Menene Laser?
LASER (Ƙara Haske ta Ƙarfafa Fitar da Radiation); Don samun kyakkyawar fahimta, kalli hoton da ke ƙasa:
Zarra a mafi girman matakin makamashi ba tare da bata lokaci ba yana jujjuyawa zuwa matakin ƙaramar makamashi kuma yana fitar da photon, wani tsari da ake kira raɗaɗi maras lokaci.
Ana iya fahimtar shaharar kamar haka: ƙwallon da ke ƙasa shine matsayi mafi dacewa, lokacin da aka tura kwallon zuwa cikin iska ta hanyar waje (wanda ake kira famfo), lokacin da ƙarfin waje ya ɓace, ƙwallon yana fadowa daga tsayi mai tsayi, kuma ya saki. wani adadin kuzari. Idan ƙwallon ƙayyadaddun zarra ne, to wannan zarra yana fitar da hoto na takamaiman tsayin daka yayin sauyawa.
Rarraba Laser
Mutane sun ƙware da ka'idar Laser tsara, fara ci gaba daban-daban siffofin Laser, idan bisa ga Laser aiki abu don rarraba, za a iya raba gas Laser, m Laser, semiconductor Laser, da dai sauransu.
1, Gas Laser Rarraba: zarra, kwayoyin, ion;
Abubuwan da ke aiki na Laser gas shine gas ko tururi na ƙarfe, wanda ke da girman kewayon fitarwa na laser. Mafi na kowa shine CO2 Laser, wanda CO2 ake amfani dashi azaman kayan aiki don samar da laser infrared na 10.6um ta hanyar motsa jiki na fitarwa na lantarki.
Saboda kayan aiki na Laser gas gas ne, tsarin gaba ɗaya na Laser ya yi girma sosai, kuma ƙarfin fitarwa na Laser gas ɗin ya yi tsayi da yawa, aikin sarrafa kayan ba shi da kyau. Don haka, ba da daɗewa ba aka kawar da Laser gas daga kasuwa, kuma ana amfani da su ne kawai a wasu takamaiman wurare, kamar alamar laser na wasu sassa na filastik.
2, m Laserrarrabuwa: ruby, Nd:YAG, da dai sauransu;
The aiki abu na m jihar Laser ne Ruby, neodymium gilashin, Yttrium aluminum garnet (YAG), da dai sauransu, wanda shi ne wani karamin adadin ions uniformly shigar a cikin crystal ko gilashin kayan a matsayin matrix, da ake kira aiki ions.
A m-jihar Laser ne hada da wani aiki abu, a famfo tsarin, a resonator da kuma sanyaya da tace tsarin.The black square a tsakiyar hoton da ke ƙasa ne Laser crystal, wanda yayi kama da haske-launi m gilashin da kuma ya ƙunshi kristal mai haske da aka yi da ƙarfe na ƙasa da ba kasafai ba. Yana da tsari na musamman na atom ɗin ƙarfe na ƙasa wanda ba kasafai ba wanda ke haifar da juzu'i na yawan jama'a lokacin da hasken haske ya haskaka (kawai fahimtar cewa yawancin ƙwallo a ƙasa ana tura su cikin iska), sannan kuma suna fitar da photon lokacin da barbashi ya canza, da lokacin Yawan photon ya isa, samuwar laser.Domin tabbatar da cewa laser da aka fitar ya fito a hanya daya, akwai cikakkun madubai (Lens na hagu) da madubin fitarwa mai tsaka-tsaki (Lens dama). Lokacin da fitarwa na laser sannan ta hanyar wani ƙirar gani, samuwar makamashin laser.
3, semiconductor Laser
Idan ya zo ga semiconductor lasers, ana iya fahimtarsa kawai azaman photodiode, akwai haɗin PN a cikin diode, kuma idan aka ƙara wani abu na yanzu, canjin lantarki a cikin semiconductor yana samuwa don saki photons, wanda ya haifar da laser. Lokacin da makamashin Laser da semiconductor ya fitar ya yi ƙanƙanta, ana iya amfani da na'ura mai ƙarancin ƙarfi azaman tushen famfo (tushen zuƙowa) nafiber Laser, don haka an kafa Laser fiber. Idan aka ƙara ƙarfin wutar lantarki na semiconductor har zuwa za a iya fitar da shi kai tsaye don sarrafa kayan, ya zama laser semiconductor kai tsaye. A halin yanzu, laser semiconductor kai tsaye a kasuwa sun kai matakin watt 10,000.
Baya ga na'urori masu yawa da ke sama, mutane kuma sun ƙirƙira na'urorin lesar ruwa, wanda kuma aka sani da Laser mai. Laser ruwa sun fi rikitarwa a girma da kayan aiki fiye da daskararru kuma ba safai ake amfani da su ba.
