LPT-11 Serial Experiment na Semiconductor Laser

Nkọwa

Site na ịlele ike, voltaji na nke ugbu a nke semiconductor laser, ụmụ akwụkwọ ahụ nwere ike ịghọta njirimara ọrụ nke semiconductor laser n'okpuru nrụpụta na-aga n'ihu. A na-eji nyocha nyocha ọtụtụ multichannel mee ihe iji hụ nsị nke ọkụ ọkụ nke semiconductor laser mgbe ọnye ogwu ahụ na-erughị ọnụ ụzọ mbata na ngbanwe mgbanwe ahịrị nke oscillation laser mgbe nke ugbu a karịa ọnụ ụzọ mbata.

Laser n'ozuzu mejuputara uzo ato
(1) Laser na-arụ ọrụ ọkara
Ọgbọ nke laser ga-ahọrọ ndị na-arụ ọrụ kwesịrị ekwesị, nke nwere ike ịbụ gas, mmiri mmiri, siri ike ma ọ bụ semiconductor. Na ụdị usoro a, enwere ike ịmegharị ọnụ ọgụgụ nke ihe ahụ, nke bụ ọnọdụ dị mkpa iji nweta laser. N'ụzọ doro anya, ịdị adị nke ike metastable bara ezigbo uru na nghọta nke ntụgharị ọnụọgụgụ. Ka ọ dị ugbu a, enwere ihe dịka 1000 na-arụ ọrụ mgbasa ozi, nke nwere ike ịmepụta ọtụtụ ntụgharị laser site na VUV ruo infrared tere aka.
(2) Ntughari ume
Iji mee ka ntughari nke ọnụ ọgụgụ ahụ na-apụta na onye na-arụ ọrụ, ọ dị mkpa iji ụfọdụ ụzọ iji kpalie usoro atomiki iji mee ka ọnụ ọgụgụ dị elu na ọkwa dị elu. Ke ofụri ofụri, gas orùrù nwere ike iji kpalie dielectric atọm site elektrọn na kinetic ike, nke a na-akpọ eletriki excitation; A pụkwara iji ọkụ ọkụ na-ekpo ọkụ na-arụ ọrụ, nke a na-akpọ ngwa anya ngwa ngwa; thermal excitation, chemical excitation, wdg A na-ahụ ụzọ dị iche iche dị iche iche dị ka mgbapụta ma ọ bụ mgbapụta. Iji nweta mmepụta laser na-aga n'ihu, ọ dị mkpa ịkwanye na-aga n'ihu iji mee ka ọnụ ọgụgụ nke ahụ na ọkwa dị elu karịa nke ahụ na ọkwa ala.
(3) oghere na-ada ụda
Na ihe eji arụ ọrụ kwesịrị ekwesị na isi mmalite, enwere ike ịmegharị nọmba nke mkpụrụ ahụ, mana ike nke radieshon kpalitere na-esighi ike, yabụ enweghị ike itinye ya n'ọrụ. Ya mere, ndị mmadụ na-eche banyere iji ngwa anya resonator na-agbasa. Ihe a na-akpọ optical resonator bụ n'ezie enyo abụọ nwere ngosipụta dị elu arụnyere na ihu na ihu na laser abụọ. Otu fọrọ nke nta ka ngụkọta echiche, ndị ọzọ na-akasị na-egosipụta na a obere ebute site ná, nke mere na laser nwere ike emitted site na enyo. Ìhè ahụ laghachiri azụ na-arụ ọrụ na-aga n'ihu na-ebute ụzarị ọkụ ọhụrụ, na-amụbawanye ọkụ. Ya mere, ìhè oscillates azụ na-apụta na resonator, na-eme ka a yinye mmeghachi omume, nke a na-adịkwu ka nnukwu, na-amị a siri ike laser mmepụta si n'otu njedebe nke ele mmadụ anya n'ihu mirror ngosi.
