Ma'anar Nanosecond, Picosecond, da Femtosecond Lasers

An fara gabatar da laser na Nanosecond a fannin masana'antu a ƙarshen shekarun 1990 a matsayin laser mai ƙarfi na diode (DPSS). Duk da haka, irin waɗannan laser na farko suna da ƙarancin ƙarfin fitarwa na watts kaɗan da kuma tsawon rai na 355nm. A tsawon lokaci, kasuwar laser na nanosecond ta girma, kuma yawancin lasers yanzu suna da tsawon bugun jini a cikin goma zuwa ɗaruruwan nanosecond.

Laser na Picosecond wani laser ne mai faɗi na bugun zuciya mai gajeru wanda ke fitar da bugun matakin picosecond. Waɗannan lasers suna ba da faɗin bugun zuciya mai gajeru, mita mai daidaitawa, ƙarfin bugun zuciya mai yawa, kuma sun dace da amfani a cikin maganin biomedicine, oscillation na gani, da kuma hoton microscopic na halitta. A cikin tsarin zamani na hoto da bincike, lasers na picosecond sun zama kayan aiki masu mahimmanci.

Laser na Femtosecond laser wani nau'in laser ne mai gajeren bugun jini mai ƙarfi sosai, wanda aka ƙididdige shi a cikin femtoseconds. Wannan fasaha mai ci gaba ta bai wa mutane sabbin damar gwaji da ba a taɓa gani ba kuma tana da fa'idodi masu yawa. Amfani da laser na femtosecond mai ƙarfi sosai, mai gajeren bugun jini don dalilai na ganowa yana da fa'ida musamman ga halayen sinadarai daban-daban, gami da amma ba'a iyakance ga yanke haɗin gwiwa ba, sabon samuwar haɗin gwiwa, canja wurin proton da electron, isomerization na mahaɗi, rarrabuwar ƙwayoyin cuta, saurin, kusurwa, da rarrabawar yanayin tsaka-tsakin amsawa da samfuran ƙarshe, halayen sinadarai da ke faruwa a cikin mafita da tasirin abubuwan narkewa, da kuma tasirin girgizar ƙwayoyin cuta da juyawa akan halayen sinadarai.

Raka'o'in Canza Lokaci don Nanoseconds, Picoseconds, da Femtoseconds

1ns (nanosecond) = 0.000000000001 daƙiƙa 1 = daƙiƙa 10-9

1ps (picosecond) = 0.00000000000000001 daƙiƙa 1 = daƙiƙa 10-12

1fs (femtosecond) = 0.0000000000000000000001 daƙiƙa 1 = daƙiƙa 10-15

Ana sanya wa na'urorin sarrafa laser nanosecond, picosecond, da femtosecond suna bisa ga lokaci. Sauran abubuwa, kamar kuzarin bugun jini ɗaya, faɗin bugun jini, mitar bugun jini, da ƙarfin bugun jini, suma suna taka rawa wajen zaɓar kayan aiki da suka dace don sarrafa kayan aiki daban-daban. Da zarar lokaci ya yi guntu, to, tasirin da ke kan saman kayan yana raguwa, wanda hakan ke haifar da ingantaccen tasirin sarrafawa.

Amfani da Lasers na Picosecond, Femtosecond, da Nanosecond a fannin likitanci

Nanosecond lasers suna dumama da lalata melanin a cikin fata, wanda ƙwayoyin halitta ke fitar da shi daga jiki, wanda ke haifar da ɓacewar raunuka masu launin fata. Ana amfani da wannan hanyar sosai don magance matsalolin launin fata. Ana amfani da lasers na Picosecond a cikin sauri, suna rushe ƙwayoyin melanin ba tare da lalata fatar da ke kewaye ba. Wannan hanyar tana magance cututtukan da ke da launin fata kamar nevus na Ota da Brown cyan nevus. Laser na Femtosecond yana aiki a cikin nau'in bugun jini, wanda zai iya fitar da babban ƙarfi nan take, mai kyau don maganin myopia.

Tsarin Sanyaya don Lasers na Picosecond, Femtosecond, da Nanosecond

Ko da kuwa nanosecond, picosecond ko femtosecond laser, ya zama dole a tabbatar da cewa kan laser ɗin yana aiki yadda ya kamata kuma a haɗa kayan aikin da na'urar sanyaya laser . Da zarar kayan aikin laser sun yi daidai, to, ingancin sarrafa zafin jiki ya fi girma. TEYU injin sanyaya laser mai sauri yana da daidaiton zafin jiki na ±0.1°C da kuma sanyaya cikin sauri, wanda ke tabbatar da cewa laser ɗin yana aiki a yanayin zafi mai ɗorewa kuma yana da fitowar haske mai ƙarfi, ta haka yana inganta rayuwar aikin laser ɗin.TEYU na'urorin sanyaya laser masu sauri sun dace da duk waɗannan nau'ikan kayan aikin laser guda uku.
