Kugamuchirwa kuRuijie Laser

Optical fiber yefiber laser yekucheka muchina imhando yepakati-infrared bhendi laser ine fiber laser sechinhu chekushanda (kuwana svikiro).Inogona kukamurwa kuita isingawanzo pasi doped fiber laser, optical fiber nonlinear effect laser, single crystal fiber laser, fiber arc lasers, nezvimwewo.Pakati pazvo, isingawanzo pasi doped fiber lasers yakakura kwazvo, senge doped erbium fiber amplifier (EDFA) yakashandiswa zvakanyanya mu optical fiber kutaurirana masisitimu.High fiber lasers inonyanya kushandiswa muchiuto (photoelectric kutarisana, kuona laser, laser kutaurirana, nezvimwewo), laser processing (laser marking, laser robhoti, laser micromachining, nezvimwewo), zvekurapa nezvimwe minda.

Iyo fiber laser inogadzirwa neSiO2 seye matrix zvinhu zvegirazi rakasimba faibha, iri musimboti wegwara rechiedza kushandisa iyo yakazara ratidziro musimboti wechubhu, ndiko kuti, kana mwenje uchiburitswa kubva kuoptical density yepakati yepamusoro refractive. indekisi kune imwe yediki refractive index ine kona yakakura kupfuura kona yakakosha, ratidziro yakazara ichaonekwa uye chiedza chechiitiko chicharatidzwa zvachose kune optical density medium ye high refractive index.Kana mwenje uchinge waburitswa kubva kuoptical density medium (kureva kuti, refractive index yechiedza mukati mepakati yakakura) kusvika pakuonana kweiyo optical sparse medium (kureva, refractive index yechiedza idiki mukati), chiedza chese chinotaridzwa kudzoka muchimiro chepakutanga.Hapana chiedza chekupinda mukati me optical density medium inova yediki refractive index. 125μm) uye yekunze yakasimbiswa resin coating.Fiber optic propagation mode inogona kukamurwa kuita imwe-modhi (SM) faibha uye akawanda-modhi (MM) faibha.Single-modhi faibha musimboti dhayamita, yediki dhayamita yepakati (4 ~ 12μm) inogona kungoparadzira imwe modhi yechiedza uye nzira yekuparadzira idiki.Multimode faibha musimboti dhayamita iyo yakakora (dhayamita yakakura kupfuura 50μm) inogona kuparadzira nzira dzakasiyana dzechiedza nepo intermodal dispersion yakakura.Zvinoenderana nerefractive distribution rate, optic fiber inogona kukamurwa kuita nhanho index (SI) fiber uye graded index (GI) fiber.

Tora isingawanzo pasi doped fiber lasers semuenzaniso, yakashongedzwa neasingawanzo pasi pasi senge yepakati, doped fibers inomiswa pakati pemagirazi maviri achigadzira mhango inonzwika.Chiedza chepombi chiitiko kubva kuM1 kupinda mufiber uye chobva chaburitsa laser kubva kuM2.Apo chiedza chepombi chinopfuura nepakati pefiber, inotorwa neayoni asingawanzoitiki pasi mufiber uye maerekitironi anofara kusvika pakukwirira kwepamusoro kuti awane kushanduka kwevanhu kwezvikamu.Izvo zvimedu zvakachinjika zvinotamiswa kubva kune yakakwirira simba nhanho kuenda kune yepasi mamiriro muchimiro chemwaranzi kuti ibudise laser.
