Mune yemazuva ano laser tekinoroji, diode kupomba modules yave yakanakira pombi sosi yeakasimba-nyika uye faibha lasers nekuda kwekuita kwavo kwakanyanya, kuvimbika, uye compact dhizaini. Nekudaro, chimwe chezvinhu zvakakosha zvinokanganisa maitiro avo ekubuda uye kugadzikana kwehurongwa ndiko kufanana kwekuwana kugovera mukati mepombi module.
1. Chii chinonzi Gain Distribution Uniformity?
Mune diode kupomba mamodule, akawanda laser diode mabara akarongedzerwa muhurongwa, uye mwenje wavo wepombi unounzwa mune yekuwana yepakati (yakadai seYb-doped fiber kana Nd: YAG crystal) kuburikidza neoptical system. Kana kugoverwa kwesimba kwepombi mwenje kusingaenzaniswi, zvinotungamira kune asymmetric kuwana mukati, zvichikonzera:
①Yakaderedzwa beam kunaka kweiyo laser kubuda
②Yakaderedzwa simba rekushandura simba
③Kuwedzera kushushikana kwekupisa uye kuderedzwa kwehupenyu hwehurongwa
④Ngozi yepamusoro yekukuvara kwemaziso panguva yekushanda
Naizvozvo, kuwana kufanana kwenzvimbo mukugovera mwenje wepombi chinhu chakakosha tekinoroji mukugadzira pombi module uye kugadzira.
2. Zvikonzero Zvinowanzokonzera Kugovera Kusina Kufanana-Kufanana
①Kusiyana kweChip Emission Power
Laser diode machipisi anogara anoratidza masimba akasiyana. Pasina kurongeka kwakafanira kana muripo, misiyano iyi inogona kutungamira mukusawirirana kwepombi munzvimbo yese inotarirwa.
②Zvikanganiso muCollimation uye Focusing Systems
Kukanganisa kana kukanganisa muzvikamu zvemaziso (semuenzaniso, FAC/SAC lenses, microlens arrays, fiber couplers) zvinogona kukonzera kuti zvikamu zvedanda zvitsauke kubva pane zvakarongwa, kugadzira hotspots kana nzvimbo dzakafa.
③Thermal Gradient Migumisiro
Semiconductor lasers inonyanya kunzwa kune tembiricha. Kusakwana heatsink dhizaini kana kutonhora kusina kuenzana kunogona kukonzera wavelength kudonha pakati pemachipi akasiyana, zvichikanganisa kubatanidza kushanda zvakanaka uye kubuda kuenderana.
④Isina kukwana Fiber Output Design
Mune akawanda-musimboti faibha kana danda-kusanganisa zvinobuda zvimiro, zvisina kufanira musimboti dhizaini inogona zvakare kukonzera isina-uniform pombi mwenje kugovera mune yekuwana medium.
3. Matekiniki eKuvandudza Kuwana Kufanana
①Chip Sorting uye Simba Matching
Chaizvo skrini uye neboka laser diode machipisi kuti ive nechokwadi chakafanana chekubuda kwesimba mukati memodule yega yega, kuderedza kupisa kwenzvimbo uye kuwana hotspots.
②Optimized Optical Design
Shandisa asiri ekufungidzira optics kana homogenizing lenzi (semuenzaniso, mamicrolens arrays) kuti uvandudze kupindirana kwedanda uye kutarisisa kurongeka, nekudaro kupepeta mwenje wepombi.
③Enhanced Thermal Management
Shandisa yakakwira yekupisa conductivity zvinhu (semuenzaniso, CuW, CVD diamond) uye yunifomu yekudzora tembiricha nzira yekudzikisa chip-to-chip tembiricha kushanduka uye kuchengetedza yakagadzikana kubuda.
④Chiedza Kuwedzera Homogenization
Batanidza ma diffuser kana danda-kuumba zvinhu padivi pepombi mwenje nzira kuti uwane yakatowanda kugovera kwechiedza mukati mekuwana yepakati.
4. Kukosha Kunoshanda mu-Chaiyo-World Applications
Mune yepamusoro-yekupedzisira laser systems-zvakadai sekunyatso kugadzirwa kwemaindasitiri, kudomwa kwemauto laser, kurapwa, uye tsvakiridzo yesainzi-kugadzikana uye danda remhando yekubuda kwelaser ndiyo yakakosha. Non-uniform kuwana kugoverwa kunokonzeresa kuvimbika kwesystem uye huroyi, kunyanya mune anotevera mamiriro:
①High-energy pulsed lasers: Inodzivirira kuzara kwenzvimbo kana kuti nonlinear mhedzisiro
②Fiber laser amplifiers: Inodzvinyirira ASE (Amplified Spontaneous Emission) kuvaka
③LIDAR uye masisitimu ekutsvaga: Inovandudza kuyerwa kwechiyero uye kudzokorora
④Medical lasers: Inovimbisa chaiyo kutonga kwesimba panguva yekurapa
5. Mhedziso
Gain kugovera yunifomu inogona kunge isiri iyo inonyanya kuoneka paramende yepombi module, asi yakakosha kune yakavimbika simba repamusoro-inoshanda laser masisitimu. Sezvo zvinodiwa pamhando yelaser uye kugadzikana kuri kuramba kuchikwira, vagadziri vepombi module vanofanirwa kubata“kufanana kutonga”as a core process-inogara ichinatsa chip kusarudzwa, dhizaini dhizaini, uye nzira dzekupisa kuendesa mamwe akavimbika uye anowirirana laser masosi kune yakadzika maapplication.
Kufarira mashandisiro atinoita kuwana kufanana mumapombi edu epombi? Bata nesu nhasi kuti udzidze zvakawanda nezvemhinduro dzedu uye rutsigiro rwehunyanzvi.
