Isu hatizive nezve laser tekinoroji
Isu hatizive nezve laser tekinoroji, 1960 yaingova yekutanga yakabudirira laser kugadzira.Panyaya yelaser ndeye theoretical kugadzirira uye maitiro ekugadzira aidiwa nekukurumidza kumashure akabuda, akabuda, kuti awane kukurumidza kusimudzira kweasina kujairika, kwete chete kuvandudzwa kwelaser kuitira kuti sainzi yekare ye optics uye optical technologies iwane hupenyu hutsva, asi zvakare zvinotungamira mukubuda kwemusuwo mutsva weindasitiri.Laser yekucheka muchina laser inoita kuti vanhu vashandise nemazvo nzira dzepamberi uye nzira, kuwana mabhenefiti asina kumboitika uye mhedzisiro, kuitira kusimudzira kusimudzira kwemasimba anobereka.
Nekudaro, senge laser kucheka, laser welding, laser yekucheka muchina kwave kwakapararira kushandiswa kwehupenyu pakati pekugadzirwa, asiwo laser crystal, iyo laser terahertz ruzivo rwakadai, isu hatina kumbobata munyori wechinyorwa ichi tungamira munhu wese kuti atarise avo isu tisina. kujairana ne laser tekinoroji.
Laser yekucheka muchina laser crystal simba inogona kupihwa neyekunze optical mhango munzvimbo yepakati uye yenguva kuwirirana mune zvekristaro zvinhu zvakaenzana uye monochromatic laser mwenje.Kushanda zvinhu ndeye crystal laser.Laser crystal ne luminescence nzvimbo uye matrix makristasi anoumbwa nezvikamu zviviri.Mazhinji enzvimbo yemwenje-emitting nekumisikidza ion laser crystal chimiro, inoshanda ions zvishoma inotsiva cation matrix makristasi akaiswa laser makristasi.Paunomisikidza iyo ion inova chikamu chemugadziri wekristaro zvikamu, inoumba yega-activating laser crystal.
Laser yekucheka muchina laser crystal inoshandiswa zvakanyanya kune inoshanda ionic shanduko simbi ions uye trivalent isingawanzo-yepasi ion.Optical electronic transition metal ions iri muchikamu chekunze 3 d maerekitironi mumakristasi akadaro optical electronic panjodzi kune yakananga mhedzisiro yekristaro munda wakatenderedza, saka marudzi akasiyana ekristaro chimiro, maitiro ayo ekuona akasiyana zvakanyanya.Trivalent rare earth ions 4 f electrons ari kudzivirira maerekitironi 5 s uye 5 p ekunze, kuitira kuti crystal field ishaye simba rebasa rayo, asi basa recrystal field perturbation rinokonzeresa rakarambidzwa uye fluorescence line.Saka trivalent isingawanzo-yepasi ion mune spectra akasiyana ekristaro shanduko yesimbi ions sekuchinja zvakanyanya.
