RPMC Industrial picosecond laser neoMOS-70ps

Isishwankathelo seMveliso kunye neMvelaphi yobuGcisa

I-neoMOS-70ps ngummeli obalaseleyo weenkqubo ze-laser ze-industrial-grade picosecond eziphuhliswe yi-neoLASE yaseJamani, kwaye lilungu le-neoMOS ultrashort pulse laser series. Olu chungechunge lubandakanya iimodeli ezinobubanzi obahlukeneyo be-pulse, ukusuka kwi-femtosecond neoMOS 700fs ukuya kwi-picosecond neoMOS 10ps kunye ne-neoMOS 70ps, zenza isisombululo esipheleleyo se-ultrashort pulse laser. I-neoMOS-70ps yenzelwe ngokukodwa indawo eqhubekayo yokuvelisa kwimizi-mveliso, idibanisa itekhnoloji yefiber oscillator ephucukileyo enolwakhiwo oluthembekileyo lolwakhiwo lwe-amplifier, kunye nomboniso wokusebenza okumangalisayo kwibala lokuchaneka kwe-micromachining.

Ngokwembono yemithombo yobugcisa, uthotho lwe-neoMOS lumele uqokelelo lobuchwephesha lwe-neoLASE kwindawo yee-lasers eziqinileyo, kwaye ifilosofi yoyilo igxininisa ukulingana phakathi "kokuthembeka" kunye "nokugcinwa okuphantsi"1. Xa kuthelekiswa neenkqubo zelaser zakudala, i-neoMOS-70ps iyayishiya itekhnoloji yeCPA (i-chirped pulse amplification) kwaye yamkele i-MOPA (i-master oscillator power amplifier) ​​elula nesebenzayo, enganciphisi kuphela ubungakanani benkqubo, kodwa ikwaphucula kakhulu ukusebenza koguqulo lwamandla. Le ngcamango yoyilo isabela kwimfuno engxamisekileyo yoshishino lwe-miniaturization kunye nokuhlanganiswa kwezixhobo, okwenza ubukhulu bentloko ye-laser elawulwa ngokumangalisayo 330mm × 220mm × 90mm (15W version), eququzelela kakhulu ukuhlanganiswa kwenkqubo.

Olona khuphiswano lwe-neoMOS-70ps lubonakaliswe ekomeleleni kwayo kwinqanaba leshishini. Isixhobo senzelwe ukusebenza okuqhubekayo kwe-24/7, kwaye ixesha eliphakathi phakathi kokungaphumeleli (MTBF) lidlula lee lasers zenqanaba lebhubhoratri, ngenxa yoyilo olungafunekiyo lwamacandelo aphambili kunye novavanyo olungqongqo lokuziqhelanisa nokusingqongileyo7. Inkqubo ye-laser ithatha i-architecture ye-modular, ngokukodwa iquka iindawo ezintlanu: umthombo wembewu (i-fiber oscillator), i-preamplifier, i-amplifier ephambili, i-harmonic generator (ukhetho) kunye neyunithi yokulawula. Phakathi kwabo, umthombo wembewu usekelwe kwi-laser diode ethembekileyo yokumpompa ukuvelisa i-picosecond pulses yokuqala; Inqanaba le-amplifier lisebenzisa itekhnoloji yokukhulisa i-slid-state ukuqinisekisa ukuthembeka kweempawu ze-pulse ngexesha lokunyusa amandla.

Ngokombono wokubekwa kwemarike, i-neoMOS-70ps ijolise ikakhulu kwintsimi yokulungiswa kwezinto ezichanekileyo, kubandakanywa kodwa kungaphelelanga kwimveliso ye-photovoltaic kunye nemveliso ye-elektroniki, ukusetyenzwa kweglasi, kunye nokhuseleko kunye nezicelo zokumakisha zokuhombisa. Kule mimandla, i-70ps ububanzi be-pulse inikezela ngokufanelekileyo ulawulo lwendawo echaphazelekayo kubushushu ngelixa uphepha ubunzima kunye neendleko ze-ultrashort pulses (ezifana nee-laser ze-femtosecond). I-laser isekela uhlengahlengiso lokuphindaphinda izinga lokuphindaphinda (ukusuka kwi-single ukuya kwi-80MHz) kunye nolawulo lwamandla e-pulse (ukuya kuthi ga kwi-250μJ), enokuziqhelanisa neemfuno ezahlukeneyo zokucubungula.

Iiparamitha zobugcisa kunye neempawu zokusebenza

I-neoMOS-70ps i-picosecond laser inomsebenzi ogqwesileyo kwiiparamitha ezininzi zobugcisa ngenxa yoyilo lobunjineli obuphucukileyo, ihlangabezana ngokupheleleyo neemfuno zokuchaneka kweshishini. Ukuqonda okunzulu kwezi zalathisi zobugcisa kubalulekile ekukhetheni izixhobo, uphuhliso lwenkqubo kunye nokudibanisa inkqubo. Eli candelo liza kuhlalutya iiparitha eziphambili ze-laser kunye nentsingiselo yobugcisa emva kwabo ngokweenkcukacha ukunceda abasebenzisi baqonde ngokupheleleyo iimpawu zokusebenza kwezixhobo.

Iimpawu zemveliso ezisisiseko

Ubude obusembindini be-neoMOS-70ps yi-1064nm, eyeye-infrared spectrum range. Olu bude bamaza buneempawu ezifanelekileyo zokufunxa kwiintlobo zezixhobo zoshishino, kwaye zinokuguqulwa ngokufanelekileyo zibe ukukhanya okuluhlaza (532nm) okanye ukukhanya kwe-ultraviolet (355nm / 266nm) ngokusebenzisa iikristale ezingaqhelekanga ukuhlangabezana neemfuno ezikhethekileyo zesicelo24. I-laser inika amandla okuphuma okuphakathi kwe-15W, okuyinqanaba lamandla aphakathi ukuya phezulu phakathi kwe-lasecond lasers kwaye yanele kwimisebenzi emininzi ye-micromachining. I-pulse yayo enye yamandla inokufikelela kwi-250μJ, inika isiqinisekiso samandla esaneleyo sokulungiswa kwezinto eziphezulu.

Ububanzi be-pulse sisiseko samagama kunye ne-core feature ye-neoMOS-70ps, elawulwa ngokuchanekileyo kwi-70 picoseconds (70,000 femtoseconds)4. Olu luhlu lobubanzi be-pulse ngobuchule bulungelelanisa ukuchaneka kokuchaneka kunye nokuntsonkotha kwenkqubo - xa kuthelekiswa ne-nanosecond lasers, indawo echaphazeleke bubushushu iyancipha kakhulu, kwaye umngcipheko womonakalo obangelwa ngamandla aphezulu kakhulu e-femtosecond lasers uyaphetshwa. I-laser ixhasa uluhlu olubanzi lokuphindaphinda uhlengahlengiso ukusuka kwi-80MHz enye, kwaye abasebenzisi banokukhetha ngokuguquguqukayo ngokuhambelana nokusebenza kakuhle kunye neemfuno zokuchaneka2. Kuyafaneleka ukuba uqaphele ukuba isixhobo sinokuxhotyiswa nge "Burst mode" (imowudi ye-pulse train), enokufikelela kwimveliso yolandelelwano lwe-pulse eyinkimbinkimbi ngaphandle kokuvuselela kwangaphandle ukuhlangabezana neemfuno ezikhethekileyo zokucwangcisa izinto.
