Gịnị bụ Optical Pumping na Laser?

Ụdị Lasers Optically Pumped

1. Lasers siri ike nke nwere ihe mkpuchi Doped

· Nchịkọta:Laser ndị a na-eji ihe na-egbochi ọkụ eletrik ma na-adabere na ọkpọkọ anya iji mee ka ion ndị na-arụ ọrụ na laser nwee ike. Ihe atụ a na-ahụkarị bụ neodymium na laser YAG.

·Nnyocha Na-adịbeghị Anya:Nnyocha nke A. Antipov na ndị otu ya mere na-atụle laser siri ike nke dị nso na IR maka mgbapụta anya spin-exchange. Nnyocha a na-egosi ọganihu dị na teknụzụ laser siri ike, ọkachasị na ụdị infrared dị nso, nke dị oke mkpa maka ngwa dịka onyonyo ahụike na nkwukọrịta.

Ịgụkwu Ihe:Laser siri ike nke dị nso na IR maka mgbapụta anya Spin-Exchange

2. Laser Semiconductor

·Ozi Izugbe: Dịka ọ na-adịkarị, a na-eji ọkụ eletrik emepụta laser semiconductor, ha nwekwara ike irite uru site na mgbapụta anya, ọkachasị n'ọrụ ndị chọrọ nnukwu ìhè, dịka Laser Mmiri Elu Okpomọkụ nke Vertical External Cavity (VECSELs).

·Mmepe Ndị Na-adịbeghị Anya: Ọrụ U. Keller na combs optical frequency combs sitere na ultrafast solid-state na semiconductor lasers na-enye nghọta banyere mmepụta nke combs frequency combs kwụsiri ike site na diode-pumped solid-state na semiconductor lasers. Mmepe a dị mkpa maka ojiji na metrology optical frequency metrology.

Ịgụkwu Ihe:Ngwakọta ugboro ole anya sitere na laser siri ike na semiconductor lasers

3. Laser gas

·Ịkpọpụta ọkụ n'ime laser gas: Ụfọdụ ụdị laser gas, dị ka laser alkali vapor, na-eji mgbapụta anya. A na-ejikarị laser ndị a eme ihe n'ọrụ ndị chọrọ isi iyi ọkụ nwere ihe pụrụ iche.

Isi mmalite maka mgbapụta anya

Oriọna mwepụtaA na-ejikarị oriọna ndị a na-akpọ "induction languages" eme ihe n'ụdị laser ndị a na-akpọ "induction languages" maka ike dị elu na obosara ha. YA Mandryko na ndị otu ya mepụtara ụdị ike nke mmepụta mgbapụta arc na oriọna xenon nke na-arụ ọrụ na mgbasa ozi na-arụ ọrụ nke laser siri ike. Ụdị a na-enyere aka ime ka arụmọrụ nke oriọna mgbapụta mkpali dịkwuo mma, nke dị mkpa maka ọrụ laser dị irè.

Diode laser:A na-eji lasers nke diode pumped eme ihe, laser diodes na-enye uru dị ka arụmọrụ dị elu, obere nha, na ikike ịhazi ya nke ọma.

Ọgụgụ ọzọ:Kedu ihe bụ diode laser?

Ọkụ ọkụỌkụ ọkụ bụ isi iyi ọkụ siri ike, nke sara mbara nke a na-ejikarị eme ihe maka ịpịpụta laser siri ike, dị ka laser ruby ​​ma ọ bụ Nd:YAG. Ha na-enye nnukwu ọkụ nke na-akpali mgbasa ozi laser.

Oriọna Arc: Dịka oriọna ọkụ mana e mere ya maka ịrụ ọrụ na-aga n'ihu, oriọna arc na-enye ìhè siri ike mgbe niile. A na-eji ha eme ihe ebe achọrọ ọrụ laser na-aga n'ihu (CW).

LED (Diode ndị na-ewepụta ìhè): Ọ bụ ezie na ọ bụghị ihe a na-ahụkarị dịka diode laser, enwere ike iji LEDs mee ihe maka mgbapụta anya n'ọtụtụ ngwa nwere obere ike. Ha bara uru n'ihi ogologo ndụ ha, ọnụ ahịa ha dị ala, na nnweta ha n'ọtụtụ ebili mmiri dị iche iche.

Ìhè anyanwụ: N'ụfọdụ usoro nnwale, ejirila ìhè anyanwụ dị ka isi iyi mgbapụta maka lasers ndị a na-eji ike anyanwụ eme ihe. Usoro a na-eji ike anyanwụ eme ihe, na-eme ka ọ bụrụ isi iyi mmeghari ohuru na nke dị ọnụ ala, ọ bụ ezie na ọ naghị achịkwa ma dịkwa oke ike ma e jiri ya tụnyere isi iyi ọkụ arụrụ arụ.

Diodes laser nke eriri jikọtara ọnụ: Ndị a bụ diode laser ejikọtara na eriri anya, nke na-enye ọkụ mgbapụta ahụ nke ọma na igwe laser. Usoro a bara uru karịsịa na laser eriri na n'ọnọdụ ebe nnyefe ọkụ mgbapụta ziri ezi dị oke mkpa.

Laser ndị ọzọ: Mgbe ụfọdụ, a na-eji otu laser agba nke ọzọ. Dịka ọmụmaatụ, enwere ike iji laser Nd: YAG ugboro ugboro okpukpu abụọ iji gbapụta agba laser. A na-ejikarị usoro a eme ihe mgbe achọrọ ogologo ebili mmiri kpọmkwem maka usoro mgbapụta nke na-adịghị mfe inweta site na isi mmalite ọkụ nkịtị.
