Nd: YAG — Ihe kacha mma Laser ihe siri ike
Nkọwa ngwaahịa
Nd: YAG ka bụ ihe laser steeti siri ike nwere arụmọrụ kachasị mma. Nd:YAG lasers ka a na-agbapụta n'ụzọ anya site na iji flashtube ma ọ bụ diodes laser.
Ndị a bụ otu n'ime ụdị laser a na-ahụkarị, a na-ejikwa ya maka ọtụtụ ngwa dị iche iche. Nd: YAG lasers na-ebunye ọkụ na ogologo ogologo nke 1064nm, na infrared. Nd: YAG lasers na-arụ ọrụ na ọnọdụ pulsed ma na-aga n'ihu. Pulsed Nd: YAG lasers ka a na-arụ ọrụ n'ụdị a na-akpọ Q-switching mode: A na-etinye mgba ọkụ anya n'ime oghere laser na-eche ntụgharị ọnụ ọgụgụ kachasị na ion neodymium tupu ya emepee.
Mgbe ahụ, ọkụ ebili mmiri nwere ike na-agafe n'ọgba ahụ, na-emebi usoro laser nwere obi ụtọ na ntụgharị ọnụ ọgụgụ kachasị elu. N'ụdị mgbanwe Q a, a rụpụtala ikike mmepụta nke megawatts 250 na oge pulse nke 10 ruo 25 nanoseconds.[4] Enwere ike ịgbatị mkpụrụ akụ dị elu nke ọma ugboro abụọ iji mepụta ọkụ laser na 532 nm, ma ọ bụ harmonics dị elu na 355, 266 na 213 nm.
The Nd: YAG Laser mkpanaka nke ụlọ ọrụ anyị na-emepụta nwere njirimara nke uru dị elu, ọnụ ala laser dị ala, ezigbo ọkụ ọkụ na ujo ọkụ. Ọ dabara maka ụdị ọrụ dị iche iche (na-aga n'ihu, pulse, Q-switch na mkpọchi ọnọdụ).
A na-ejikarị ya na lasers steeti siri ike nke infrared dị nso, ugboro abụọ na ngwa ngwa ugboro atọ, a na-ejikarị ya na nyocha sayensị, ọgwụgwọ ahụike, ụlọ ọrụ na mpaghara ndị ọzọ.
