Chii chinonzi Laser Gain Medium?

Nzira yekuwedzera chiedza inonzi laser gain medium imhando yezvinhu zvinowedzera chiedza kuburikidza nekuburitswa kwesimba. Kana maatomu kana mamorekuru echinhu chacho akawedzera simba, anogona kuburitsa maphoton ewavelength yakati kana achidzokera kusimba rakaderera. Maitiro aya anowedzera chiedza chinopfuura nepakati pechinhu ichi, chinova chinhu chakakosha pakushanda kwelaser.

Ndeipi Nzira Yekuwana Mari Yakajairika?

Nzira yekuwana nayo mari inogona kusiyana, kusanganisiramagasi, zvinwiwa (dhayi), zvakasimba(makristaro kana magirazi akaiswa maion esimbi asina kugadzirwa zvakanaka kana kuti esimbi inoshanduka), uye masemiconductor.MaLaser emhando yakasimbasemuenzaniso, vanowanzo shandisa makristaro akadai seNd: YAG (Neodymium-doped Yttrium Aluminum Garnet) kana magirazi akaiswa zvinhu zvisingawanzoitiki. Malaser edhayi anoshandisa madhayi eorganic akanyungudutswa muzvinonyungudutsa, uye malaser egasi anoshandisa magasi kana musanganiswa wegasi.

Rodhi dzeLaser (kubva kuruboshwe kuenda kurudyi): Ruby, Alexandrite, Er:YAG, Nd:YAG

Musiyano uripo pakati peNd (Neodymium), Er (Erbium), uye Yb (Ytterbium) senzira dzekuwana masero

zvinonyanya kuenderana nema wavelengths azvo ekubuda, nzira dzekufambisa simba, uye mashandisirwo azvo, kunyanya kana tichitarisa zvinhu zve laser zvakaiswa doped.

Mafungu Emhepo:

- Er: Erbium inowanzo buritsa simba pa1.55 µm, iri munzvimbo isingakuvadzi maziso uye inobatsira zvikuru pakushandisa nharembozha nekuda kwekurasikirwa kwayo mufiber dzemaziso (Gong et al., 2016).

- Yb: Ytterbium inowanzoburitsa 1.0 kusvika 1.1 µm, zvichiita kuti ive yakakodzera kushandiswa kwakasiyana-siyana, kusanganisira ma laser ane simba guru uye ma amplifiers. Yb inowanzo shandiswa senzira yekukurudzira Er kuti iwedzere kushanda zvakanaka kwemidziyo yakatorwa neEr nekutumira simba kubva kuYb kuenda kuEr.

- Nd: Zvinhu zvakasanganiswa neNeodymium zvinowanzoburitsa 1.06 µm. Semuenzaniso, Nd:YAG inozivikanwa nekushanda kwayo zvakanaka uye inoshandiswa zvakanyanya muma laser eindasitiri nekurapa (Y. Chang et al., 2009).

Maitiro Ekufambisa Simba:

- Er naYb Co-doping: Kubatanidzwa kweEr naYb muchinhu chinogamuchira mhepo kunobatsira pakuwedzera kuburitswa kwemhepo iri pakati pe1.5-1.6 µm. Yb inoshanda senzira yekusimbisa simba reEr nekupinza chiedza chepombi uye kuendesa simba kumaEr ions, zvichikonzera kuburitswa kwesimba munharembozha. Kufambiswa kwesimba uku kwakakosha pakushanda kweEr-doped fiber amplifiers (EDFA) (DK Vysokikh et al., 2023).

- Nd: Nd haiwanzo da sensitizer yakaita seYb mumasisitimu ane Er-doped. Kushanda zvakanaka kweNd kunobva mukupinza kwayo zvakananga chiedza chepombi uye kubuda kwayo kunotevera, zvichiita kuti ive nzira iri nyore uye inoshanda ye laser gain.

Mashandisirwo:

- Er:Inonyanya kushandiswa mukutaurirana nekuda kwekubuda kwayo pa1.55 µm, izvo zvinoenderana nekudzikira kudiki kwe silica optical fibers. Er-doped gain mediums yakakosha kune optical amplifiers uye lasers mumasisitimu ekukurukurirana e fiber optic ari kure.

- Yb:Inowanzoshandiswa mumashandisirwo ane simba guru nekuda kwechimiro chayo chemagetsi chiri nyore chinoita kuti ikwanise kupomba diode zvakanaka uye kuburitsa simba rakawanda. Zvinhu zvakasanganiswa neYb zvinoshandiswawo kusimudzira mashandiro emasystem akasanganiswa neEr.

- Nd: Yakakodzera kushandiswa kwakasiyana-siyana, kubva pakucheka nekubatanidza maindasitiri kusvika kuma laser ekurapa. Ma laser eNd:YAG anokosheswa zvikuru nekuda kwekushanda kwawo zvakanaka, simba, uye kushanduka-shanduka.

Sei takasarudza Nd:YAG senzira yekuwana simba muDPSS laser?

DPSS laser rudzi rwelaser inoshandisa solid-state gain medium (yakaita seNd: YAG) inopombwa ne semiconductor laser diode. Iyi tekinoroji inobvumira ma laser akamanikana, anoshanda zvakanaka anokwanisa kugadzira mwenje wemhando yepamusoro mu vis-to-infrared spectrum. Kuti uwane chinyorwa chakadzama, ungafunga nezvekutsvaga muma database esainzi ane mukurumbira kana vaburitsi kuti uwane wongororo dzakakwana pa DPSS laser technology.

Nd:YAG inowanzoshandiswa senzira yekuwana simba mumamodule elaser anopumpwa ne semiconductor nekuda kwezvikonzero zvakasiyana-siyana, sezvakaratidzwa nezvidzidzo zvakasiyana-siyana:

1.Kushanda Kwakanaka Kwazvo uye Simba Rekubuda: Dhizaini uye kutevedzera kwemodule yelaser yeNd:YAG ine diode side-pumped kwakaratidza kushanda zvakanaka, nelaser yeNd:YAG ine diode side-pumped inopa avhareji yesimba re220 W uku ichichengetedza simba risingaperi pakurova kwemoyo muhuwandu hwakawanda hwema frequency. Izvi zvinoratidza kushanda zvakanaka uye mukana wekuti malaser eNd:YAG abudise simba rakawanda kana achipombwa nema diode (Lera et al., 2016).
2. Kuchinjika Kwekushanda uye Kuvimbika: Zviumbwa zveNd:YAG zvakaratidzwa kuti zvinoshanda zvakanaka pahurefu hwakasiyana-siyana hwema wavelength, kusanganisira hurefu hwakachengeteka pamaziso, zvine simba guru re optical-to-optical. Izvi zvinoratidza kushanduka-shanduka uye kuvimbika kweNd:YAG senzira yekuwana simba mumashandisirwo akasiyana elaser (Zhang et al., 2013).
3. Hurefu hwenguva refu uye Beam Quality: Tsvagiridzo pamusoro peraser yeNd:YAG inoshanda zvakanyanya, inopombwa ne diode, yakasimbisa kugara kwayo kwenguva refu uye kushanda kwayo nguva dzose, zvichiratidza kukodzera kweNd:YAG pamashandisirwo anoda masosi eraser akasimba uye akavimbika. Chidzidzo ichi chakashuma kushanda kwenguva refu nemashoti anopfuura 4.8 x 10^9 pasina kukuvara kwemaziso, zvichichengetedza kunaka kwemwaranzi (Coyle et al., 2004).
4. Kushanda Kwakanaka Kwazvo Kuenderera Mberi-Mafungu:Zvidzidzo zvakaratidza kushanda zvakanaka kwazvo kwema laser eNd:YAG (Nd:YAG lasers) eNd:YAG, zvichiratidza kushanda kwawo senzira yekuwana ruzivo muma laser systems e diode-pumped. Izvi zvinosanganisira kuwana high optical conversion efficiency uye slope efficiencies, zvichiratidzawo kukodzera kweNd:YAG kuma applications e high-efficiency laser (Zhu et al., 2013).

Kubatanidzwa kwekushanda nesimba, simba rinobuda, kuchinjika kwekushanda, kuvimbika, kugara kwenguva refu, uye kunaka kwemwenje wepamusoro kunoita kuti Nd:YAG ive nzira inodiwa yekuwedzera simba mumamodule elaser anopumirwa ne semiconductor kune akasiyana mashandisirwo.
