Mu tekinoroji yemazuva ano yelaser, ma diode pumping modules ave nzvimbo yakanaka yekupomba ma solid-state nema fiber lasers nekuda kwekushanda kwawo kwakanyanya, kuvimbika, uye dhizaini yavo diki. Zvisinei, chimwe chezvinhu zvakakosha zvinokanganisa mashandiro avo ekubuda uye kugadzikana kwesystem ndiko kufanana kwekugoverwa kwegain mukati me pump module.
1. Chii chinonzi Gain Distribution Uniformity?
Muma diode pumping modules, ma laser diode bars akawanda akarongwa mu array, uye pump light yavo inoendeswa kune gain medium (yakadai seYb-doped fiber kana Nd:YAG crystal) kuburikidza ne optical system. Kana simba rekugoverwa kwepombi light risina kuenzana, zvinotungamira kune asymmetric gain mune medium, zvichikonzera:
①Hunhu hwemwenje we laser hwakaderera
②Kuderedzwa kwekushanda zvakanaka kwesimba remagetsi
③Kuwedzera kwekushushikana kwekupisa uye kuderedzwa kwehupenyu hwehurongwa
④Njodzi yakakura yekukuvara kwemaziso panguva yekushanda
Saka, kuwana kufanana kwenzvimbo mukugoverwa kwechiedza chepombi chinangwa chakakosha chehunyanzvi mukugadzira nekugadzira mamodule epombi.
2. Zvikonzero Zvinowanzoita Kuti Kusave Nekuwana Kwakafanana
①Kusiyana kweChip Emission Power
Machipisi eLaser diode anoratidza shanduko dzesimba. Pasina kurongeka kana muripo wakakodzera, misiyano iyi inogona kutungamira pakusimba kwepombi munzvimbo yaunoda.
②Zvikanganiso muCollimation uye Focusing Systems
Kusarongeka kana zvikanganiso muzvikamu zve optical (semuenzaniso, ma FAC/SAC lenses, ma microlens arrays, fiber couplers) zvinogona kukonzera kuti zvikamu zve beam zvibve pane chinangwa chaunoda, zvichiita kuti pave nenzvimbo dzinopisa kana nzvimbo dzisina kusimba.
③Mhedzisiro yeGradient yeThermal
Malaser eSemiconductor anonyanya kukanganiswa nekupisa. Magadzirirwo asina kunaka eheatsink kana kutonhora kusina kuenzana zvinogona kukonzera kutenderera kwewavelength pakati pemachipisi akasiyana, zvichikanganisa kushanda zvakanaka kwekubatanidza uye kugadzikana kwezvinobuda.
④Dhizaini Isina Kukwana Yekuburitsa Fiber
Mumagadzirirwo emagetsi anoburitsa fiber kana beam-combining, marongerwo asina kunaka emagetsi anogonawo kukonzera kupararira kwechiedza chepombi chisina kufanana mu gain medium.
3. Matekiniki Ekuvandudza Kuwana Kufanana
①Kuronga Machipisi uye Kufananidza Simba
Chengetedza nemazvo uye unganidza machipisi e-laser diode kuti uve nechokwadi chekuti simba rinobuda rinowirirana mukati memodule yega yega, uchideredza kupisa kwakanyanya munzvimbo yako uye kuwedzera nzvimbo dzinopisa.
②Dhizaini Yemaziso Yakagadziridzwa
Shandisa magirazi asingashandisi mifananidzo kana magirazi akafanana (semuenzaniso, ma microlens arrays) kuti uvandudze kupindirana kwemwenje uye kutarisisa kwakarurama, nokudaro uchideredza chimiro chemwenje wepombi.
③Kutarisirwa Kwekupisa Kwakawedzerwa
Shandisa zvinhu zvinofambisa kupisa zvakanyanya (semuenzaniso, CuW, CVD diamond) uye nzira dzakafanana dzekudzora kupisa kuti uderedze kuchinja-chinja kwekupisa kubva kuchip kuenda kuchip uye kuchengetedza simba rakasimba rekubudisa.
④Kubatanidzwa kweChiedza neKusimba kweChiedza
Isa ma diffuser kana zvinhu zvinoumba mwenje munzira yepombi kuti uwane kupararira kwakaenzana kwechiedza munzvimbo iri pakati penzvimbo inobuda chiedza.
4. Kukosha Kunoshanda Mumashandisirwo Enyika Chaiyo
Mumasisitimu emhando yepamusoro elaser—zvakaita sekugadzirisa maindasitiri nemazvo, kusarudzwa kwemauto ne laser, kurapwa, uye kutsvagurudza kwesainzi—kugadzikana uye kunaka kwemwaranzi yelaser zvinokosheswa zvikuru. Kugoverwa kwekuwedzera kusina kufanana kunokanganisa zvakananga kuvimbika uye kururama kwesystem, kunyanya mune zvinotevera:
①MaLaser ane simba guru: Anodzivirira kuzara kwenzvimbo kana mhedzisiro isiri yemutsara
②Ma amplifiers e fiber laser: Anoderedza kuunganidza kwe ASE (Amplified Spontaneous Emission)
③LIDAR uye masisitimu ekutsvaga nzvimbo: Inovandudza kurongeka kwekuyera uye kudzokorora
④MaLaser ekurapa: Inovimbisa kutonga kwesimba kwakaringana panguva yekurapwa
5. Mhedziso
Kufanana kwekugoverwa kwekuwedzera kungave kusiri iyo parameter inonyanya kuoneka yepombi module, asi yakakosha pakushandisa simba rakavimbika remasisitimu elaser anoshanda zvakanyanya. Sezvo kudiwa kwemhando yelaser uye kugadzikana kuri kuramba kuchikwira, vagadziri vemapombi module vanofanira kugadzirisa"kutonga kwakafanana""senzira huru—kugara uchigadzirisa kusarudzwa kwemachipisi, dhizaini yemagadzirirwo, uye nzira dzekupisa kuti zvipe masosi elaser akavimbika uye anowirirana kune mamwe mashandisirwo ari pasi.
Une shungu dzekuziva kuti tingagadzirisa sei kuenzana kwesimba remapombi edu? Taura nesu nhasi kuti udzidze zvakawanda nezvemhinduro dzedu nerutsigiro rwehunyanzvi.
