Tsanangudzo yekusarudza single-mode fiber laser

Referensi yekusarudzalaser yefaibha yemhando imwe chete
Mukushandisa kwakakodzera, kusarudza nzira imwe chete yakakodzeralaser yefaibhainoda kuyera kwakarongeka kwezvikamu zvakasiyana-siyana kuti ive nechokwadi chekuti mashandiro ayo anoenderana nezvinodiwa zvekushandisa, nzvimbo yekushanda uye bhajeti. Chikamu chino chichapa nzira inoshanda yekusarudza zvichienderana nezvinodiwa.
Nzira yekusarudza yakavakirwa pamamiriro ekushandisa
Zvinodiwa pakuita basa relaserszvinosiyana zvakanyanya mumamiriro akasiyana ekushandisa. Danho rekutanga pakusarudza nderekujekesa zvinodiwa zvikuru zvekushandisa.
Kugadzirisa zvinhu nemazvo uye kugadzira micro-nano: Mashandisirwo akadaro anosanganisira kucheka zvakanaka, kuboora, semiconductor wafer dicing, micron-level marking uye 3D printing, nezvimwewo. Ane zvinodiwa zvakanyanya zvemhando ye beam uye focused spot size. Laser ine M² factor iri pedyo ne 1 (yakadai se <1.1) inofanira kusarudzwa. Simba rekubuda rinofanira kutariswa zvichienderana nekukora kwezvinhu uye kumhanya kwekugadzirisa. Kazhinji, simba rinotangira pamakumi kusvika kumazana e watts rinogona kusangana nezvinodiwa zve micro-processing yakawanda. Panyaya ye wavelength, 1064nm ndiyo sarudzo inosarudzwa ye simbi yakawanda yekugadzirisa zvinhu nekuda kwe high absorption rate yayo uye mutengo wakaderera pa watt ye laser power.
Tsvagiridzo yesainzi uye kuyerwa kwepamusoro-soro: Zviitiko zvekushandisa zvinosanganisira ma tweezers e optical, fizikisi yeatomu inotonhora, spectroscopy yepamusoro-soro uye interferometry. Minda iyi inowanzo kuve nekutsvaga kwakanyanya kwe monochromaticity, kugadzikana kwema frequency uye mashandiro eruzha ema lasers. Mamodheru ane linewidth yakamanikana (kunyangwe single frequency) uye ruzha rwakaderera-simba anofanirwa kupihwa pekutanga. Wavelength inofanira kusarudzwa zvichibva pamutsetse we resonance weatomu kana molecule chaiyo (semuenzaniso, 780nm inowanzo shandiswa pakutonhodza maatomu erubidium). Bias maintenance output inowanzo dikanwa pakuedza kupindira. Simba rinodiwa kazhinji harisi rakakwirira, uye mazana emamiriyoni kusvika kune ma watts akati wandei anowanzo kukwana.
Zvekurapa uye zvebiotechnology: Mashandisirwo anosanganisira kuvhiyiwa kwemaziso, kurapwa kweganda uye fluorescence microscopy imaging. Kuchengetedzeka kwemaziso ndiko kunonyanya kufungwa nezvako, saka ma laser ane ma wavelength e1550nm kana 2μm, ari mubhendi rekuchengetedza maziso, anowanzo sarudzwa. Pamashandisirwo ekuongorora, kutarisisa kunofanirwa kupihwa kugadzikana kwesimba; Pamashandisirwo ekurapa, simba rakakodzera rinofanira kusarudzwa zvichienderana nekudzika kwekurapwa uye zvinodiwa nesimba. Kuchinjika kwe optical transmission ibatsiro guru mumashandisirwo akadaro.
Kutaurirana uye Kunzwa: Kunzwa kwefiber optic, liDAR uye kutaurirana kwemhepo munzvimbo ndizvo zvinoshandiswa zvakanyanya. Izvi zvinodalaserkuva nekuvimbika kwakanyanya, kugona kuchinjika nharaunda uye kugadzikana kwenguva refu. Bandi re1550nm rave sarudzo inofarirwa nekuda kwekurasikirwa kwaro kwakaderera kwekutumira mufibers dze optical. Kune masisitimu ekuona akabatana (akadai se coherent lidar), laser ine polarized linearly ine linewidth yakamanikana inodiwa se local oscillator.
2. Kuronga zvakakosha zvema parameter akakosha
Kana paine zvinhu zvakawanda zvinotarwa, sarudzo dzinogona kuitwa zvichibva pane zvinotevera:
Zviyero zvinosimbisa: Kutanga, sarudza hurefu hwewavelength uye hunhu hwemwaranzi. Wavelength inotsanangurwa nezvinodiwa zvakakosha zvekushandiswa (hunhu hwekushandisa zvinhu, zviyero zvekuchengetedza, mitsetse yeatomu), uye kazhinji hapana mukana wekukanganisa. Hunhu hwemwaranzi hunosarudza zvakananga kugona kwekushandisa. Semuenzaniso, kugadzira nemazvo hakugamuchire lasers ine M² yakakwira zvakanyanya.
Magadzirirwo ekushanda: Chechipiri, teerera simba rekubuda uye upamhi hwemutsara/polarization. Simba rinofanira kusangana nezvinodiwa zvesimba kana kushanda zvakanaka kwekushandisa. Hunhu hwemutsara nepolarization hunotsanangurwa zvichibva panzira chaiyo yehunyanzvi yekushandisa (senge kana kupindira kana kuwanda kwefrequency kuripo). Magadzirirwo anoshanda: Chekupedzisira, funga nezvekugadzikana (senge kugadzikana kwesimba rekubuda kwenguva refu), kuvimbika (nguva yekushanda isina kukanganisa), kushandiswa kwesimba revhoriyamu, kuenderana kweinterface uye mutengo. Magadzirirwo aya anokanganisa kuoma kwekubatanidza uye mutengo wese wekuva muridzi welaser munzvimbo chaiyo yekushanda.

3. Kusarudzwa uye kutongwa pakati pemodhi imwe chete nemodhi dzakawanda
Kunyangwe chinyorwa chino chichinyanya kutaura nezve single-modemalaser efaibha, zvakakosha kunzwisisa zvakajeka kukosha kwekusarudza single-mode pakusarudzwa chaiko. Kana zvinodiwa zvikuru zveapplication zviri zve highest processing accuracy, the long-substance-in-heat-depression zone, the last focusability capacity kana the long-long transmission distance, single-mode fiber laser ndiyo chete sarudzo chaiyo. Kusiyana neizvi, kana application ichinyanya kusanganisira gobvu plate welding, large-area surface treatment kana short-distance high-power transmission, uye absolute accuracy requirement isiri yakakwira, saka multimode fiber lasers inogona kuva sarudzo inodhura uye inoshanda nekuda kwesimba rayo rakawanda uye mutengo wakaderera.
