Mfundo ndi mitundu ya laser

Mfundo ndi mitundu yalaser
Laser ndi chiyani?
Laser (kuwunikira kuunika polimbikitsa kupatsidwa radiation); Kuti mupeze lingaliro labwino, yang'anani chithunzichi pansipa:

Matomu okwera pamlingo wapamwamba kwambiri osintha mpaka kutsika kwamphamvu ndikutulutsa chithunzi, njira yotchedwa radiation yokha.
Otchuka amatha kumvedwa monga: mpira pansi ndi malo ake abwino kwambiri, pomwe mpira umakankhidwira mlengalenga ndi mphamvu yakunja (yotchedwa kuponyera), mpira umagwera mphamvu yayitali. Mpira ndi atomu, ndiye kuti atomu imatulutsa chithunzi cha kuchuluka kwamphamvu panthawi yosintha.

Gulu la Lasers
Anthu akhala akudziwa mfundo ya a Laser Laser, adayamba kupanga ma laser osiyanasiyana, ngati malinga ndi zida za laser kuti apangire, amatha kugawidwa m'masitolo, laser yolimba, semiconductor laser, etc ..
1, gasi lasergation: atomu, molek, ion;
Zogwira ntchito ya laser yamagesi ndi mpweya kapena nthunzi yachitsulo, yomwe imadziwika ndi mitundu yayikulu ya laser. Chofala kwambiri ndi chaser ya co2, momwe CO2 imagwiritsidwa ntchito ngati chinthu chogwirira ntchito chopangidwa ndi 106um potengera zotulutsa zamagetsi.
Chifukwa chogwirira ntchito laser ya gasi ndi mpweya, mawonekedwe a laser ndi akulu kwambiri, ndipo omwe akutuluka lapula ya laser yamasamba ndi yayitali. Chifukwa chake, a Lasers a Lasers adachotsedwa pamsika, ndipo adangogwiritsidwa ntchito kumadera ena, monga masinthidwe a pulasitiki ena.
2, laser yolimbaGulu: Ruby, ND: YAG, etc.;
Zida zogwirira ntchito la State State ndi Ruby, newdymium Galasi, YNTRIum Aluminium adyot (yag), etc.
Laser yolimba-boma imapangidwa ndi mankhwala ogwirira ntchito, kupondaponda, kaponidwe ndi kusefukira kwamanja. Ndi mawonekedwe apadera a atomu yazitsulo yomwe imapanga tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono (ingonetsani mipira yambiri pansi, ndipo imapanga ma buloni a laser) Kutulutsa magalasi (mandala akunja). Kutulutsa kwa laser kenako kudzera mu kapangidwe kake kameneka, mapangidwe a laser laser.

3, Semiconductor laser
Ponena za Semicoctor Lasers, itha kumveketsa ngati pncodiode, pali zokambirana za PN, ndipo nthawi zina zimawonjezedwa, kusintha kwa semiconductor kumapangidwa kuti itulutse zithunzi. Pamene mphamvu ya laser yomwe yatulutsidwa ndi semiconductor ndi yaying'ono, chipangizo chotsika kwambiri cha semiclaser, kotero chiberekero cha fiber chidapangidwa. Ngati mphamvu ya semiconductor ya semiconduc imakulitsidwa mpaka kufika poti zitha kutulutsa mwachindunji zida zopangira, zimakhala semiconductor yofiyira. Pakadali pano, Semiconduct a Semiconductor Lasers pamsika wafika pamlingo wa 10,000-watt.

Kuphatikiza pa ma angalawa angapo pamwambapa, anthu nawonso apanganso ma lasers amadzimadzi, omwe amatchedwanso mafuta a mafuta. Madzi am'madzi ali ovuta kwambiri pakugwiritsa ntchito voliyumu ndi ntchito kuposa zolimba ndipo samagwiritsidwa ntchito kawirikawiri.
