Nei iyo fiber laser yekumaka muchina isina kunyatsomira?
1. Nzvimbo yelaser yakavharwa uye danda rekubuda rinopfuura nepagirazi remunda kana galvanometer. Pane zvikanganiso;
2. Panogona kuve nekukuvadzwa kune lens, izvo zvinokonzeresa kusawirirana kwelaser simba kana laser beam yaburitswa.
3. Kana iyo laser field mirror, galvanometer, uye fixture zvisina kunyatsogadziriswa, chikamu chechiedza chinenge chakavharwa. Mushure mekutarisa negirazi remunda, nzvimbo yechiedza pane frequency kaviri firimu haizove yakatenderera, zvichikonzera kusaenzana kwemhedzisiro.
Sei iyo fiber laser yekumaka muchina isina mhedzisiro yekumaka?
1. Shandisa offset focus kudhirowa zvinhu neimwe nzira: Lenzi imwe neimwe ine kudzika kwayo kwemunda. Kana iyo yakatarisa isiri iyo, mhedzisiro yekudhirowa haizove yakafanana.
2. Iyo kamuri inoiswa munzvimbo yakatwasuka, saka galvanometer, girazi remunda uye tafura yebasa hazvina kufanana, izvo zvichaita kuti urefu hwedanda huve hwakasiyana mushure mekubuda, zvichikonzera mhedzisiro isingabatsiri.
3. Thermal lens exposure: Kana iyo laser inopfuura nepakati ye optical lens (refraction, reflection), iyo lens inopisa uye inoshandura zvishoma. Iyi deformation inoita kuti iyo laser inotarisisa iwedzere uye kureba kwekutarisa kuve kupfupika. Kana muchina wacho wakagadziriswa uye chinhambwe chekutarisa chichigadziriswa, mushure mekunge laser yavhurwa kwechinguva, kusimba kweiyo laser simba kunochinja zvichienderana nechimiro cheiyo thermal lens yechinhu, zvichikonzera kusiri-chiratidzo mhedzisiro.
,
4. Pamusana pemamiriro ehupfumi, kana zvinyorwa zveboka rimwe chete rechigadzirwa zvisingaenderani, kuchinja kwakasiyana kwemuviri nemakemikari kunoitwa. Zvishandiso zvinonyanya kunzwa kune laser mhedzisiro. Kazhinji, chigadzirwa chimwe chete chine maitiro akafanana, asi zvakasiyana-siyana zvinotungamirira kune kukanganisa kwechigadzirwa. Mhedzisiro yacho yakasiyana nekuti kukosha kwelaser simba iyo yega yega inogona kugamuchira yakasiyana, izvo zvinotungamira kune zvisirizvo muchigadzirwa.
