MOPA & Q-Switched Fiber Laser
MOPA ndiyo acronym ye Master Oscillator Power Amplifier. MOPA Laser inoreva chimiro chelaser umo laser oscillator uye amplifier zvinoputika. Munyika yemaindasitiri, MOPA laser inoreva yakasarudzika, yakawedzera "hungwaru" nano2nd pulsed fiber laser inoumbwa ne semiconductor laser seed sosi uye fiber amplifier inofambiswa nemagetsi pulses.
"Hungwaru" hwayo hunonyanya kuratidzwa mune yakazvimiririra inogadziriswa kubuda pulse hupamhi (kubva pa2 ns kusvika ku500 ns), uye iyo yekudzokorora frequency inogona kunge yakakwira semegahertz. Iyo mhodzi sosi chimiro cheQ-switched fiber laser ndeyekuisa yekurasikirwa modulator mufiber oscillating cavity, iyo inoburitsa nano2nd pulse light kubuda neimwe pulse hupamhi nekugara ichigadzirisa kurasikirwa kwemaziso mugomba.
Nano2nd pulsed lasers inonyanyozivikanwa nezve maindasitiri ekushandisa senge simbi yekumaka, welding, kuchenesa, uye kucheka. Semashandisirwo maviri makuru e nano2nd pulsed lasers, ndeupi mutsauko uye zvakanakira MOPA chimiro uye Q-inochinja chimiro? Kune iri dambudziko rinowanzo kunetsa munhu wese, isu tichaita ongororo yakapusa kubva mukati meiyo laser chimiro, inobuda optical paramita uye mamiriro ekushandisa.
Yemukati Mamiriro Kuenzanisa
Kuenzanisa kwemukati chimiro uye musimboti weMOPA fiber laser jenareta uye Q-switched fiber laser jenareta.
Musiyano wemukati wechimiro pakati peMOPA fiber laser neQ-switched fiber laser inonyanya munzira yekugadzira iyo pulse seed optical signal.
Iyo MOPA fiber laser pulse seed optical chiratidzo inogadzirwa nemagetsi pulse inotyaira semiconductor laser chip, ndiko kuti, iyo inobuda optical chiratidzo inogadziriswa nekutyaira chiratidzo chemagetsi, saka ine simba rakasimba rekugadzira akasiyana pulse paramita ( pulse wide, repetition frequency, pulse shape uye simba).
Iyo pulsed seed optical chiratidzo cheQ-switched fiber laser inogadzira pulsed light kubuda nekuwedzera nguva nenguva kana kuderedza kurasikirwa kwemaziso mune resonator, uye ine chimiro chakareruka uye mutengo mukana. Nekudaro, nekuda kwepesvedzero ye-Q-switched zvishandiso, iyo pulse paramita ishoma.
Optical Parameters Kuenzanisa
Iyo inobuda pulse hupamhi yeMOPA fiber laser inogadziriswa yakazvimiririra. Iyo pulse yakafara yeMOPA fiber lasers inoturika zvisina tsarukano (kubva pa2 ns kusvika pa500 ns). Iyo yakatetepa iyo pulse hupamhi, iyo diki iyo inopisa-yakakanganiswa nzvimbo, uye yakakwirira iyo machining accuracy inogona kuwanikwa. Iyo inobuda pulse hupamhi hweiyo Q-switched fiber laser haigadzirike, uye inobuda pulse hupamhi haiwanzo kuchinjika pane yakatarwa kukosha kwe80 ns kusvika 140 ns.
MOPA faibha lasers ane yakafara kudzokorora frequency renji. MOPA laser repetition frequency inogona kusvika kune yakakwira frequency kubuda kweMHz. Yakakwira yekudzokorora frequency inoreva kukwirira kwekugadzirisa, uye MOPA inogona kuramba ichichengetedza yakakwirira yepamusoro peak masimba pasi peyakanyanya kudzokorora frequency mamiriro. Nekuda kwekuganhurirwa kwemamiriro ekushanda eQ-switch, iyo Q-switched fiber laser ine yakamanikana kubuda frequency renji, uye yakakwirira frequency inogona kusvika ~ 100 kHz.

Alumine Sheet Yakabviswa Surface Applications
Iye zvino, akawanda uye akaonda zvigadzirwa zvemagetsi, nharembozha dzakawanda, mahwendefa, makomputa ari kushandisa yakaonda aluminium oxide sechigadzirwa chegoko. Uchishandisa laser Q-switch mune yakaonda aluminium plate yekumaka inotungamira inogona, inotungamira nyore kune deformation yechinhu, abaxially inogadzirwa "convex hull", inokanganisa chitarisiko. Iwo ma paramita eMOPA laser pulse wide idiki, ayo anogona kuita kuti zvinhu zvive nyore kudhirikira, shading yakanyanya kutetepa uye kuchena kuchena. Izvi zvinokonzerwa nelaser MOPA shandisa iyo pulse wide parameter inogona kuita kuti laser igare panguva yechinhu ipfupi, uye yakaringana simba repamusoro rinogona kubvisa anode layer, saka kune yakaonda aluminium plate surface stripping anode processing, MOPA laser isarudzo iri nani.
Anodic Alumina's Black Marking Applications
Kushandiswa kwelaser muanodic alumina pamusoro inomaka mucherechedzo mutema, modhi uye zvinyorwa, iko kushandiswa mumakore maviri apfuura zvishoma nezvishoma Apple, Huawei, Lenovo, Samsung vagadziri vemagetsi vanoshandiswa zvakanyanya kune zvemagetsi chigadzirwa goko, rinoshandiswa kumaka mutema mucherechedzo, modhi, nezvimwewo. Nekuti ine yakafara pulse hupamhi uye pulse frequency gadziriso renji yelaser MOPA neyakatetepa pulse hupamhi uye yakakwirira frequency paramita inogona kunge iri pamusoro pezvinhu zvakamisikidzwa mhedzisiro yevatema, kuburikidza neakasiyana masanganiswa emaparamita anogona zvakare kutamba akamaka mhedzisiro yegrey yakasiyana.
Electronic, Semiconductor, ITO Precision Machining Application
Mune zvemagetsi, semiconductor, uye ITO uye kumwe kurongeka machining, inonyanya kuda kushandisa mutsara wekumaka. nekuda kweQ-switch laser chimiro, haigone kugadzirisa iyo pulse width parameters, saka mutsara wakaoma kuwana zvakanaka. Iyo MOPA laser inogona kuchinjika kugadzirisa iyo pulse hupamhi uye frequency paramita, iyo isingagone kungoita mutsara wakanaka, asiwo mupendero hausi wakatsetseka.
Pamusoro penyaya dzakati wandei dzekushandisa, kune akawanda akasiyana mashandisirwo eMOPA laser uye Q-switch laser, heino mimwe mienzaniso yakajairika yemashandisirwo ane tafura inotevera:
