Ulwazi olusisiseko lwetekhnoloji yokusika i-laser

Umgaqo wokusebenza wokusika nge-laser

Ukusika nge-laser kuxhotyiswe ngejenereyitha ye-laser ekhupha umqadi we-laser onamandla aphezulu. Umqadi we-laser uya kuthi emva koko ujoliswe yilensi kwaye wenze indawo encinci kakhulu yokukhanya kwamandla aphezulu. Ngokujolisa indawo yokukhanya kwiindawo ezifanelekileyo, izixhobo ziya kutsala amandla avela kukukhanya kwe-laser kwaye emva koko ziphele, zinyibilike, zivuthe okanye zifikelele kwindawo yokutsha. Emva koko umoya oncedisayo woxinzelelo oluphezulu (i-CO2, i-Oxygen, i-Nitrogen) uya kutshaya intsalela yenkunkuma. Intloko ye-laser iqhutywa yi-servo motor elawulwa yinkqubo kwaye ihamba ngendlela emiselweyo kwizixhobo ukuze inqumle iziqwenga zomsebenzi zeemilo ezahlukeneyo.

Iindidi zeejeneretha zelaser (imithombo yelaser)

Ukukhanya kunokwahlulwahlulwa ngokukhanya okubomvu, ukukhanya okuorenji, ukukhanya okutyheli, ukukhanya okuluhlaza njalo njalo. Kungafunxwa okanye kubonakaliswe zizinto. Ukukhanya kwelaser nako kukukhanya. Kwaye ukukhanya kwelaser okunobude obahlukeneyo bomda kuneempawu ezahlukeneyo. I-gain medium yejenereyitha yelaser eyi-medium eguqula umbane ube yi-laser igqiba ubude bomda, amandla okukhupha kunye nokusetyenziswa kwelaser. Kwaye i-gain medium inokuba yimeko yegesi, imeko yolwelo kunye nemeko eqinileyo.

1. Eyona laser iqhelekileyo yegesi yilaser yeCO2;

2. Eyona laser iqhelekileyo ye-solid state ibandakanya i-fiber laser, i-YAG laser, i-laser diode kunye ne-ruby laser;

3. I-laser yemeko yolwelo isebenzisa ezinye izinto ezilulwelo ezifana ne-organic solvent njengendlela yokusebenza ukuvelisa ukukhanya kwe-laser.

Izinto ezahlukeneyo zifunxa ukukhanya kwelaser kwiiwavelengths ezahlukeneyo. Ke ngoko, ijenereyitha yelaser kufuneka ikhethwe ngononophelo. Kwishishini leemoto, ilaser esetyenziswa kakhulu yilaser yefayibha.

Iindlela zokusebenza zomthombo we-laser

Umthombo welaser uhlala uneendlela ezintathu zokusebenza: imo eqhubekayo, imo yokuguqula kunye nemo yokubetha kwentliziyo.

Phantsi kwendlela eqhubekayo, amandla okukhupha elaser ahlala ehleli. Oku kwenza ubushushu obungena kwizinto bulingane, ngoko ke bufaneleke ekunqumleni isantya. Oku akunakuphucula kuphela ukusebenza kakuhle kodwa kukwanokwenza kube mandundu isiphumo sendawo echaphazela ubushushu.

Phantsi kwendlela yokuguqula, amandla okukhupha elaser alingana nomsebenzi wesantya sokusika. Ingagcina ubushushu obungena kwizixhobo kwinqanaba eliphantsi ngokukhawulela amandla kwindawo nganye ukuze kuthintelwe umda wokusika ongalinganiyo. Ekubeni ulawulo lwayo luyinkimbinkimbi kancinci, ukusebenza kakuhle akuphezulu kwaye kunokusetyenziswa ixesha elifutshane kuphela.

Imo yepulse inokwahlulwa ibe yimo yepulse eqhelekileyo, imo ye-super pulse kunye nemo ye-super-intense pulse. Kodwa umahluko ophambili phakathi kwabo ngumahluko wobungqongqo. Abasebenzisi banokwenza isigqibo ngokusekelwe kwiimpawu zezinto kunye nokuchaneka kwesakhiwo.

Ngamafutshane, i-laser idla ngokusebenza phantsi kwemo eqhubekayo. Kodwa ukuze ufumane umgangatho wokusika ophuculiweyo, kwiintlobo ezithile zezinto, kuyimfuneko ukulungisa isantya sokutya, njengokukhawulezisa, ukunqumla isantya kunye nokulibaziseka xa ujika. Ke ngoko, phantsi kwemo eqhubekayo, akwanelanga nje ukwehlisa amandla. Amandla e-laser kufuneka alungiswe ngokutshintsha i-pulse.

Ukusika kwe-laser yepharamitha yokuseta

Ngokweemfuno ezahlukeneyo zemveliso, kuyimfuneko ukuqhubeka ulungisa iiparameter phantsi kweemeko ezahlukeneyo zokusebenza ukuze ufumane iiparameter ezilungileyo. Ukuchaneka kwendawo eqhelekileyo yokusika nge-laser kungafikelela kwi-0.08mm kwaye ukuchaneka kwendawo ephindaphindwayo kungafikelela kwi-0.03mm. Kodwa kwimeko yokwenyani, ukunyamezelana okuncinci kufana ne-±0.05mm yokuvula kunye ne-±0.2mm kwindawo yomngxuma.

Izixhobo ezahlukeneyo kunye nobukhulu obahlukeneyo zifuna amandla ahlukeneyo okunyibilika. Ke ngoko, amandla okukhupha afunekayo e-laser ahlukile. Kwimveliso, abanini befektri kufuneka benze ulungelelwaniso phakathi kwesantya sokuvelisa kunye nomgangatho kwaye bakhethe amandla okukhupha afanelekileyo kunye nesantya sokusika. Ke ngoko, indawo yokusika inokuba namandla afanelekileyo kwaye izixhobo zinokunyibilika ngempumelelo enkulu.

Ukusebenza kakuhle kwe-laser ukuguqula umbane ube ngamandla e-laser kumalunga ne-30%-35%. Oko kuthetha ukuba xa amandla okufaka amalunga ne-4285W ~ 5000W, amandla okukhupha amalunga ne-1500W kuphela. Ukusetyenziswa kwamandla okufaka mkhulu kakhulu kunamandla okukhupha aqhelekileyo. Ngaphandle koko, ngokomthetho wokulondolozwa kwamandla, amanye amandla aguquka abe bubushushu, ngoko ke kuyimfuneko ukongeza i -water chiller yemizi-mveliso .

I-S&A ngumvelisi we-chiller othembekileyo onamava eminyaka eli-19 kwishishini le-laser. Ii-chiller zamanzi zoshishino ezivelisayo zifanelekile ukupholisa iintlobo ngeentlobo zee-laser. I-laser yefayibha, i-laser ye-CO2, i-laser ye-UV, i-laser ekhawulezayo, i-laser diode, i-laser ye-YAG, ukubala ezimbalwa. Zonke ii-chiller ze-S&A zenziwe ngezinto ezivavanyiweyo ngexesha ukuqinisekisa ukusebenza okungenazingxaki ukuze abasebenzisi baqiniseke ukuba bayazisebenzisa.
