1.disc laser
Chikumbiro cheiyo Disk Laser dhizaini dhizaini yakagadzirisa zvinobudirira dambudziko rekupisa kweiyo solid-state lasers uye yakawana musanganiswa wakakwana weavhareji simba repamusoro, simba repamusoro-soro, kushanda kwepamusoro, uye mhando yepamusoro yesimbi yakasimba-nyika lasers.Disk lasers yave isingadzokerike nyowani laser mwenje sosi yekugadzirisa muminda yemotokari, ngarava, njanji, ndege, simba uye mamwe minda.Ikozvino yakakwirira-simba disc laser tekinoroji ine simba rakakura re16 kilowatts uye danda remhando ye8 mm milliradians, iyo inogonesa robhoti laser kure kure welding uye yakakura-fomati laser yakakwirira-kumhanya yekucheka, kuvhura tarisiro yakafara yeakasimba-state lasers mu. munda wehigh-simba laser processing.Musika wekushandisa.
Zvakanakira zve disc lasers:
1. Modular chimiro
Iyo disc laser inotora modular chimiro, uye yega yega module inogona kukurumidza kutsiviwa panzvimbo.Iyo yekutonhodza sisitimu uye mwenje dhizaini sisitimu inosanganiswa neiyo laser sosi, ine compact chimiro, diki tsoka uye nekukurumidza kuisirwa uye kugadzirisa.
2. Yakanakisa danda yemhando uye yakajairwa
Yese TRUMPF disc lasers pamusoro pe2kW ine danda parameter chigadzirwa (BPP) yakamisikidzwa pa8mm/mrad.Iyo laser haichinji kune shanduko mukushandisa mode uye inoenderana neese TRUMPF optics.
3. Sezvo saizi yemuvara mu disc laser yakakura, iyo optical simba density inotsungirirwa neimwe optical element idiki.
Iyo yekukuvadza chikumbaridzo cheiyo optical element coating inowanzoita 500MW/cm2, uye kukuvara chikumbaridzo chequartz i2-3GW/cm2.Kuwanda kwesimba muTRUMPF dhisiki laser resonant cavity inowanzove isingasviki 0.5MW/cm2, uye kuwanda kwesimba pane yekubatanidza fiber isingasviki 30MW/cm2.Yakadaro yakaderera simba density haizokonzeri kukuvadza kune optical components uye haizobudisi nonlinear mhedzisiro, nokudaro kuve nechokwadi chekushanda kwekuvimbika.
4. Adopt laser simba real-time feedback control system.
Iyo chaiyo-nguva mhinduro yekudzora sisitimu inogona kuchengetedza simba richisvika paT-chidimbu yakagadzikana, uye mibairo yekugadzirisa ine yakanakisa kudzokorora.Iyo preheating nguva ye disc laser inenge zero, uye inogadziriswa simba renji i1% -100%.Sezvo disc laser inogadzirisa zvachose dambudziko rekupisa lens mhedzisiro, iyo laser simba, saizi yemavara, uye beam divergence angle yakagadzikana mukati meiyo yese simba renji, uye wave kumberi kwedanda hakuitike kukanganisa.
5. Iyo optical fiber inogona kuva plug-uye-kutamba apo laser inoramba ichimhanya.
Kana imwe optical fiber ikakundikana, kana uchitsiva optical fiber, iwe unongoda kuvhara nzira yeoptical fiber pasina kuvhara, uye mamwe mafiber optical anogona kuramba achiburitsa laser mwenje.Optical fiber kutsiva iri nyore kushanda, plug uye kutamba, pasina chero maturusi kana kurongeka kwekugadzirisa.Pane guruva-rinodzivirira mudziyo pamusuwo wemugwagwa kudzivirira zvakanyanya guruva kupinda munzvimbo ye optical component.
6. Yakachengeteka uye yakavimbika
Munguva yekugadziriswa, kunyangwe kana emissivity yezvinhu zviri kugadziriswa yakakwira zvekuti laser mwenje inoratidzwa ichidzokera mu laser, haizove nemhedzisiro pane iyo laser pachayo kana iyo yekugadzirisa maitiro, uye hapazove nekurambidzwa kugadzirisa zvinhu kana. urefu hwefiber.Kuchengetedzeka kwelaser operation kwakapihwa chitupa cheGerman chekuchengetedza.
7. Iyo yekupomba diode module iri nyore uye nekukurumidza
Iyo diode array yakaiswa pane yekupomba module zvakare ndeye modular kuvaka.Diode array modules ine hupenyu hurefu hwebasa uye inobvumirwa kwemakore matatu kana maawa makumi maviri.Hapana nguva yekudzikira inodikanwa ingave yakarongwa kutsiva kana kutsiva nekukurumidza nekuda kwekutadza kamwe kamwe.Kana module ikatadza, iyo yekudzora sisitimu inorira uye otomatiki inowedzera ikozvino yemamwe ma module nenzira kwayo kuti ichengetedze laser inobuda simba nguva dzose.Mushandisi anogona kuramba achishanda kwegumi kana kunyange gumi nemaviri emaawa.Kutsiva kupomba diode module panzvimbo yekugadzira iri nyore uye haidi kudzidziswa kwemushandisi.
2.2Fiber laser
Fiber lasers, semamwe ma lasers, anoumbwa nezvikamu zvitatu: a svikiro (doped fiber) anogona kugadzira mafotoni, optical resonant cavity inobvumira mafotoni kuti adzorerwe uye anokwidziridzwa mune yekuwana svikiro, uye pombi sosi inonakidza. photon transitions.
Zvimiro: 1. Optical fiber ine chiyero chepamusoro che "surface area / volume", yakanaka yekupisa kupisa, uye inogona kushanda nguva dzose pasina kumanikidzirwa kutonhora.2. Senge waveguide medium, optical fiber ine diki dhayamita yepakati uye inotarirwa kune yakakwira simba density mukati mefiber.Naizvozvo, mafiber lasers ane yakakwira shanduko inoshanda, yakaderera chikumbaridzo, yakakwira, uye yakatetepa mutsara, uye akasiyana neoptical fiber.Kubatana kurasikirwa kudiki.3. Nokuti optical fibers ane maitiro akanaka, fiber lasers iduku uye inoshanduka, inopindirana mukugadzirisa, inodhura, uye iri nyore kubatanidza muzvirongwa.4. Optical faibha zvakare ine zvakawanda zvinobatika parameters uye selectivity, uye inokwanisa kuwana yakaringana tuning renji, kupararira kwakanaka uye kugadzikana.
Fiber laser classification:
