Malaser eMicrocavity complex kubva kumatunhu akarairwa kuenda kune asina kurongeka

Laser yakajairika ine zvinhu zvitatu zvinokosha: pombi inobva, gain medium inowedzera mwaranzi inomutswa, uye chimiro che cavity chinogadzira optical resonance. Kana saizi ye cavity yelaserYava pedyo nechikamu che micron kana submicron, yave imwe yenzvimbo dzinonyanya kutsvagurudzwa munharaunda yedzidzo: ma microcavity lasers, anogona kuwana kudyidzana kwakakosha kwechiedza nezvinhu muhuwandu hushoma. Kubatanidza ma microcavities nemasisitimu akaomarara, akadai sekuunza miganhu ye cavity isina kurongeka kana isina kurongeka, kana kuisa complex kana disordered working media muma microcavities, zvichawedzera rusununguko rwekubuda kwe laser. Hunhu hwepanyama husina kuumbwa kwema disordered cavities hunounza nzira dzakawanda dzekudzora ma laser parameters, uye hunogona kuwedzera kugona kwayo kushandiswa.

Masisitimu akasiyana-siyana ezvisina kurongekama laser emugodhi we microcavity
Mupepa rino, ma-laser e-random microcavity akapatsanurwa kubva muzvikamu zvakasiyana zvemukati kekutanga. Musiyano uyu haungoratidzi chete hunhu hwakasiyana hwerandom microcavity laser muzvikamu zvakasiyana, asiwo unotsanangura zvakanakira musiyano wehukuru hwerandom microcavity muminda yakasiyana-siyana yekutonga uye yekushandisa. Iyo three-dimensional solid-state microcavity inowanzo kuve nemode volume diki, nokudaro ichiwana kudyidzana kwakasimba kwechiedza nechinhu. Nekuda kwechimiro chayo che three-dimensional closed, light field inogona kuiswa munzvimbo yakakura muzvikamu zvitatu, kazhinji ne high quality factor (Q-factor). Hunhu uhu hunoita kuti ive yakakodzera high-precision sensing, photon storage, quantum information processing uye mamwe minda ye tekinoroji yepamusoro. Iyo open two-dimensional thin film system inzvimbo yakanaka yekuvaka planar structures dzisina kurongeka. Se two-dimensional disordered dielectric plane ine integrated gain and scattering, iyo thin film system inogona kutora chikamu mukugadzirwa kwe random laser. Iyo planar waveguide effect inoita kuti laser coupling uye collection ive nyore. Kana chiyero chegomba chaderedzwa zvakanyanya, kubatanidzwa kwemhinduro nekuwana media mugwara remafungu rimwe chete kunogona kudzvinyirira kupararira kwechiedza cheradial ukuwo kuchivandudza kupenya kwechiedza cheaxial uye kubatana kwacho. Nzira iyi yekubatanidza inozopedzisira yavandudza kushanda kwekugadzirwa nekubatanidza nelaser.

Hunhu hwekutonga hwe random microcavity lasers
Zviratidzo zvakawanda zvema laser echinyakare, zvakaita sekubatana, threshold, output direction uye polarization characteristics, ndizvo zvinonyanya kukosha pakuyera output performance yema laser. Kana tichienzanisa nema laser echinyakare ane fixed symmetric cavities, random microcavity laser inopa flexibility yakawanda mukudzora ma parameter, izvo zvinoratidzwa muzvikamu zvakasiyana-siyana zvinosanganisira time domain, spectral domain uye spatial domain, zvichiratidza kuti multi-dimensional controllability ye random microcavity laser.

Hunhu hwekushandiswa kwema lasers asina kurongeka e microcavity
Kubatana kushoma munzvimbo, kusarongeka kwemamiriro ezvinhu uye kusanzwisisa nharaunda zvinopa zvinhu zvakawanda zvakanaka pakushandisa ma stochastic microcavity lasers. Nemhinduro yekudzora maitiro uye kutonga kwegwara re random laser, sosi iyi yechiedza yakasiyana iri kushandiswa zvakanyanya mumifananidzo, kuongororwa kwezvirwere, kunzwa, kutaurirana kwemashoko nedzimwe nzvimbo.
Se laser ine hutachiona husina kurongeka pachiyero che micro ne nano, laser ine hutachiona husina kurongeka inonzwa zvakanyanya kuchinja kwezvakatipoteredza, uye hunhu hwayo hwe parametric hunogona kupindura kune zviratidzo zvakasiyana-siyana zvinotarisa nharaunda yekunze, zvakaita sekupisa, hunyoro, pH, huwandu hwemvura, refractive index, nezvimwewo, zvichigadzira puratifomu yepamusoro yekuzadzisa mashandisirwo e high-sensitivity sensitivity. Mundima yekufungidzira, yakanakirachiedza chinobvainofanira kunge iine huwandu hwakawanda hwema spectral, simba guru rinobuda mugwara uye kubatana kwakaderera kwenzvimbo kudzivirira kukanganisa kwemavara madiki. Vaongorori vakaratidza zvakanakira ma random lasers ekufungidzira kusina mavara mu perovskite, biofilm, liquid crystal scatterers uye cell tissue carriers. Mukuongorora kwechiremba, random microcavity laser inogona kutakura ruzivo rwakapararira kubva ku biological host, uye yakashandiswa zvinobudirira kuona matishu akasiyana-siyana e biological, izvo zvinoita kuti zvive nyore kuongororwa kwechiremba kusingakuvadzi.

Mune ramangwana, kuongororwa kwakarongeka kwezvimiro zve microcavity zvisina kurongeka uye nzira dzakaoma dzekugadzira laser zvichave zvakakwana. Nekufambira mberi kuri kuramba kuchiita sainzi yezvinhu uye nanotechnology, zvinotarisirwa kuti zvimiro zve microcavity zvisina kurongeka zvakanaka uye zvinoshanda zvichagadzirwa, izvo zvine mukana mukuru mukusimudzira kutsvagurudza kwekutanga uye mashandisirwo anoshanda.
