Ma'anar Nanosecond, Picosecond, da Laser Femtosecond
Nanosecond Laser An fara gabatar da shi a cikin filin masana'antu a ƙarshen 1990s azaman lasers-pumped solid-state (DPSS). Koyaya, irin waɗannan na'urori na farko suna da ƙarancin fitarwa na watts kaɗan da tsayin 355nm. A tsawon lokaci, kasuwa don nanosecond Laser ya girma, kuma yawancin lasers yanzu suna da tsawon lokaci na bugun jini a cikin dubun zuwa ɗaruruwan nanoseconds.
Laser Picosecond Laser ne mai tsayin gajeriyar bugun bugun jini wanda ke fitar da bugun jini-matakin picosecond. Waɗannan lasers suna ba da faɗin bugun bugun jini mai ɗan gajeren gajere, mitar maimaita daidaitacce, ƙarfin bugun jini mai ƙarfi, kuma sun dace don aikace-aikace a cikin biomedicine, oscillation na gani na gani, da hoton microscopic na halitta. A cikin tsarin nazarin halittu na zamani da tsarin bincike, picosecond lasers sun zama kayan aiki masu mahimmanci.
Femtosecond Laser Laser ne gajeriyar bugun jini mai tsayi mai tsananin gaske, ana ƙididdige shi a cikin dakika biyu. Wannan fasaha ta ci gaba ta samar wa mutane sabbin damar gwaji da ba a taba ganin irinta ba kuma tana da fa'idam aikace-aikace. Yin amfani da Laser mai ƙarfi, gajeriyar bugun femtosecond laser don dalilai na ganowa yana da fa'ida musamman ga halayen sinadarai daban-daban, gami da amma ba'a iyakance ga rarrabuwa ba, sabon haɓakar haɗin gwiwa, proton da canja wurin lantarki, isomerization fili, rabuwar kwayoyin, saurin gudu, kusurwa. , da kuma rarraba jihar na matsakaicin amsawa da samfurori na ƙarshe, halayen sinadaran da ke faruwa a cikin mafita da tasirin maganin kaushi, da kuma tasirin tasirin kwayar halitta da juyawa akan halayen sinadaran.
Raka'a Juyin Lokaci don Nanoseconds, Picoseconds, da Femtoseconds
1ns (nanosecond) = 0.0000000001 seconds = 10-9 seconds
1ps (picosecond) = 0.000000000001 seconds = 10-12 seconds
1 fs (femtosecond) = 0.00000000000001 seconds = 10-15 seconds
Nanosecond, picosecond, da femtosecond Laser kayan sarrafa kayan aikin da aka fi gani a kasuwa ana suna bisa lokaci. Sauran abubuwa, kamar makamashin bugun jini guda ɗaya, faɗin bugun jini, mitar bugun jini, da ƙarfin bugun bugun jini, suma suna taka rawa wajen zaɓar kayan aikin da suka dace don sarrafa kayan daban-daban. Lokacin da ya fi guntu, ƙananan tasiri a kan kayan abu, yana haifar da sakamako mai kyau.
Aikace-aikacen likitanci na Picosecond, Femtosecond, da Nanosecond Lasers
Nanosecond Laser na zaɓin zafi da lalata melanin a cikin fata, wanda sai sel suna kawar da su daga jiki, wanda ke haifar da dusar ƙanƙara na raunuka masu launi. Ana amfani da wannan hanyar da yawa don maganin cututtukan pigmentation. Laser na Picosecond suna aiki cikin babban sauri, suna rushe ƙwayoyin melanin ba tare da lalata fata da ke kewaye ba. Wannan hanya yadda ya kamata ya bi da pigmented cututtuka kamar nevus na Ota da Brown cyan nevus. Femtosecond Laser aiki a cikin nau'i na bugun jini, wanda zai iya fitar da babbar iko a nan take, mai girma ga lura da myopia.
Tsarin sanyaya don Picosecond, Femtosecond, da Nanosecond Lasers
Komai nanosecond, picosecond ko femtosecond Laser, wajibi ne don tabbatar da aikin yau da kullun na shugaban Laser da haɗa kayan aiki tare da Laser chiller. Madaidaicin kayan aikin laser, mafi girman daidaiton sarrafa zafin jiki. TEYU ultrafast Laser chiller yana da kwanciyar hankali na zafin jiki na ± 0.1 ° C da saurin sanyaya, wanda ke tabbatar da cewa laser yana aiki a yanayin zafi akai-akai kuma yana da ingantaccen fitowar katako, don haka inganta rayuwar sabis na Laser. TEYU ultrafast Laser chillers sun dace da duk waɗannan nau'ikan kayan aikin laser guda uku.
