According the temperature distribution of the high power laser diode array , we design a high efficient water cooler to accelerate the conduction of heat with the circular water in the cooler in order to disperse the heat in the active region of a laser , so we can keep a constant operational temperature . by doing those and solving such problems , we can master the technology of gaining the high duty - cycle high power laser diode array , including the material growth , the making of a laser bar 通過對該項目進行研究,解決高占空比大功率半導體激光器陣列材料生長、管芯制作、器件制作等工藝難點,掌握高占空比大功率半導體激光器陣列的制作關(guān)鍵技術(shù),將激光器工作的脈沖占空比提高到20 ,以適應(yīng)泵浦nd : yag固體激光器的要求。
The binary optical elements are small , light , easy to be copied and able to realize multi - purpose integrated , especially suits for the beam shaping of laser diode array , thus make us choose it for realizing our system . because single module gaussian beam can be decomposed in a pair of vertical directions , we transform each pair of vertical beams outputted by bars separately , this can make our design easy to achieve 可實現(xiàn)多功能集成等特點,特別適用于半導體激光器列陣的光束整形,因此我們選用二元光學器件來實現(xiàn)耦合系統(tǒng)?利用半導體激光器輸出的基模高斯光束可分離變量的特點,我們對面陣中各吧的兩個相互垂直方向上的光束分別進行整形變換,這樣整形器件可以設(shè)計成一維結(jié)構(gòu),便于實現(xiàn)
In recent years , high power laser diode array has been widely applied in many application fields such as pump solid laser , material processing and laser medical exposure , however , because of the bad performance of its output beam , which affects its direct application , thus make it a hot view which people pay much attention on how to transform the beam of the high efficient laser diode array , institutions internal and abroad have been doing much research on the problem 近年來,大功率半導體激光器列陣被廣泛用于泵浦固體激光器?材料加工及激光醫(yī)療等應(yīng)用領(lǐng)域中,但由于其輸出光束的質(zhì)量不好,影響了它的直接應(yīng)用,因此大功率半導體激光器列陣的光束整形成了人們關(guān)注的一個熱點問題,國內(nèi)外的研究機構(gòu)對此進行了大量的研究
