makina odulira a laser

Laser ndi mtundu wa kuwala komwe, monga momwe kumakhalira ndi ma electroluminescence ake, kumapangidwa ndi kusintha kwa atomiki (mamolekyulu kapena ma ionic) ndipo kumachitika chifukwa cha kuwala kodzidzimutsa. Ngakhale kuti laser ndi yowala, koma mwachionekere ndi yosiyana ndi kuwala wamba chifukwa chakuti laser imangodalira kuwala kodzidzimutsa kwa nthawi yochepa kwambiri poyamba, ndipo njira pambuyo pake imatsimikiziridwa kwathunthu ndi kuwala kodzidzimutsa, kotero laser ili ndi mtundu woyera kwambiri, pafupifupi palibe kusiyanitsa kwa ma divergence, makina ojambula, mphamvu yowala kwambiri. Nthawi yomweyo, laser ili ndi mgwirizano wapamwamba, mphamvu yayikulu, kutsogozedwa kwakukulu, laser imafalikira ndi chowunikira pambuyo poti laser yapangidwa ndikuyatsidwa ku zinthu zokonzedwa kudzera pagalasi losonkhanitsira, kotero kuti zinthu zokonzedwa (pamwamba) zimayikidwa mphamvu yamphamvu yotentha ndipo kutentha kumawonjezeka kwambiri, kotero kuti mfundoyo imasungunuka mwachangu kapena kusungunuka chifukwa cha kutentha kwakukulu, ndipo njira yoyendetsera mutu wa laser imagwiritsidwa ntchito kukwaniritsa cholinga chokonza.
