1. Sebenzisa ubude bogxininiso ukudayela kwindawo ethile yembono: Ubude bojoliso ngalunye bunobude obuthile.Ukuba ubude obaliweyo akulunganga, isiphumo sokukrola asiyi kufana.
2. Ibhokisi ibekwe kwindawo ezinzileyo ukwenzela ukuba i-galvanometer, isibuko sentsimi kunye netafile yokuphendula ayifani, kuba intonga kunye nemveliso iya kuba nobude obuhlukeneyo, okubangela ukuba umkhiqizo ungalingani.
3. I-Thermal lens phenomenon: Xa i-laser idlula kwi-lens optical (i-refraction, reflection), i-lens iyatshisa kwaye ibangele ukuguqulwa okuncinci.Le deformation iya kubangela ukwanda kwingqwalasela ye-laser kunye nokunciphisa ubude becala.Xa umatshini umile kwaye umgama utshintshiwe kugxininiso, emva kokuba i-laser ivuliwe kangangexesha elithile, ukuxinana kwamandla e-laser esebenza kutshintsho lwemathiriyeli ngenxa ye-thermal lensing phenomenon, ekhokelela kukungalingani okuchaphazela amanqaku. .
4. Ukuba, ngenxa yezizathu eziphathekayo, iimpawu zebhetshi yezinto eziphathekayo azihambelani, utshintsho olubangelwayo lomzimba kunye neekhemikhali luya kuba luhluke.Izinto eziphathekayo zivakalelwa kakhulu kwimpendulo ye-laser.Ngokuqhelekileyo, impembelelo yento ihlala rhoqo, kodwa izinto ezingahambelaniyo zikhokelela kwiziphene zemveliso.Isiphumo sinomkhethe ngenxa yokuba ixabiso lamandla e-laser elinokufunyanwa yimathiriyeli nganye yahlukile, nto leyo ekhokelela kukungalingani kwimveliso.
