Kuedza kweLPT-11 Serial paSemiconductor Laser

Tsananguro pfupi:

Nekuyera simba, voltage uye current ye semiconductor laser, vadzidzi vanogona kunzwisisa mashandiro e semiconductor laser pasi pe continuous output. Optical multichannel analyzer inoshandiswa kuona fluorescence emission ye semiconductor laser kana injection current iri pasi pe threshold value uye spectral line change ye laser oscillation kana current yakakura kupfuura threshold current.

Laser inowanzo kuve nezvikamu zvitatu
(1) Nzira yekushanda neLaser
Kugadzirwa kwelaser kunofanirwa kusarudza nzira yakakodzera yekushanda, inogona kuva gasi, mvura, solid kana semiconductor. Mumhando iyi yenzira, kuchinja kwehuwandu hwezvikamu kunogona kuitika, inova ndiyo mamiriro anodiwa kuti laser iwanikwe. Zviri pachena kuti kuvapo kwesimba rinoshanduka kunobatsira zvikuru pakuonekwa kwekuchinja kwenhamba. Parizvino, kune mhando dzinosvika chiuru dzemidhiya inoshanda, iyo inogona kugadzira mawavelengths akasiyana-siyana elaser kubva kuVUV kusvika kure neinfrared.
(2) Chitubu chinobva
Kuti kudzorwa kwehuwandu hwezvimedu zvionekwe munzvimbo inoshanda, zvinodikanwa kushandisa dzimwe nzira dzekumutsa maatomu kuti huwandu hwezvimedu zviwedzere munzvimbo yepamusoro. Kazhinji, kuburitswa kwegasi kunogona kushandiswa kukurudzira maatomu e dielectric nemaerekitironi ane kinetic energy, iyo inonzi electrical excitation; pulse light source inogonawo kushandiswa kuvhenekera nzvimbo inoshanda, iyo inonzi optical excitation; thermal excitation, chemical excitation, nezvimwewo. Nzira dzakasiyana dzekukurudzira dzinoonekwa sepombi kana pombi. Kuti uwane laser output nguva dzose, zvinodikanwa kupomba nguva dzose kuti huwandu hwezvimedu munzvimbo yepamusoro hurambe hwakanyanya kupfuura huri munzvimbo yakaderera.
(3) Gomba rine resonant
Nekushandisa zvinhu zvakakodzera uye sosi yekufadza, kuchinja kwenhamba yezvikamu kunogona kuonekwa, asi simba remwaranzi inosimudzirwa harina simba, saka haigone kushandiswa mukuita. Saka vanhu vanofunga kushandisa optical resonator kuti iwedzere simba. Iyo inonzi optical resonator chaizvoizvo magirazi maviri ane high reflectivity akaiswa kumeso nemeso kumativi ese elaser. Rimwe rinenge reflection yakazara, rimwe rinonyanya kuratidzwa uye rinotumirwa zvishoma, kuitira kuti laser ikwanise kuburitswa negirazi. Chiedza chinodzoserwa kumashure kune inoshanda chinoramba chichikonzera mwaranzi itsva inosimudzirwa, uye chiedza chinowedzerwa simba. Nokudaro, chiedza chinotenderera mberi nekudzoka mu resonator, zvichikonzera chain reaction, iyo inowedzerwa seavalanche, ichiburitsa laser output yakasimba kubva kune rimwe divi regirazi reflection repartial.
