission of zno thin films . when rectangular stripe laser irradiates thin films , optical resonant cavity is naturally formed between two nanocrystallites along with the rectangular laser stripe and planar weveguide confines the light scattering 利用飛秒激光器作為光泵浦激發(fā)光源,研究了氧化鋅薄膜的光泵浦受激發(fā)射,當條形光斑輻照薄膜樣品時,將沿著光斑條由氧化鋅納米晶面自然地形成光學諧振腔,由于平面介質(zhì)波導結(jié)構(gòu)限制光散射,所以成功地觀測到二氧化硅襯底上的納米氧化鋅( zno )薄膜的紫外受激發(fā)射。
The actively and passive mode - locked fiber ring laser and two types of photonic switching , slalom ( semiconductor laser amplifier loop mirror ) and uni ( ultrafast nonlinear interferometer ) were developed . this thesis presented the principle and the requirements for the optical of frequency - shift sampling module under common conditions 研制了作為光取樣脈沖源的主動鎖模和被動鎖模光纖激光器;半導體光放大器環(huán)鏡及超高速非線性干涉儀的光子開關,并進行了頻差法光取樣、異步光取樣及基于時分光取樣的光子模數(shù)轉(zhuǎn)換的實驗研究。
