A na-eji KD*P maka okpukpu abụọ, Tripling na Quadrupling nke Nd: YAG Laser
Nkọwa ngwaahịa
Ihe NLO azụmahịa kacha ewu ewu bụ potassium dihydrogen phosphate (KDP), nke nwere ọnụọgụ NLO dị ntakịrị mana nnyefe UV siri ike, ọnụ ụzọ mmebi dị elu, yana nnukwu birefringence. A na-ejikarị ya amụba laser Nd:YAG site na abụọ, atọ, ma ọ bụ anọ (na okpomọkụ mgbe niile). A na-ejikwa KDP na-arụ ọrụ na EO modulators, Q-switches, na ngwaọrụ ndị ọzọ n'ihi ịdị elu ya na-ahụ anya na ọnụ ọgụgụ EO dị elu.
Maka ngwa ndị a kpọtụrụ aha, azụmahịa anyị na-enye nnukwu kristal KDP dị elu n'ọtụtụ nha, yana nhọrọ kristal ahaziri, imewe na ọrụ nhazi.
A na-arụ ọrụ KDP usoro Pockels sel mgbe mgbe na sistemụ laser nwere nnukwu dayameta, ike dị elu na obere obosara n'ihi njiri elu anụ ahụ na anya ha. Otu n'ime ndị kasị mma EO Q-switch, ha na- tinye n'ọrụ na OEM laser usoro, ọgwụ na ịchọ mma lasers, vasatail R&D laser nyiwe, na agha na aerospace laser usoro.
Isi atụmatụ & Ngwa ahụkarị
● Ọnụ ụzọ mmebi anya dị elu na nnukwu birefringence
● Ezigbo nnyefe UV
● Electro-optical modulator na Q switches
● Ọgbọ nke abụọ, nke atọ na nke anọ, na-abawanye ugboro abụọ nke Nd: YAG laser
● Ihe ngbanwe ugboro laser dị elu
