4. Intracavity modulation technology, jiri ya tụnyere mpụga modulation, intracavity modulation nwere ike ọzọ rụọ ọrụ nke ọma ike dị elu ike, elu ike.pulse laser. Ndị a bụ usoro mgbanwe intracavity anọ a na-ahụkarị:
a. Enweta mgbanwe site n'ike n'ike modulating mgbapụta isi iyi, nweta ọkara urughuru nọmba inversion na uru ọnụọgụ na-ngwa ngwa guzosie ike, na-agafere kpaliri radieshon ọnụego, na-akpata a nkọ abawanye na photons na oghere na ọgbọ nke mkpụmkpụ usu laser. Usoro a bụ nke a na-ahụkarị na lasers semiconductor, nke nwere ike ịmepụta pulses site na nanoseconds ruo iri iri nke picoseconds, na ọnụ ọgụgụ ugboro ugboro nke ọtụtụ gigahertz, a na-ejikwa ya n'ọhịa nke nkwurịta okwu anya na ọnụ ọgụgụ nnyefe data dị elu.
Q mgba ọkụ (Q-switching) Q switches na-egbochi nzaghachi anya anya site na iwebata nnukwu mfu n'ime oghere laser, na-ekwe ka usoro mgbapụta na-emepụta ihe na-eme ka ọnụ ọgụgụ mmadụ gbanwee ihe karịrị ọnụ ụzọ, na-echekwa ike dị ukwuu. Na-esote, mfu na oghere ahụ na-ebelata ngwa ngwa (ya bụ, uru Q nke oghere ahụ na-abawanye), na nzaghachi anya na-atụgharị ọzọ, nke mere na a na-ahapụ ike ahụ echekwara n'ụdị ultra-short high-intensity pulses.
c. Mkpọchi ọnọdụ na-emepụta ultra-short pulses nke picosecond ma ọ bụ ọbụna femtosecond larịị site na ịchịkwa mmekọrịta nke oge n'etiti ụdị ogologo ogologo dị iche iche na oghere laser. A na-ekewa teknụzụ mkpọchi mode na mkpọchi ọnọdụ na-agafe agafe na mkpọchi ọnọdụ na-arụ ọrụ.
d. Ntupu oghere Site na ịchekwa ike n'ime foton na resonator, na-eji enyo oghere dị ala na-efunahụ iji kechie foton nke ọma, na-ejigide ọnọdụ mfu dị ala n'ime oghere ruo oge ụfọdụ. Mgbe otu okirikiri njem gachara, a na-awụpụ pulse siri ike site na oghere site na ịgbanye ngwa ngwa ime oghere dị n'ime oghere, dị ka ihe nrụnye acousto-optic modulator ma ọ bụ ihe mkpuchi electro-optic, a na-ewepụtakwa laser pulse dị mkpụmkpụ. E jiri ya tụnyere Q-switching, oghere oghere nwere ike idowe obosara pulse nke ọtụtụ nanoseconds na ọnụego nkwughachi dị elu (dịka ọtụtụ megahertz) ma nye ohere maka ume pulse dị elu, karịsịa maka ngwa ndị chọrọ nnukwu nkwughachi ọnụego na obere mkpọ. Ejikọtara ya na usoro ọgbọ ndị ọzọ pulse, ike pulse nwere ike ime ka ọ dịkwuo mma.
Pulse akara nkelaserbụ usoro dị mgbagwoju anya ma dị mkpa, nke gụnyere njikwa obosara pulse, njikwa ugboro ugboro na ọtụtụ usoro modulation. Site na nhọrọ ezi uche dị na ya na ntinye nke ụzọ ndị a, a pụrụ imezi arụmọrụ laser nke ọma iji gboo mkpa nke ọnọdụ ngwa dị iche iche. N'ọdịnihu, na-aga n'ihu na-apụta nke ihe ọhụrụ na teknụzụ ọhụrụ, nkà na ụzụ nchịkwa nke lasers ga-ebute ọganihu ndị ọzọ, ma kwalite mmepe nketeknụzụ laserna ntụziaka nke elu nkenke na wider ngwa.
