I-KD*P Isetshenziselwa Ukuphindaphinda, Ukuphindaphinda Kathathu Nokuphinda Kane Kwe-Nd:YAG Laser
Incazelo Yomkhiqizo
Impahla edume kakhulu yokuthengisa ye-NLO i-potassium dihydrogen phosphate (KDP), enama-coefficient e-NLO aphansi kodwa ukudluliselwa kwe-UV okuqinile, umkhawulo womonakalo omkhulu, kanye ne-birefringence ephezulu. Ivamise ukusetshenziselwa ukuphindaphinda i-laser ye-Nd:YAG ngamabili, amathathu, noma amane (emazingeni okushisa angashintshi). I-KDP iphinde isetshenziswe ngokujwayelekile kumamojula we-EO, ama-Q-switches, namanye amadivayisi ngenxa ye-homogeneity yayo ephezulu yokubona kanye nama-coefficient e-EO aphezulu.
Kulezi zinhlelo zokusebenza ezishiwo ngenhla, ibhizinisi lethu lihlinzeka ngosizo lwenqwaba yamakristalu e-KDP ekhwalithi ephezulu ngebanga losayizi, kanye nokukhetha kwekristalu okulungiselelwe, ukuklama, kanye nezinsizakalo zokucubungula.
Amaseli e-KDP ochungechunge lwe-Pockels asetshenziswa kaningi ezinhlelweni ze-laser ezinobubanzi obukhulu, amandla aphezulu, nobubanzi be-pulse encane ngenxa yezici zabo eziphakeme zomzimba nezokubona. Enye yamaswishi e-EO Q angcono kakhulu, asetshenziswa ezinhlelweni ze-laser ye-OEM, amalaser ezokwelapha nezimonyo, amapulatifomu e-laser e-R&D ahlukahlukene, kanye nezinhlelo ze-laser yezempi neye-aerospace.
Izici Eziyinhloko Nezinhlelo Zokusebenza Ezivamile
● Umkhawulo womonakalo obonakalayo ophezulu kanye ne-birefringence ephezulu
● Ukudluliswa okuhle kwe-UV
● Imoduli ye-electro-optical kanye namaswishi e-Q
● Isizukulwane sesibili, sesithathu, nesesine se-harmonic, ukuphindaphinda kabili kwelaser ye-Nd:YAG
● Impahla yokuguqula imvamisa ye-laser yamandla aphezulu
