【文章內(nèi)容簡介】 laser as an example, in Lowend module and stable operation of state, received only about 1000 W (at the technical standards available to lowend module 2500 W). Therefore, most have been put into production in the crossflow CO2 laser beam only a multimode, almost no development of lowend module and the ringlaser welding applications.3Laser poor stabilityIn the course of operation of equipment, often light path deviation circuit fault and other issues affecting the progress of production. After an investigation of the laser resonator stability of poor, vulnerable to the optical axis drift, caused spots and uneven distribution of energy laser beam from the optical center。 power use circuit board control, stability poor discharge system to produce a small gain.4Poor technical equipmentThe plexity of the cladding technology, laser equipment, most of the feeding by gravity, a shop powder or preferences powder。 unable to plex 3D shape of the feeding parts and repair.3． 項目實施內(nèi)容序號升級部位升級項目技術(shù)及功能特點描述1激光器光腔光腔采用“高可靠模塊化”結(jié)構(gòu)光腔模塊結(jié)構(gòu)包括：位置調(diào)整模塊、角度調(diào)整模塊、前腔模塊、后腔模塊、光軸監(jiān)測模塊。光腔調(diào)整簡單、可操作性強；降低光腔維護成本。2光腔采用“二折高效復(fù)合腔”機構(gòu) 該復(fù)合腔在不改變原光腔長度的前提下，增加腔內(nèi)諧振范圍，放電增益區(qū)進(jìn)行充分的激光振蕩，電光轉(zhuǎn)換效率達(dá)到18%以上。二折腔機構(gòu)相當(dāng)于光腔的長度增加一倍，考慮到放電增益區(qū)寬度限制。3激光器電源、電氣控制部分控制系統(tǒng)采用工控機控制。采用工控機作為激光器控制中心，對電流、氣壓、水流均采用高可靠性傳感器件，將采集到的信號輸入到工控機中，經(jīng)程序運算后，輸出到相應(yīng)控制繼電器或輸出相應(yīng)模擬量，同時對輸出信號進(jìn)行反饋檢測保證程序順利進(jìn)行，保證整個控制系統(tǒng)具有高的穩(wěn)定性及可靠性。4放電極采用多排針放電結(jié)構(gòu)采用多排放電針放電結(jié)構(gòu)，可以實現(xiàn)3排針或更多排放電結(jié)構(gòu)，增大增益區(qū)寬度；每個放電針均進(jìn)行微調(diào)處理，使放電系統(tǒng)更穩(wěn)定。5風(fēng)機電機驅(qū)動變頻控制風(fēng)機電機驅(qū)動采用變頻控制器，通過改變頻率來獲得不同的電機轉(zhuǎn)速，實現(xiàn)風(fēng)機由慢到快的平穩(wěn)提速過程，同時可以通過工控機實現(xiàn)風(fēng)機轉(zhuǎn)速的優(yōu)化調(diào)整。適當(dāng)?shù)奶岣哳l率，可增大風(fēng)機的轉(zhuǎn)速，獲得更高的激光輸出功率。3． Contents Of Project ImplementationNo.Upgrading siteUpgrade projectsTechnical and functional characteristics described1Laser cavityCavity of highly reliable modular structureCavity module structure, including: position adjustment module, angle adjustment module, the former chamber module, after the
