Olee otú ịhọrọ n'etiti na-aga n'ihu na pulsed eriri lasers?

Fiber lasers na-eme ka ọnụ ọgụgụ na-abawanye ụba nke lasers ụlọ ọrụ kwa afọ n'ihi nhazi ha dị mfe, ọnụ ala dị ọnụ ala, arụmọrụ ntụgharị electro-optical dị elu, yana ezigbo mmepụta mmepụta. Dabere na ọnụ ọgụgụ, fiber lasers ruru 52.7% nke ahịa laser ụlọ ọrụ na 2020.

Dabere na njirimara nke nrụpụta mmepụta, fiber lasers nwere ike kewaa ụzọ abụọ:laser na-aga n'ihunapulse laser. Gịnị bụ teknuzu iche n'etiti abụọ, na ihe ngwa ndapụta bụ nke ọ bụla dabara? Ndị na-esonụ bụ ntụle dị mfe nke ngwa n'ozuzu ọnọdụ.

Dị ka aha ahụ na-egosi, mmepụta laser site na laser fiber laser na-aga n'ihu na-aga n'ihu, a na-echekwa ike na ọkwa dị elu. Ike a bụ ike nke laser.The uru nke na-aga n'ihu eriri lasers bụ ogologo oge kwụsiri ike ọrụ.

Laser nke pulse laser bụ "na-adịte aka". N'ezie, oge nkwụsịtụ a na-adịkarị mkpụmkpụ, a na-atụkarị ya na milliseconds, microseconds, ma ọ bụ ọbụna nanoseconds na picoseconds. E jiri ya tụnyere laser na-aga n'ihu, ike nke laser pulse na-agbanwe mgbe niile, ya mere enwere echiche nke "crest" na "trough".

Site pulse modulation, na pulsed laser nwere ike hapụ ngwa ngwa na iru kacha ike na ọnụ ọgụgụ kasị elu, ma n'ihi ịdị adị nke trough, nkezi ike dịtụ ala.Ọ bụ echiche na ọ bụrụ na nkezi ike bụ otu ihe ahụ, ike elu nke pulse laser nwere ike ịdị ukwuu karịa nke laser na-aga n'ihu, na-enweta njupụta ume ka ukwuu karịa laser na-aga n'ihu, nke a na-egosipụta na ikike ntinye ntinye dị ukwuu na. nhazi ígwè. N'otu oge ahụ, ọ dịkwa mma maka ihe ndị na-ekpo ọkụ na-ekpo ọkụ nke na-enweghị ike ịnagide nnukwu okpomọkụ na-adịgide adịgide, yana ụfọdụ ihe na-atụgharị uche.

Site na njirimara ike mmepụta nke abụọ, anyị nwere ike nyochaa ọdịiche ngwa.

CW fiber lasers dị mma maka:

1. Nhazi ngwá ọrụ buru ibu, dị ka ụgbọ ala na ụgbọ mmiri, ịkpụ na nhazi nke nnukwu efere ígwè, na oge nhazi ndị ọzọ na-adịghị emetụta mmetụta okpomọkụ mana ọ na-enwe mmetụta karịa ọnụ ahịa.

2. A na-eji ya na ịwa ahụ na coagulation na ngalaba ahụike, dị ka hemostasis mgbe ịwachara ahụ, wdg.

3. A na-ejikarị ya na usoro nkwurịta okwu fiber optic maka nnyefe mgbaàmà na mmụba, na nkwụsi ike dị elu na ụda olu dị ala.

4. A na-eji ngwa ndị dị ka nyocha spectral, nyocha physics atomic na lidar n'ọhịa nyocha sayensị, na-enye ike dị elu na mmepụta laser dị elu.

Laser fiber pulsed na-adabarakarị maka:

1. Nhazi nkenke nke ihe ndị na-enweghị ike iguzogide mmetụta okpomọkụ siri ike ma ọ bụ ihe na-akụjisị, dị ka nhazi nke ibe eletrọnịkị, iko seramiiki, na akụkụ ahụike ahụike.

2. Ihe nwere ihe ngosi dị elu ma nwee ike imebi isi laser n'onwe ya n'ihi ntụgharị uche. Dịka ọmụmaatụ, nhazi nke ọla kọpa na aluminom

3. Ngwọta elu ma ọ bụ ihicha nke mpụta nke ihe ndị mebiri emebi ngwa ngwa

4. Nhazi ọnọdụ nke chọrọ obere oge dị elu ike na ntinye miri emi, dị ka ịcha efere efere, ihe nkedo ígwè, wdg.

5. Ọnọdụ ebe ọ dị mkpa ka a na-eji pulses mee ihe dị ka njirimara mgbaàmà. Dị ka nkwukọrịta eriri anya na ihe mmetụta eriri anya, wdg.

6. A na-eji ya na ubi biomedical maka ịwa ahụ anya, ọgwụgwọ anụ ahụ na ịkpụ anụ ahụ, wdg, na-eji ogo beam dị elu na arụmọrụ modulation.

7. Na 3D obibi akwụkwọ, metal akụkụ na-emepụta na elu nkenke na mgbagwoju owuwu nwere ike nweta

8. Ngwá agha laser dị elu, wdg.

E nwere ụfọdụ iche n'etiti pulsed fiber lasers na-aga n'ihu eriri lasers n'usoro nke ụkpụrụ, teknuzu e ji mara na ngwa, na onye ọ bụla dabara maka dị iche iche oge. Laser fiber pulsed dabara adaba maka ngwa chọrọ ike kachasị elu na arụmọrụ modulation, dị ka nhazi ihe na ọgwụ bio, ebe lasers fiber na-aga n'ihu dabara adaba maka ngwa chọrọ nkwụsi ike dị elu na ịdị mma dị elu, dị ka nkwukọrịta na nyocha sayensị. Ịhọrọ ụdị laser fiber ziri ezi dabere na mkpa dị iche iche ga-enyere aka melite arụmọrụ na ngwa ngwa.
