Isi ihenjirimara nke lasers

Ọgbọ nkelasersOzizi nke "radieshon na-enweghị ihe mberede na nke a na-akpali akpali" nke Einstein tụpụtara na 1916 bụ ntọala anụ ahụ nke oge asistemụ laserMmekọrịta dị n'etiti photon na atọm nwere ike ibute ụdị usoro mgbanwe atọ: mmịpụta mkpali, mmịpụta mberede, na mmịpụta mkpali.

Isi ihe dị na lasers bụ:

1. Ezi ntụzịaka: Ebe ọ bụ na naanị ìhè ọkụ na-agbasa n'akụkụ oghere resonant nwere ike ịmepụta oscillation na mmụba na-aga n'ihu, mmepụta laser sitere na laser nwere obere ọdịiche dị iche iche Angle na ezigbo ntụzịaka, na-eme ka ọ bụrụ isi iyi ìhè dị mma.

2. Ọkụ dị elu: N'ihi ụzọ ya dị mma, ike laser dị n'ime mbara igwe, si otú a na-eme ka o nwee ike dị elu. Ọkụ anyanwụ na-enwu ihe dị ka 100W/cm². Ọkụ nke laser helium-neon nwere ike nke ọtụtụ milliwatts nwere ike ịdị elu karịa nke anyanwụ. Laser nke na-arụ ọrụ na pulsed

3. Ezigbo monochromaticity: N'ihi na photons nke radieshon kpaliri na-emepụta nwere otu ugboro ma nwee oke site na oghere resonant, naanị ìhè nke ogologo ebili mmiri doro anya nwere ike ịgbagharị ma wepụta ya. Ya mere, lasers nwere monochromaticity dị mma.

4. Ezigbo njiko: Ìhè nkịtị nke radieshon na-apụta bụ ìhè na-adịghị agbanwe agbanwe, ebe àgwà nke ìhè nke radieshon na-akpali akpali na-eme ka laser nwee njikọ dị mma. Isi ihe anọ a na-enye usoro nchọpụta ọhụrụ na teknụzụ njirimara onyonyo maka ọgwụ na bayoloji.
