Kugwiritsa ntchito Neodymium Ion Concentration Gradient YAG Crystal mu End-Pumped Laser Technology

Kukula mwachangu kwaukadaulo wa laser sikungasiyanitsidwe ndikusintha kwakukulu kwa ma semiconductor lasers, zida zopangira ma kristalo ndi zida. Pakadali pano, gawo laukadaulo wa semiconductor ndi solid-state laser technology ukukula. Pofuna kumvetsetsa bwino momwe kafukufuku wasayansi akugwirira ntchito komanso zofunikira zachitetezo cha dziko lachitetezo champhamvu kwambiri komanso ukadaulo wa laser wokhazikika, komanso kulimbikitsa kusinthana kwamaphunziro kumtunda ndi kumunsi kwaukadaulo wa laser, Chinese Society of Optical Engineering igwira. "Advanced Semiconductor, Solid-State Laser Technology and Application Exchange Conference" mu 2024 kuti agwirizane mozama pa mfundo zakuthupi, matekinoloje ofunikira, kupita patsogolo kwa ntchito, ndi chiyembekezo chamtsogolo chokhudzana ndi ma semiconductors ndi ma lasers olimba.

Pamsonkhanowu, wapampando wa kampani yathu, Zhang Jianjun, adanenanso za kugwiritsa ntchitoneodymium ion ndendegradientkristalo YAGmu teknoloji ya laser pampu yotsiriza.Ma lasers olimba-boma nthawi zambiri amapopedwa, ndipo pali mitundu iwiri ikuluikulu ya njira zopopera: pampu ya nyali ndi mpope wa diode. Ma lasers a Diode-pumped solid-state (DPSSL) ali ndi ubwino wochita bwino kwambiri, mtengo wapamwamba wa mtengo, kukhazikika kwabwino, kapangidwe kake, komanso moyo wautali. Kupopa kwa diode kumagwiritsidwa ntchito mu ma lasers a Nd:YAG m'njira ziwiri zopopera: kupopera m'mbali (kotchedwa kupopera m'mbali) ndi kupopera komaliza (kotchedwa kupopera komaliza).

Poyerekeza ndi kupopera kwa nyali ndi kupopera kwa mbali ya semiconductor, kupopera komaliza kwa semiconductor ndikosavuta kukwaniritsa mawonekedwe ofananira pakati pa kupopera kuwala ndi kuwala kwa oscillating mu patsekeke ya laser. Kuphatikiza apo, kuyang'ana mtengo wapampu kukula pang'ono pang'ono kuposa ndodo ya laser kumatha kuchepetsa kuchuluka kwamitundu yomwe ili pabowo ndikuwongolera bwino mtengowo. Panthawi imodzimodziyo, ili ndi ubwino wa compact structure, low laser threshold, komanso high performance. Kafukufuku wasonyeza kuti kupopa komaliza ndi njira yabwino kwambiri yopopa.
