Thirdly , the structure of ejecting in the base region with unmatched pressure ( sebup ) is introduced . the sebup can produce a high average pressure in the laser chamber , while the low pressure which is needed by the active medium is set up locally too . the steady flowfields and the unsteady flowfields in start - up course of sebup are also simulated with cfd method , and the experiment of sebup is made . the
在本文最后,根据以上研究的结果,提出了“基区非匹配压力引射结构” 。这一结构的特点是,它能够在提高光学谐振腔的平均静压力的同时,建立出有利于出光的局部低压区。本文用cfd技术对它的稳态和启动的瞬态流场进行了模拟,并实施了实验。
