Reference yekusarudzasingle-modhi fiber laser
Mumashandisirwo anoshanda, kusarudza yakakodzera single-modhifiber laserinoda kuyera kwakarongeka kweakasiyana ma paramita kuti ive nechokwadi chekuti kuita kwayo kunoenderana nezvinodiwa zvekushandisa, nharaunda yekushanda uye zvimhingamipinyi zvebhajeti. Ichi chikamu chinopa inoshanda sarudzo nzira zvichienderana nezvinodiwa.
Sarudzo nzira yakavakirwa pane application mamiriro
Izvo zvinodiwa zvekuita zvelaserssiyana zvakanyanya kune akasiyana maapplication mamiriro. Nhanho yekutanga pakusarudza ndeyekujekesa zvakakosha zvechikumbiro.
Precision material processing uye micro-nano kugadzira: Zvishandiso zvakadaro zvinosanganisira kucheka kwakanaka, kuchera, semiconductor wafer dicing, micron-level marking uye 3D kudhinda, nezvimwewo. Vane zvakanyanya zvakanyanya zvinodiwa zvemhando yedanda uye saizi yenzvimbo yakatarisana. Laser ine M² factor padyo sezvinobvira kune 1 (senge <1.1) inofanira kusarudzwa. Iro simba rinobuda rinoda kutariswa zvichienderana nehupamhi hwezvinhu uye kumhanya kwekugadzirisa. Kazhinji, simba rinobva pamakumi kusvika kumazana ewatts rinogona kusangana nezvinodiwa zveakawanda micro-processing. Panyaya yewavelength, 1064nm ndiyo sarudzo inosarudzika kune yakawanda simbi inogadziriswa nekuda kweiyo yakanyanya kunyura mwero uye yakaderera mutengo pawatt yemagetsi laser.
Tsvagiridzo yesainzi uye kuyerwa kwepamusoro-soro: Mamiriro ekushandisa anosanganisira optical tweezers, inotonhora atomu fizikisi, yakakwirira-resolution spectroscopy uye interferometry. Iyi minda inowanzo kuve nekunyanya kutsvaga kweiyo monochromaticity, frequency kugadzikana uye ruzha kuita kwema lasers. Mamodheru ane nhete mutsara (kunyangwe kamwe chete frequency) uye yakaderera-yakanyanya ruzha inofanira kupihwa pekutanga. Hurefu hwemasaisai hunofanirwa kusarudzwa zvichibva pamutsara weresonance yeatomu chaiyo kana molecule (semuenzaniso, 780nm inowanzoshandiswa pakutonhodza maatomu erubidium). Bias kuchengetedza kubuda kunowanzodikanwa pakukanganisa kuedza. Simba rinodiwa kazhinji harina kukwirira, uye mazana emazana emamilliwatts kune akati wandei watts anowanzo kukwana.
Medical uye biotechnology: Zvikumbiro zvinosanganisira kuvhiyiwa kwemaziso, kurapwa kweganda uye fluorescence microscopy imaging. Kuchengetedzeka kweziso ndiko kutariswa kwekutanga, saka ma lasers ane wavelengths ye1550nm kana 2μm, ari mubhendi rekuchengetedza maziso, anowanzo kusarudzwa. Kune maapplication ekuongorora, kutarisisa kunoda kubhadharwa kune kugadzikana kwemagetsi; Pamashandisirwo ekurapa, simba rakakodzera rinofanira kusarudzwa zvichienderana nekudzika kwekurapa uye simba rinodiwa. Iko kuchinjika kweiyo optical kutapurirana chinhu chikuru chakanakira mune zvakadaro maapplication.
Kukurukurirana uye Kunzwa: Fiber optic sensing, liDAR uye space Optical kutaurirana ndiwo akajairika maapplication. Aya mascenario anodalaserkuve nekuvimbika kwepamusoro, kuchinjika kwezvakatipoteredza uye kugadzikana kwenguva refu. Iyo 1550nm bhendi yave sarudzo yakasarudzika nekuda kwekuderera kwayo kwekutapurirana kurasikirwa mumafiber optical. Kune akabatana ekuona masisitimu (seyakabatana lidar), mutsara polarized laser ine yakanyanya kutetepa mutsetse inodiwa seyenzvimbo oscillator.
2. Kurongeka kwakakosha kwezvikamu zvakakosha
Takatarisana neakawanda ma parameter, sarudzo dzinogona kuitwa zvichibva pane zvinotevera zvakakosha:
Decisive parameters: Chekutanga, sarudza wavelength uye beam mhando. Iyo wavelength inotarwa nezvinodiwa zvakakosha zvechishandiso (material absorption maitiro, kuchengetedza mwero, atomic resonance mitsara), uye kazhinji hapana nzvimbo yekukanganisa. Iyo beam mhando inosarudza zvakananga kugona kwechishandiso. Semuenzaniso, chaiyo machining haigone kugamuchira lasers ine yakawandisa yakakwira M².
Performance paramita: Chechipiri, teerera kune inobuda simba uye mutsara upamhi / polarization. Simba racho rinofanira kusangana nechikumbaridzo chesimba kana kuti zvinodikanwa zvekushandisa. Iyo linewidth uye polarization maitiro anotemerwa zvichibva pane chaiyo tekinoroji nzira yechishandiso (senge kupindira kana frequency kaviri inobatanidzwa). Inoshanda parameters: Pakupedzisira, funga kugadzikana (sekureba kwenguva refu yekubuda kwesimba kugadzikana), kuvimbika (kukanganisa-isina nguva yekushanda nguva), vhoriyamu simba rekushandisa, interface kuenderana uye mutengo. Aya ma paramita anokanganisa kuomerwa kwekubatanidza uye mutengo wakakwana wevaridzi welaser munzvimbo chaiyo yekushanda.
3. Kusarudzwa uye kutonga pakati pe-single-mode uye multi-mode
Kunyangwe chinyorwa ichi chinotarisa pane imwe-modhifiber lasers, zvakakosha kuti unzwisise zvakajeka kukosha kwekusarudza imwe-modhi mukusarudza chaiko. Kana izvo zvakakosha zvechikumbiro chiri chepamusoro-soro chekugadzirisa, idiki-inokanganisa kupisa-nzvimbo, iyo yekupedzisira yekutarisa kugona kana kureba kwekufambisa kureba, imwe-modhi fiber laser ndiyo yega sarudzo chaiyo. Sezvineiwo, kana application yacho ichinyanya kusanganisira gobvu plate welding, hombe-nzvimbo yekumusoro kurapwa kana kupfupi-refu-yakakwirira-simba kutapurirana, uye mhedziso yechokwadi inodiwa haina kukwirira, saka multimode fiber lasers inogona kuve ine hupfumi uye inoshanda sarudzo nekuda kwesimba rawo rakazara uye mutengo wakaderera.
