Nhau - Nei Tiri Kushandisa ND: YAG Crystal seyewana svikiro muDPSS Laser?

Nyorera kune yedu Social Media for Prompt Post

Chii chinonzi laser kuwana svikiro?

A laser kuwana svikiro chinhu chinowedzera mwenje nekukasira kubuda. Kana maatomu epakati kana mamorekuru anofara kune akakwirira simba mazinga, vanogona kusundira mapikicha emamwe mawindogy kana achidzokera kune yakaderera simba mamiriro. Maitiro aya anowedzera mwenje achipfuura nepakati, iyo inokosha kuna Laser kushanda.

Ndeipi yakajairwa kuwana svikiro?

Iyo kuwana svikiro inogona kusiyana-siyana, kusanganisiramagasi, zvinwiwa (dhayi), solids.Solid-State Lasers, semuenzaniso, kazhinji inoshandisa makristasi senge nd: iyog (neodymium-dipped ytttrium aluminium garnet) kana magirazi akagadziriswa neisingawanzo-pasi zvinhu. Dye lasers shandisa organic dyes yakanyungudutswa mune solvent, uye gasi lasers anoshandisa magasi kana gasi musanganiswa.

Laser tsvimbo (kubva kuruboshwe kurudyi): Ruby, Alexandrite, Er: Yag, nd: Yag

The differences between Nd (Neodymium), Er (Erbium), and Yb (Ytterbium) as gain mediums

Kunyanya kuwirirana nekwavo kukwikwidza wavelength

Emberion wavelengths:

- Er: erbium inowanzo gumbura pa 1.55 μm, iri mundima yemaziso uye inobatsira kwazvo kune telecommunication application nekuda kwekudzikira kwekusimbisa (Gong et al., 2016).

- yb: ytterbium inowanzoburitsa kutenderera 1.0 kusvika ku1.1 μm, ichiita kuti iite kuti iite huwandu hwakawanda hwekushandisa, kusanganisira dzakakwirira-simba lasers uye amplifiers. YB inowanzoshandiswa seye sensitizer yeEr kuti uwedzere kushanda kweiyo er-dipped zvishandiso nekuendesa simba kubva kuYB to ER.

- ND: Neodymium-Didwed zvinhu zvinowanzo bvisa nguva zhinji 1.06 μm. ND: YAG, semuenzaniso, inozivikanwa nekubudirira kwayo uye inoshandiswa zvakanyanya mune ese maindasitiri uye ekurapa lasers (Yang et al., 2009).

Energy kuendesa michina:

- Er uye yb Co-doping: Iyo COPINS: DoPing of ER uye yb mune yedanho remuti inobatsira yekuwedzera kubvumirana mu 1.5-1.6 rangem YB inoita seyakanaka sensitizer yeEr nekubvisa pombi mwenje uye kuendesa simba kune er ions, inotungamira yakamisikidzwa kubuda mu telecommunication band. Iyi esimba kuendesa yakakosha kune iyo yekushanda kweEr-Dided Fiber Amplifiers (Edfa) (DK Vysokikh et Al., 2023).

- Nd: nd haawanzoda sensitizder sey yb in er-dosped system. Kubudirira kwaNdinobudirira kunobva pakunyorwa kwayo kwekunyora kwepombi.

Zvishandiso:

- Er:Zvikuruzvo zvinoshandiswa mu telecommunications nekuda kwekubuda kwayo pa1,55 μm, iyo inoenderana neyakaderera kurasikirwa kweSilica Optica Spical fibles. Er-Doped Goin Svikiro dzakakosha kune Optical Amplifiers uye Lasers muhurefu-Fiber Optication Expic yekutaurirana.

- yb:Inowanzoshandiswa muzvinyorwa zvepamusoro-soro nekuda kwehuremu hwayo hwakajeka hunobvumira kuti uwedzere diode pumping uye yakakwira simba rinobuda. YB-DEPPED zvinhu zvinoshandiswawo kusimudzira mashandiro eEr-Dided Systems.

- nd. ND: YAG Lasers inonyanya kukosheswa nekubudirira kwavo, simba, uye raisanganisira.

Nei takasarudza nd: yg seyewana yepakati mu dpss laser

A dpss laser rudzi rwe laser inoshandisa yakasimba-nyika kuwana pakati (saNig) yakamiswa neye semiconductor laser diode. Iyi tekinoroji inobvumira compact, inoshanda lasers inokwanisa kugadzira mitsipa yakakwirira-yemhando mune inoonekwa-kune-infrared spectrum. Chinyorwa chakadzama, iwe unogona kufunga nezvokutsvagurudza kuburikidza nemakwenzi ane mukurumbira wesainzi kana vaparidzi vekuongorora kwakazara paDPSS LASS LASS LASER TECTEMY.

ND: YAG inowanzoshandiswa seyakawana svikiro muSemiconductor-pumped laser modules nekuda kwezvikonzero zvakati, sezvakaratidzwa nezvidzidzo zvakasiyana:

1.high kunyorera uye Simba Kubuda. Izvi zvinoratidza kugona kwakanyanya uye kugona kweiyo simba rakakwirira
2.operational kuchinjika uye kuvimbika. Izvi zvinoratidza nd: yag's zvinoenderana uye kuvimbika seyakawana svikiro mune dzakasiyana laser zvikumbiro (Zhang et al., 2013).
3.Rgelange uye Beam mhando. Chidzidzo chacho chakataurwa chakawedzera kushanda ne 4,8 x 10 ^ 9 shots pasina kukuvara kwekukuvara, kuchengeta yakanaka kwazvo beam mhando (coyle et al., 2004).
4.highly inoshanda inoenderera-waveZvidzidzo zvakaratidza kuenderera mberi kweanopfuurira-wave (CW) kushanda kweND: YAG Lasers, ichiratidza kushanda kwavo seyakawana svikiro mune diode-pumped laser system. Izvi zvinosanganisira kuwana huwandu hwepamusoro hwekushandurwa kwekushandura uye kushamwaridzana nekusakwana, kuwedzera kupokana nekukodzera kweNN: Yag yekukwira-zvakanaka-kugona laser (zhu et al., 2013).

Iko kusanganiswa kwekubudirira kwakanyanya, kubudiswa kwemagetsi
