Maganin laser magani ne na likitanci wanda ke amfani da haske mai haske don ƙarfafa wani tsari da ake kira photobiomodulation (PBM yana nufin photobiomodulation). A lokacin PBM, photons suna shiga cikin kyallen kuma suna hulɗa da hadaddun cytochrome c a cikin mitochondria. Wannan hulɗar tana haifar da tarin abubuwan da ke faruwa a cikin halitta wanda ke haifar da ƙaruwar metabolism na ƙwayoyin halitta, wanda zai iya rage zafi da kuma hanzarta tsarin warkarwa.
An bayyana maganin photobiomodulation a matsayin wani nau'i na maganin haske wanda ke amfani da tushen haske mara ionizing, gami da lasers, diodes masu fitar da haske, da/ko hasken broadband, a cikin hasken lantarki mai gani (400 - 700 nm) da kuma kusa da infrared (700 - 1100 nm). Tsarin da ba na zafi ba ne wanda ya ƙunshi chromophores na ciki waɗanda ke haifar da photophysical (watau, layi da mara layi) da abubuwan da suka faru na photochemical a ma'aunin halittu daban-daban.
