Makamashin bugun jini na Lasers

Ƙarfin bugun laser yana nufin kuzarin da bugun laser ke aikawa a kowace naúrar lokaci. Yawanci, lasers na iya fitar da raƙuman ruwa masu ci gaba (CW) ko raƙuman ruwa masu tasowa, tare da na ƙarshen yana da mahimmanci musamman a aikace-aikace da yawa kamar sarrafa kayan aiki, na'urar ji daga nesa, kayan aikin likita, da binciken kimiyya. Fahimtar halayen kuzarin bugun laser yana da mahimmanci don inganta aikinsa da inganta ingancin aikace-aikacen.

1. Ma'anar da auna kuzarin bugun jini

Ƙarfin bugun laser shine kuzarin da kowace bugun laser ke fitarwa, yawanci ana auna shi a cikin joules (J). Ba kamar lasers mai ci gaba da wave (CW) ba, lasers masu bugun laser suna fitar da kuzari cikin ɗan gajeren lokaci, kuma girman kuzarin yawanci yana da alaƙa da tsawon bugun zuciya (faɗin bugun zuciya) da ƙarfin kololuwa.

Ana iya ƙididdige kuzarin bugun jini ta amfani da dabarar da ke ƙasa: E = Ppeak × τ. Inda E shine kuzarin bugun jini (joules), Ppeak shine ƙarfin kololuwar bugun jini (watts), kuma τ shine tsawon bugun jini (dakika). Wannan yana nufin kuzarin bugun jini yana da alaƙa kai tsaye da ƙarfin kololuwa da faɗin bugun jini.

2. Abubuwan da ke Shafar Makamashin Pulse

Abubuwa da dama suna shafar kuzarin bugun jini na laser, ciki har da:

①Tsarin Laser da Nau'i:
Nau'o'in laser daban-daban suna shafar girman kuzarin bugun jini. Misali, laser mai ƙarfi yawanci yana ba da ƙarfin bugun jini mafi girma, wanda ya dace da aikace-aikacen da ke buƙatar babban ƙarfin fitarwa. A gefe guda kuma, laser ɗin fiber na iya samar da bugun jini mai ƙarfi ta hanyar daidaita tsawonsa.

②Tsawon Bugawa (Faɗin Bugawa):
Gajartar faɗin bugun jini, haka nan ƙarfin kololuwa ya fi girma a wani lokaci, wanda hakan ke ba da damar samun ƙarin kuzarin bugun jini. Faɗin bugun jini a cikin nanoseconds da picoseconds yawanci ana iya daidaitawa tsakanin nanoseconds da picoseconds, tare da amfani da gajerun bugun jini sosai a aikace-aikacen da suka dace saboda ƙarfin kololuwarsu mai girma.

③Ingancin Canza Wutar Lantarki da Ƙarfin Wutar Lantarki:
Ingancin laser ɗin kai tsaye yana ƙayyade yawan kuzarin da ake fitarwa. Wasu tsarin laser na iya haɓaka ingancin juyawa ta hanyar inganta ƙirar hanyar samun riba ko ramin laser, ta haka yana ƙara kuzarin bugun jini.

④Ƙaramin Laser:
A cikin tsarin laser mai ƙarfi da yawa, ana amfani da amplifiers don ƙara ƙarfin fitarwa. Ta hanyar ƙara girman matakai da yawa, ana iya ƙara ƙarfin bugun jini sosai.

⑤Layin Tuƙin Laser:
Wutar tuƙi ta tsarin laser diode ko laser babban abu ne da ke tasiri ga ƙarfin fitarwa da kuzarin bugunsa. Ta hanyar daidaita wutar lantarki, ana iya gyara yanayin motsin laser, wanda hakan ke shafar fitowar kuzarin bugun.

3. Amfani da Makamashin Pulse na Laser

Girman ƙarfin bugun laser yana ƙayyade dacewarsa ga fannoni daban-daban. Wasu aikace-aikacen da aka saba amfani da su sun haɗa da:

①Sarrafa Kayan Aiki:
A cikin walda, yankewa, da sassaka na laser, ana iya sarrafa kuzarin bugun jini daidai don cimma ingantaccen sarrafawa da daidaito. Ƙarfin bugun jini mafi girma ya dace da sarrafa kayan ƙarfe, yayin da ake amfani da bugun jini mai ƙarancin kuzari don gyaran saman.

②Aikace-aikacen Likita:
Ana amfani da na'urorin laser masu bugun zuciya sosai a fannin likitanci, musamman don tiyatar laser, maganin fata, da kuma maganin ido. Misali, na'urorin laser masu bugun zuciya masu ƙarfi sosai na iya mayar da kuzarin laser na musamman a kan ƙananan wurare don cire nama mai ciwo ko magance matsalolin ido.

③LiDAR da Nesa Mai nisa:
Fasahar LiDAR ta dogara ne akan na'urorin laser masu ƙarfin bugun jini masu ƙarfi don daidaita kewayon da kuma ɗaukar hoto. A cikin sa ido kan muhalli, tuƙi mai sarrafa kansa, da sa ido kan jiragen sama marasa matuƙa, girman kuzarin bugun yana shafar nisan ganowa da ƙudurin tsarin LiDAR kai tsaye.

④Binciken Kimiyya:
Na'urorin laser masu bugawa suma suna taka muhimmiyar rawa a gwaje-gwaje a fannin kimiyyar lissafi, sinadarai, da kuma ilmin halitta. Ta hanyar sarrafa kuzarin bugun jini daidai, masana kimiyya za su iya gudanar da bincike mai zurfi ta hanyar amfani da laser, hanzarta ƙwayoyin cuta, da kuma binciken sanyaya laser.

4. Hanyoyin Ƙara Makamashin Pulse

Hanyoyi da aka saba amfani da su don ƙara ƙarfin bugun laser sun haɗa da:

①Samun Matsakaicin Ingantawa:
Ta hanyar zaɓar hanyar samun riba mai dacewa da kuma inganta ƙirar ramin laser, za a iya ƙara ƙarfin fitarwa na laser.

②Ƙara Laser Mai Matakai Da yawa:
Amplifiers masu matakai da yawa na iya ƙara ƙarfin bugun laser a hankali don biyan buƙatun aikace-aikace daban-daban.

③Ƙara yawan wutar lantarki ko faɗin bugun jini:
Daidaita ƙarfin tuƙi ko faɗin bugun laser na iya haifar da ƙarin kuzarin bugun jini.

④Fasahar Matsa Pulse:
Ta amfani da dabarun matse bugun zuciya, ana iya rage tsawon lokacin bugun zuciya, yana ƙara ƙarfinsa da kuma fitar da ƙarin kuzari cikin ɗan gajeren lokaci.

5. Kammalawa

Makamashin bugun Laser muhimmin siga ne wanda ke tasiri kai tsaye ga aikin da aikace-aikacen laser a fannoni daban-daban. Tare da ci gaba da ci gaba a fasahar laser, lasers masu bugun za su sami fa'idodi masu yawa a masana'antu da yawa. Daga injinan da suka dace zuwa na'urorin gano nesa da kuma jiyya na likita, yawan makamashin da lasers masu bugun ke samarwa yana buɗe sabbin damammaki. Fahimtar mahimman ra'ayoyi game da makamashin bugun da abubuwan da ke tasiri a cikinsa na iya taimakawa wajen yin ƙarin zaɓin kimiyya yayin tsara da amfani da tsarin laser.
