Rofin Industrial Solid State ukulungiswa Laser

I-Rofin's (ngoku i-Coherent's) ye-SLS i-slid-state lasers zisebenzisa iteknoloji ye-diode-pumped solid-state laser (DPSSL) kwaye isetyenziswa ngokubanzi kumashishini okucubungula (okufana nokumakisha, ukusika, ukuwelda) kunye nophando lwezenzululwazi. Olu ngcelele lweelaser luyaziwa ngozinzo lwalo oluphezulu, ubomi obude kunye nomgangatho ogqwesileyo we-beam (M²), kodwa zinokusilela emva kokusetyenziswa kwexesha elide, okuchaphazela ukusebenza.

Eli nqaku liza kwazisa isakhiwo, iimpazamo eziqhelekileyo, iingcamango zokugcina, ukugcinwa kwansuku zonke kunye nemilinganiselo yokukhusela yochungechunge lwe-SLS ngokubanzi ukunceda abasebenzisi ukwandisa ubomi bezixhobo kunye nokunciphisa ixesha lokuphumla.

2. SLS series laser ukubunjwa kwesakhiwo

Ii-laser zothotho lwe-SLS zenziwa ikakhulu ezi modyuli zingundoqo zilandelayo:

1. Intloko yeLaser

2. Imodyuli yempompo yeDiode

I-Laser diode array (LDA): Ibonelela nge-808nm impompo yokukhanya, efuna ulawulo lobushushu be-TEC ukugcina uzinzo.

Inkqubo yokulawula ubushushu (TEC): Iqinisekisa ukuba i-diode isebenza kwiqondo lokushisa eliphezulu (ngokuqhelekileyo i-20-25 ° C).

3. Inkqubo yokupholisa

Ukupholisa amanzi (i-Chiller): Iimodeli zamandla aphezulu (ezifana ne-SLS 500+) zifuna i-chiller yangaphandle ukuqinisekisa ukuba ukushisa kwentloko ye-laser kuzinzile.

Ukupholisa komoya (Ukupholisa komoya): Iimodeli zamandla aphantsi zinokusebenzisa ukupholisa umoya ngenkani.

4. Inkqubo ye-Optical (Ukuhanjiswa kweBeam)

I-Beam expander (I-Beam Expander): Lungisa i-diameter ye-beam.

Izibuko (Izibuko ze-HR / OC): Izibuko eziphezulu ezibonisa (HR) kunye nezibuko eziphumayo zokudibanisa (OC).

I-Optical isolator (i-Optical Isolator): Ikhusela ukukhanya okubuya ekonakaliseni i-laser.

5. Ulawulo kunye nokunikezelwa kwamandla

Unikezelo lwamandla okuqhuba: Ukubonelela ngokuzinzile kwangoku kunye nesignali yokumodareyitha.

Iphaneli yokulawula / isoftware: Lungisa iiparameters ezinje ngamandla, frequency, pulse wide, etc.
