Machitidwe ofunikira a laser osapeza

Kodi ndi mikhalidwe yofunika ya chiyani ya laser?

Laser amapeza ndalama zapakatikati, omwe amadziwikanso kuti laser akugwira ntchito, amatanthauza zinthu zomwe zagwiritsidwa ntchito potengera tinthu tating'onoting'ono tomwe timayambitsa tinthu tating'onoting'ono tomwe timalimbikitsidwa kuti mukwaniritse zowunikira. Ndi gawo limodzi la laser, kunyamula ma atomu ambiri kapena ma atomu awa kapena mamolekyulu omwe ali pansi pa mphamvu zakunja, amatha kusintha ma radiation, komanso kudzera mukuwala kwa laser. Laser apeza sing'anga akhoza kukhala olimba, amadzimadzi, mpweya kapena semiconductor.
M'malo olimba-boma, omwe amagwiritsidwa ntchito kwambiri ndi makristal omwe amapezeka ndi ma ion padziko lapansi, monga ND: makristal, yvo4 nthawi zambiri amagwiritsidwa ntchito ngati media. Lasers a Lasers amagwiritsa ntchito gasi ngati sing'anga ya kaboni dayokisaidi la ma lasitala a kaboni dayobor, ndi helium ndi son laseri ku Helium.Semiconductor LasersGwiritsani ntchito zida za Semiconductor monga momwe mungaperekedwera sing'anga, monga gallium warnide (Gaas).
Makhalidwe ofunikira a laser amapeza sing'anga kuphatikiza:
Kupanga kwamphamvu kwa mphamvu: maatomu kapena mamolekyulu opezeka sing'anga ayenera kukhala ndi mphamvu yoyenera kuti akwaniritse kuchuluka kwa kuchuluka kwa mphamvu zakunja. Izi nthawi zambiri zimatanthawuza kuti mphamvu yamagetsi pakati pa mphamvu zapamwamba komanso zotsika zimafunikira kufanana ndi mphamvu ya phulusa.

Njira Zosintha: maatomu kapena mamolekyulu odziwika bwino ayenera kukhala ndi kusintha kwa kusintha kwa kusintha kwa masinthidwe omwe amatulutsa zithunzi zogwirizana panthawi yodala ma radiation. Izi zimafuna kuti sing'anga kukhala ndi luso lalikulu komanso kutaya kochepa.
Kukhazikika kwamatenthedwe ndi mphamvu yamagetsi: Ntchito zothandiza, sing'anga amafunika kuthana ndi zotupa zapamwamba komanso zotuluka, motero zimafunikira kukhala ndi mphamvu yabwino yamagetsi komanso mphamvu yamakina.
Khalidwe lowoneka bwino: Kuchuluka kwa kuchuluka kwa zomwe zimapezeka sing'anga ndikofunikira pakuchita kwa laser. Imafunika kukhala ndi kupanikizika kwambiri komanso kutaya kochepa kwambiri kuti mutsimikizire mtundu ndi kukhazikika kwa mtengo wa laser. Kusankha kwa laser kumatenga ndalama kumadalira zofunikira zalaser, kugwira ntchito kwamphamvu, mphamvu yotulutsa ndi zinthu zina. Pofuna kukonza zinthuzo ndi kapangidwe ka zomwe zimapezeka sing'anga, magwiridwe antchito ndi luso la laser ingakonzekere.
