TheLaser zangoyana wakiltar tsayin igiyoyin lantarki na lantarki da Laser ke ɗauka. Idan aka kwatanta da sauran nau'ikan haske, muhimmin fasalinLasershi ne monochromatic, wanda ke nufin cewa tsayinsa yana da tsafta sosai kuma yana da mitar ƙayyadaddun ƙayyadaddun mitoci guda ɗaya kawai.

Bambance-bambance tsakanin raƙuman ruwa na Laser daban-daban:

Tsayin jan Laser gabaɗaya yana tsakanin 630nm-680nm, kuma hasken da ke fitowa ja ne, kuma shi ne Laser da aka fi sani da shi (wanda aka fi amfani da shi a fannin hasken ciyar da likitanci, da sauransu);

Tsawon tsayin laser kore shine gabaɗaya kusan 532nm, (wanda aka fi amfani dashi a fagen kewayon Laser, da sauransu);

Blue Laser zangon shine gabaɗaya tsakanin 400nm-500nm (wanda aka fi amfani dashi don tiyatar laser);

Uv Laser tsakanin 350nm-400nm (wanda aka fi amfani dashi a biomedicine);

Laser infrared shine mafi na musamman, bisa ga kewayon tsayin tsayi da filin aikace-aikacen, tsayin laser infrared gabaɗaya yana cikin kewayon 700nm-1mm. Ƙungiyar infrared za a iya ƙara zuwa kashi uku: kusa da infrared (NIR), tsakiyar infrared (MIR) da kuma infrared mai nisa (FIR). Matsakaicin raƙuman raƙuman infrared na kusa yana kusan 750nm-1400nm, wanda aka yi amfani da shi sosai a cikin sadarwar fiber na gani, hoto na biomedical da kayan hangen nesa na dare.

2. Ƙarfi da makamashi (raka'a: W ko J)

Ƙarfin Laserana amfani da shi don kwatanta fitowar wutar lantarki ta Laser mai ci gaba da igiyar ruwa (CW) ko matsakaicin ƙarfin Laser mai bugun jini. Bugu da kari, pulsed Laser suna halin da gaskiyar cewa bugun jini makamashi daidai da matsakaicin iko da inversely gwargwado zuwa maimaita kudi na bugun jini, da kuma Laser da mafi girma iko da makamashi yawanci samar da karin sharar gida zafi.

Yawancin fitilun Laser suna da bayanin martabar katako na Gaussian, don haka rashin haske da jujjuyawar duka biyun sun fi girma akan kullin gani na Laser kuma suna raguwa yayin da karkacewa daga axis na gani yana ƙaruwa. Sauran lasers suna da bayanan bayanan katako masu lebur waɗanda, ba kamar na Gaussian ba, suna da bayanan haske akai-akai a cikin ɓangaren giciye na katako na Laser da saurin raguwar ƙarfi. Saboda haka, lebur-top Laser ba su da kololuwar haske. Ƙarfin Ƙarfin Ƙarfin Gaussian ya ninka na katako mai ɗaki tare da matsakaicin matsakaicin ƙarfi.

3. Tsawon bugun jini (naúrar: fs zuwa ms)

Tsawon bugun bugun laser (watau faɗin bugun jini) shine lokacin da ake ɗauka don laser ya kai rabin matsakaicin ƙarfin gani (FWHM).

 

4. Yawan maimaitawa (naúrar: Hz zuwa MHz)

Yawan maimaitawa na apulsed Laser(watau yawan maimaita bugun bugun jini) yana bayyana adadin bugun jini da ake fitarwa a cikin dakika daya, wato, ma'auni na tazarar bugun bugun jini. Matsakaicin maimaitawa ya yi daidai da ƙarfin bugun jini kuma ya yi daidai da matsakaicin ƙarfin. Kodayake yawan maimaitawa yawanci ya dogara ne akan matsakaicin samun laser, a yawancin lokuta, ana iya canza ƙimar maimaitawa. Matsakaicin yawan maimaitawa yana haifar da ɗan gajeren lokacin shakatawa na thermal don saman da mayar da hankali na ƙarshe na nau'in gani na Laser, wanda hakan ke haifar da saurin dumama kayan.

5. Bambance-bambance (naka'a ta al'ada: mrad)

Ko da yake a gabaɗaya ana tunanin firam ɗin Laser a matsayin haɗuwa, koyaushe suna ɗauke da ɗan ƙayyadaddun bambance-bambance, wanda ke bayyana gwargwadon yadda katakon ya bambanta akan ƙarin nisa daga kugu na katako na Laser saboda rarrabuwa. A cikin aikace-aikacen da ke da nisan aiki mai nisa, kamar tsarin liDAR, inda abubuwa na iya zama ɗaruruwan mita nesa da tsarin laser, rarrabuwa ya zama matsala mai mahimmanci.

6. Girman tabo (naúrar: μm)

Girman tabo na katakon Laser da aka mayar da hankali yana kwatanta diamita na katako a wurin mai da hankali na tsarin ruwan tabarau. A yawancin aikace-aikace, kamar sarrafa kayan aiki da aikin tiyata na likita, makasudin shine a rage girman tabo. Wannan yana ƙara girman ƙarfin ƙarfi kuma yana ba da damar ƙirƙirar siffofi na musamman masu kyau. Ana amfani da ruwan tabarau na aspherical sau da yawa maimakon ruwan tabarau mai siffar zobe na al'ada don rage ɓarna mai faɗi da kuma samar da ƙarami mai girman tabo.

7. Nisan aiki (naúrar: μm zuwa m)

Yawan nisa na tsarin laser ana bayyana shi azaman nisa ta zahiri daga ɓangaren gani na ƙarshe (yawanci ruwan tabarau mai mai da hankali) zuwa abu ko saman da Laser ke mayar da hankali a kai. Wasu aikace-aikace, kamar lasers na likita, yawanci suna neman rage nisan aiki, yayin da wasu, kamar ji na nesa, galibi suna nufin haɓaka nisan aikinsu.
