LPT-11 Serial Ongororo paSemiconductor Laser

Tsananguro

Nekuyera iro simba, magetsi uye yazvino ye semiconductor laser, vadzidzi vanogona kunzwisisa mashandiro ehunhu ye semiconductor laser pasi pechienderera chinobuda. Optical multichannel analyzer inoshandiswa kucherechedza fluorescence emission ye semiconductor laser kana jekiseni razvino riri pasi pechikumbaridzo kukosha uye iyo spectral mutsara shanduko ye laser oscillation kana iyo yazvino iri hombe kupfuura iyo chikumbaridzo chazvino.

Laser kazhinji ine zvikamu zvitatu
(1) Laser inoshanda svikiro
Chizvarwa chemalaser chinofanira kusarudza yakakodzera inoshanda svikiro, inogona kuva gasi, mvura, yakasimba kana semiconductor. Mune iri mhando yepakati, iko kupinduka kwehuwandu hwezvimedu kunogona kuzadzikiswa, inova iyo inodikanwa mamiriro ekuti uwane laser. Zviripachena, kuvapo kwesimba remagetsi rinoshanda kunobatsira kwazvo pakuzadziswa kwenhamba inversion. Parizvino, pane angangoita 1000 marudzi enhau anoshanda, ayo anogona kuburitsa akasiyana siyana emawalvellengths kubva kuVUV kusvika kune infrared.
(2) Inokurudzira sosi
Kuti uite kutendeuka kwenhamba yezvimedu zvioneke mune yekushandira svikiro, zvinofanirwa kushandisa dzimwe nzira kufadza iyo atomiki system kuwedzera huwandu hwezvimedu mudenga repamusoro. Kazhinji, kubudiswa kwegesi kunogona kushandiswa kufadza maatomu e dielectric nemaelektroni ane simba reinetic, iro rinodaidzwa kuti kufadza kwemagetsi; kupomba mwenje sosi inogona zvakare kushandiswa kujekesa mashandiro epakati, ayo anonzi Optical excitation; kupisa kwekutsvaira, kunakidzwa kwemakemikari, nezvimwe. Nzira dzakasiyana dzekunyaradza dzinoonekwa sepombi kana pombi. Kuti uwane iyo laser inoburitsa ichienderera, zvinofanirwa kupomba uchienderera mberi kuti uchengetedze huwandu hwezvimedu mudenga repamusoro kupfuura izvo zviri muzasi chikamu.
(3) Resonant mhango
Iine yakakodzera yekushanda zvinhu uye yekunyepedzera sosi, iyo inversion ye PARTICIPLE nhamba inogona kuzadzikiswa, asi kusimba kweinosimudzira mwaranzi kwakanyanya kusimba, saka haigone kuiswa mukuita. Saka vanhu vanofunga kushandisa optical resonator kukwidziridza. Iyo inonzi Optical resonator inonyatso kuve magirazi maviri ane yakakwira reflectivity yakaiswa kumeso kumeso kumacheto maviri eiyo laser. Imwe ingangoita fungidziro izere, imwe yacho inonyanya kuratidzwa uye zvishoma inopfuudzwa, kuitira kuti iyo laser igone kuburitswa kuburikidza negirazi. Chiedza chakaratidzira kumashure kune chinoshanda svikiro chinoramba chichikonzera nyowani yakasimudzira mwaranzi, uye mwenje unowedzerwa. Naizvozvo, mwenje unofamba uchidzoka neshure mu resonator, zvichikonzera kuitisa ngetani, iyo inowedzeredzwa kunge avalanche, ichiburitsa yakasimba laser kuburitsa kubva kune mumwe mugumo wedivi rekuratidzira girazi.
