Ndụmọdụ WISOPTIC nke teknụzụ Laser: Ozizi Mgbanwe nke oghere anya nke Gaussian Beams

N'ozuzu, ike irradiation nke laser bụ Gaussian, na n'ime usoro iji laser eme ihe, a na-ejikarị usoro anya eme ihe iji gbanwee ọkụ ọkụ ahụ.

Dị iche na nke linear tiori nke geometric optics, anya mgbanwe echiche nke Gaussian beam bụ ihe na-adịghị adị, nke nwere njikọ chiri anya na paramita nke laser beam n'onwe ya na ikwu ọnọdụ nke ngwa anya usoro.

Enwere ọtụtụ paramita iji kọwaa eriri laser Gaussian, mana mmekọrịta dị n'etiti radius ntụpọ na ọnọdụ n'úkwù ka a na-ejikarị edozi nsogbu ndị bara uru. Ya bụ, radius n'úkwù nke ihe ahụ merenụ (ω1) na anya nke usoro mgbanwe ngwa anya (z1) mara, na mgbe ahụ, gbanwee radieshon n'úkwù radius (ω2), ọnọdụ nku nku (z2) na radius ntụpọ (ω3) n'ọnọdụ ọ bụla (z) enwetara. Lekwasị anya na oghere, wee họrọ ọnọdụ ihu na azụ n'úkwù nke oghere ahụ dị ka ụgbọ elu ntụaka 1 na ụgbọ elu ntụaka 2 n'otu n'otu, dị ka egosiri na Fig. 1.
