Kuchulukitsa kwamphamvu ndi mphamvu ya laser

Kuchulukitsa ndi kuchuluka kwakuthupi komwe timazolowera m'moyo wathu watsiku ndi tsiku, kachulukidwe kamalumikizana kwambiri ndi kachulukidwe kazinthu, formula ya zinthuzo ndi ρ = ​​ma / v Koma mphamvu zamagetsi ndi mphamvu za laser zimakhala zosiyana, apa zogawanika ndi malowo m'malo voliyumu. Mphamvu imalumikizananso ndi kuchuluka kwathu, chifukwa timagwiritsa ntchito magetsi tsiku lililonse, ndi, gawo la mapangidwe a mphamvu ndi w / m2, komanso mumunda wa laser, chifukwa malo a laser aser amagwera ndi ochepa, kotero w / cm2 amagwiritsidwa ntchito ngati gawo. Kuchulukitsa kwamphamvu kumachotsedwa pa lingaliro la nthawi, kuphatikiza mphamvu ndi kachulukidwe, ndipo gawo ndi J / CM2. Nthawi zambiri, ma angala opitilira amafotokozedwa pogwiritsa ntchito mphamvu, pomwemapira a ma lasersamafotokozeredwa pogwiritsa ntchito mphamvu zonse komanso kuchuluka kwa mphamvu.

Pamene laser imachita, kuchuluka kwa mphamvu nthawi zambiri kumatsimikiza ngati khomo loti liwonongeke, kapena kuthirira, kapena zinthu zina zochitira ziwonetsero zimafikiridwa. Tsimikizani ndi lingaliro lomwe limawoneka nthawi zambiri mukamaphunzira kulumikizana kwa aser ndi zinthu. Pakuphunzira kwa kampazi kwakanthawi (komwe kumatha kuonedwa ngati gawo la US), zomwe zikuwoneka ngati gawo la NS), ndipo ngakhale ultra-Starger (PSS oyambilira) nthawi zambiri amatengera lingaliro la mphamvu. Lingaliro ili, pamlingo wolumikizana, imayimira mphamvu yogwiritsira ntchito chandamale paderali, pankhani ya wosewerera wa gawo lomweli, kukambirana kumeneku ndi kwakukulu.

Palinso cholowa chake pamapangidwe a jekeseni wosakwatiwa wosakwatiwa. Izi zimapangitsanso kuti kafukufuku wa ma laser-atwork ovuta. Komabe, zida zamasiku ano zikusintha nthawi zonse, zokhala ndi mphamvu zochulukirapo, zobwereza zokhazokha, zomwe zimachitika mosinthasintha, ndipo zimafunikiranso kusintha kwamphamvu kwambiri. nthawi, osati malo). Komabe, zikuwonekeratu kuti mafunde enieni enieni sangakhale akona, funde, kapena ngakhale belu kapena gausian, ndipo ena amatsimikiziridwa ndi zinthu za laser yomwe, yomwe imapangidwa.

Kukhazikika kwamphamvu nthawi zambiri kumaperekedwa ndi kutalika kwa theka-kutalika komwe kumaperekedwa ndi oscilsoscope (kutalika kokwanira theka-mmakono wa Fwhm), zomwe zimatipangitsa kuwerengera mtengo wa kuchuluka kwa mphamvu, zomwe ndizokwera. Kutalika koyenera komanso kutalika kumayenera kuwerengedwa ndi kutalika kwake, kutalika kwa theka komanso m'lifupi. Sipanakhalepo kufunsa mwatsatanetsatane kuti mudziwe zamphamvu zodziwiratu. Chifukwa chake), kenako ndikuchulukitsidwa ndi mawu ogulitsa, ndipo mwatha.
