The ojiji nke lasers

Okwu "laser" otú guzosie ike ná ndụ anyị, na ndị a ngwaọrụ eleghị anya maara ọ bụla okenye bi planet. The ojiji nke lasers aghọwo omenala na ihe fọrọ nke nta kwa ụbọchị. Ọ na-eji na ọtụtụ ebe nke mmadụ.

US physics arụ ọrụ na laabu ka ha mara. Lorenz kwuru nke bụ na ha na-enwe ike mụta nwa na-enwetụbeghị ụdị kasị doo ya. The laser ike 500 watts na 1,85 trillionov Mega joules nke UV radieshon. Chepụtara doo nwere a size of 2 mm n'obosara, ma ike ya karịrị nke a na-enwe niile ume iri ngwaọrụ ke United States, na-arụ ọrụ n'otu oge. laser okpomọkụ bụ 100 nde degrees, na ihe karịrị a center nke isi iyi nke ike - anyanwụ.

Gịnị bụ a laser? Nke a bụ isi iyi nke akpa radieshon, nke dabeere kpaliri emission nke ụmụ irighiri na atọm. Ọ na-agụnye ndị ahụ anya, infrared na ultraviolet àmà, ji nnọọ elu radieshon direction, nke bụ ya pụrụ iche ike.

Tee a dịgasị iche iche nke lasers. Ọ na-eji na ebe nke mmadụ ọrụ dị otú ahụ dị ka nkà mmụta ọgwụ, bayoloji, agha ụlọ ọrụ, ebe na na nkwukọrịta, ozi nchekwa, atụ w anya, ntule telivishọn, elu technology, na ọtụtụ ndị ọzọ. Ọkà mmụta sayensị taa nwere ekele na laser monochromatic ìhè nke ọ bụla wavelength. Nke a pụrụ ịbụ a na-aga n'ihu emission ụdịdị dị iche iche na a warara ma ọ bụ ultrashort usu.

Mara ụdị lasers:

- Gas;

- siri ike;

- mmiri mmiri.

The nwetụ usu mode na-arụ ọrụ rubi laser, ma na gaseous isi na-arụ ọrụ umi, n'ezie, gas. Ya atọm emepụta site electric orùrù usu.

E nwere okporo ọkụ lasers, nke na-aga n'ihu na ngwaọrụ. The radieshon ike nke a na-weere na ihe eletrik. E nwekwara gas-ike lasers. Ha bụ ndị dị ike, ndị nwere otu aha ndabere, ji a na-aga n'ihu ime ihe. Ha ụkpụrụ nke ime ihe dabeere na jụrụ usoro nke supersonic gas aga.

Mara ụdị lasers na-ekewa n'ime ọtụtụ ụdị dabere na ihe onwunwe na nke ha na-arụ ọrụ: e ji esiji ákwà, gas, metal Alụlụụ ma ọ bụ siri ike-ala.

Original oge a-enyocha mbara igwe na-eji laser ma na-ịtụnanya pụta. Ha kpebisiri ike kpọmkwem anya ka Ụwa satellite - Ọnwa, na e ji a ji obi ike nnwale, a rubi laser na nkuku reflectors. ọkà mmụta sayensị na-eji a uche laser teliskop zitere site na n'elu. Site oge nọrọ na ụzọ ọnwa na azụ, kpọmkwem anya kpebisiri.

Na nkà mmụta ọgwụ, na ojiji nke lasers bụ incredibly sara mbara. Na enyemaka ha laghachi ndị mmadụ na-ebi ndụ a jupụtara ndụ. Otu ihe atụ nwere ike arụmọrụ ekenịmde na retina n'oge nke kama a mkpa mee, ndị dọkịta na-eji ihe niile ahụ laser. Ke adianade do, akpa radieshon isi iyi na-iji na-emeso oké ọkpụkpụ unan, nakwa dị ka n'oge ịwa ahụ mgbe ọ na-achọrọ compound adọwa muscle anụ ahụ.

Ọkà na laser tuwizas nwere ohere ọhụrụ na protein nnyocha. Ọtụtụ-eji laser magnetisation na obi jụrụ ma ọ dị mkpa ụmụ irighiri iji ultralow okpomọkụ. Ọ mara iji lasers na anọ na, n'elu ọgwụgwọ, okpomọkụ omume na hardening nke ọla, na, ke adianade do, na mmepụta nke oge a na ngwá agha. Ihe atụ, na 2009, na American ụlọ ọrụ Northrop Grumman eguzobewo a siri ike-ala electric laser, onye ike bụ 100 kW. Development a chọrọ mbuso ikuku na ala zaa na mba agbachitere.
