The dissertation focuses on the yb3 + - doped double clad fiber laser. the research works in detail are shown as follows : 1. with the phase - mask method, we make a fiber bragg grating in a few - mode fiber whose cut wavelength is greater than 1060nm
本論文圍繞著摻yb3 +雙包層光纖激光器進行研究工作，報告了得到的科研成果，包括以下的內容: 1 .在截止波長高於1060nm的少量模光纖中用相位掩模法寫入布拉格光纖光柵，製作的布拉格光柵具有幾個透射峰。The patent covers the use of a computer - designed diffraction grating, a type of hologram that takes a single beam and breaks it up into an array of beams, each one of which forms an optical trap for particles of micron or nanometer dimensions
此專利涵蓋了電腦設計的繞射光柵，以及可將單一光束分散成陣列光束的雷射全像術，其中每道光束都會形成光阱，可捕捉微米或奈米大小的粒子。And when observers take a spectrum of the galaxy, the diffraction grating of the spectrograph disperses the light over a large area on the detector, rendering the signal even fainter at each wavelength
而當觀測者擷取星系光譜時，光譜儀的繞射光柵會把光分散到偵測器上一個很大的?圍，導致每個波長上的訊號更加微弱。
