Haɓakar Laser tana nufin haɓakar wasu adadi na Laser a kan lokaci, kamar ƙarfin gani da riba.

Halin motsin laser yana ƙaddara ta hanyar hulɗar tsakanin filin gani a cikin rami da matsakaicin riba. Gabaɗaya magana, ƙarfin Laser zai bambanta tare da bambanci tsakanin riba da rami mai resonant, kuma ƙimar canjin riba ana ƙaddara ta hanyar aiwatar da isar da iskar da iska da iskar da ba ta daɗe ba (ana iya ƙaddara ta sakamakon quenching da tsarin canja wurin makamashi).

Ana amfani da wasu ƙayyadaddun ƙima. Misali, ribar Laser ba ta da yawa. A cikin Laser haske mai ci gaba, dangantakar dake tsakanin wutar lantarki P da riba coefficient g a cikin rami ya gamsar da ma'auni mai ban sha'awa mai zuwa:

Ina T_R shine lokacin da ake buƙata don tafiya guda ɗaya a cikin rami, l shine hasara mai yawa, g_ss shine ƙaramin sigina (a wani ƙarfin famfo da aka ba shi), τ_g shine lokacin hutun samun riba (yawanci yana kusa da babban ƙarfin halin rayuwa), kuma E_sat shine tya cikakken sha makamashi na riba matsakaici.

A cikin ci gaba da laser igiyar igiyar ruwa, mafi yawan abubuwan da suka fi damuwa shine yanayin sauyawa na laser (yawanci ciki har da samuwar ƙarfin fitarwa) da yanayin aiki lokacin da akwai damuwa a cikin tsarin aiki (yawanci oscillation na shakatawa). A wannan yanayin, nau'ikan laser daban-daban suna da halaye daban-daban.

Misali, Laser insulator na doped yana da saurin yaduwa da shakatawa, amma diodes laser ba. A cikin laser Q-switched, yanayin motsi yana da matukar mahimmanci, inda makamashin da aka adana a matsakaicin riba zai canza sosai lokacin da bugun bugun jini ya fito. Q-switched fiber Laser yawanci suna da babban riba sosai, kuma akwai wasu sauran abubuwan mamaki. Yawancin lokaci yana haifar da bugun jini don samun wasu sassa a cikin yankin lokaci, wanda zai iya ba za a yi bayanin ta lissafin da ke sama ba.

Hakanan za'a iya amfani da ma'auni makamancin haka don maƙallan laser masu kulle-kulle; sannan lissafin farko yana buƙatar ƙara ƙarin lokaci don bayyana asarar saturable absorber. Sakamakon wannan sakamako shine cewa an rage raguwar oscillation na shakatawa. The shakatawa oscillation tsari ba ya ko da attenuate, don haka tsayayye-jihar bayani zama ba barga, kuma Laser yana da.wasu rashin zaman lafiya na Q-switched mode-locking ko wasu nau'ikan Q-switching.
