Kare muna 1916, nyanzvi yefizikisi yechiJudha yakakurumbira Einstein akawana chakavanzika chemalaser. Laser (zita rizere: Chiedza Amplification neStimulated Emission of Radiation), zvichireva kuti "kukwidziridzwa nemwaranzi yakasimudzwa yechiedza", inorumbidzwa seimwe huru kugadzirwa kwevanhu kubva muzana ramakore rechi20, ichitevera simba renyukireya, makomputa, uye semiconductors. Ndiyo "banga rinokurumidza", "mutongi akanyatsojeka", uye "chiedza chakajeka". Iro zita rakazara rechiRungu relaser rinotoratidza zvizere maitiro ekugadzira laser. Laser ine huwandu hwakasiyana hwekushandisa, senge laser yekumaka, laser welding, laser yekucheka, fiber optic kutaurirana, laser inotangira, LiDAR, zvichingodaro. Nhasi tichataura nezve ma lasers anowana kureba kuyerwa basa.
The musimboti Laser zvichidzika
Kazhinji kutaura, kune nzira mbiri dzekuyera chinhambwe uchishandisa lasers: pulse nzira uye chikamu nzira. Nheyo yelaser pulse kutangira ndeyekuti iyo laser inoburitswa nelaser emission mudziyo inoratidzwa neyakayerwa chinhu uye yobva yagamuchirwa neanogamuchira. Nekurekodha panguva imwe chete yelaser's round-trip, hafu yechigadzirwa chekumhanya kwechiedza uye nekudzoka-rwendo nguva chinhambwe chiri pakati pechiridzwa chinotenderera nechinhu chakayerwa. Iko kurongeka kwepulse nzira yekuyera kureba kunowanzo kutenderera +/- 10 masendimita. Iyo nzira yechikamu haiyere chikamu chelaser, asi inoyera chikamu chechiratidzo chakagadziridzwa pane laser.
Nzira yekurapa laser
Mushure mekunzwisisa musimboti welaser kubva, ngatitarisei kushanda chaiko kwelaser kubva. Kazhinji, kunyatsoita laser kutenderera kunoda kushandiswa kweiyo yakazara kuratidza prism, nepo rangefinder inoshandiswa kuyerwa kweimba inogona kuyera zvakananga kuratidzwa kubva pamadziro akatsetseka. Izvi zvinodaro nekuti chinhambwe chiri padyo, uye simba rechiratidzo rinoratidzwa kumashure nechiedza rakasimba zvakakwana. Nekudaro, kana chinhambwe chiri kure, iyo laser emission angle inofanirwa kuve perpendicular kune yakazara inoratidzira girazi, zvikasadaro chiratidzo chekudzoka chichave chisina kusimba kuwana chinhambwe chaicho. Nekudaro, muhuinjiniya hunoshanda, vashandi vanoshanda nelaser inotangira vanozoshandisa mapepa epurasitiki matete senzvimbo inovhenekera kugadzirisa dambudziko reyakanyanya laser diffuse reflection.Muchina wemhando yepamusoro welaser unogona kuwana kuyerwa kweanosvika mirimita, kugadzira lasers akakodzera. zvakasiyana-siyana zvepamusoro-chaizvo zvekuyera zvinangwa.
Sebhizimusi repamusoro-soro rinobatanidza kutsvagisa nekusimudzira nekugadzirwa, Lumisopot yakazvimiririra yakagadzira 905nm 1200m semiconductor laser kubva mamodules, 1535nm 3-15km erbium girazi laser kubva modules, uye mamwe marefu marefu laser kuyerwa modules. Kusiyana nemamwe makambani 'laser kubva zvigadzirwa, zvigadzirwa zvedu zvinoratidza zvizere hunhu hwehukuru hudiki, huremu huremu, kudhura kwakanyanya, uye kugona kuendesa yakawanda. Uyezve, zvigadzirwa zvedu zvemhando dzakasiyana siyana uye zvinogona kusangana nemhando dzese dzelaser. Kana iwe uchifarira zvigadzirwa zvedu, ndapota inzwa wakasununguka kutibata nesu.
