Tsawon Raƙumi (raka'o'in gama gari: nm zuwa μm)

Tsawon Wave yana nuna halayen mitar raƙuman haske da laser ke fitarwa a sararin samaniya. Yanayin aikace-aikace daban-daban suna da buƙatu daban-daban don tsawon rai: A cikin sarrafa kayan aiki, ƙimar sha na kayan don takamaiman tsawon rai ya bambanta, wanda zai shafi tasirin sarrafawa. A cikin aikace-aikacen ji na nesa, akwai bambance-bambance a cikin sha da tsangwama na tsawon rai daban-daban ta hanyar yanayi. A cikin aikace-aikacen likita, sha na'urorin laser ta mutanen da ke da launuka daban-daban suma sun bambanta dangane da tsawon rai. Saboda ƙaramin wuri mai mai da hankali, na'urorin laser masu gajeriyar wavelength dana'urorin gani na Lasersuna da fa'ida wajen ƙirƙirar ƙananan siffofi masu kyau, suna samar da ƙarancin dumama na gefe. Duk da haka, idan aka kwatanta da lasers masu tsayin tsayi, yawanci suna da tsada kuma suna da saurin lalacewa.

2. Ƙarfi da kuzari (Nau'o'in gama gari: W ko J)

Ana auna ƙarfin Laser a watts (W) kuma ana amfani da shi don auna fitowar lasers masu ci gaba ko matsakaicin ƙarfin lasers masu pulsed. Ga lasers masu pulsed, kuzarin bugun guda ɗaya yana daidai gwargwado kai tsaye da matsakaicin ƙarfin kuma yana daidai gwargwado da mitar maimaitawa, tare da na'urar shine joule (J). Girman ƙarfin ko kuzari, yawan kuɗin laser yawanci yana ƙaruwa, yawan buƙatar watsa zafi yana ƙaruwa, kuma wahalar kiyaye ingantaccen ingancin haske shima yana ƙaruwa daidai gwargwado.

3. Tsawon bugun jini (Nau'ikan da aka saba amfani da su:fs zuwa ms)

Tsawon lokacin bugun laser, wanda kuma aka sani da faɗin bugun jini, gabaɗaya ana bayyana shi azaman lokacin da yake ɗauka don bugunlaserƘarfin ya tashi zuwa rabin kololuwar sa (FWHM) (Hoto na 1). Faɗin bugun lasers mai sauri yana da matuƙar gajarta, yawanci yana farawa daga picoseconds (daƙiƙa 10⁻¹²) zuwa attoseconds (daƙiƙa 10⁻¹⁸).

4. Yawan maimaitawa (Nau'o'in gama gari :Hz zuwa MHZ)

Yawan maimaitawa na alaser mai bugun jini(watau, mitar maimaita bugun jini) yana bayyana adadin bugun da ake fitarwa a kowace daƙiƙa, wato, ma'aunin tazara tsakanin bugun jini na lokaci (Hoto na 1). Kamar yadda aka ambata a baya, yawan maimaitawar yana daidai da ƙarfin bugun jini kuma yana daidai da matsakaicin ƙarfin. Kodayake yawan maimaitawar yawanci ya dogara ne akan matsakaicin ƙarfin laser, a lokuta da yawa, yawan maimaitawar na iya bambanta. Mafi girman yawan maimaitawar, mafi ƙarancin lokacin shakatawa na zafi na saman sinadarin laser da wurin da aka mayar da hankali a kai, ta haka ne kayan zai iya yin zafi da sauri.

5. Tsawon daidaito (Nau'ikan gama gari :mm zuwa cm)

Lasers suna da daidaito, wanda ke nufin akwai dangantaka mai ƙarfi tsakanin ƙimar matakin filin lantarki a lokuta ko wurare daban-daban. Wannan saboda ana samar da lasers ta hanyar fitar da hayaki mai ƙarfi, wanda ya bambanta da yawancin sauran nau'ikan tushen haske. A duk lokacin yaduwar, daidaito yana raguwa a hankali, kuma tsawon daidaituwar laser ɗin yana ƙayyade nisan da daidaiton na ɗan lokaci ke riƙe da wani nauyi.

6. Rarrabuwa

Polarization yana bayyana alkiblar filin lantarki na raƙuman haske, wanda koyaushe yana daidai da alkiblar yaɗuwa. A mafi yawan lokuta, lasers suna da polarization a layi, wanda ke nufin cewa filin lantarki da aka fitar koyaushe yana nuna alkibla ɗaya. Hasken da ba shi da polarization yana samar da filayen lantarki da ke nuna alkibla daban-daban. Matsakaicin polarization yawanci ana bayyana shi azaman rabo na ƙarfin gani na yanayin polarization guda biyu na orthogonal, kamar 100:1 ko 500:1.
