Li-laser tsa pulsed fiber hangata li loketse:
1. Ts'ebetso e nepahetseng ea thepa e ke keng ea mamella litlamorao tse matla tsa mocheso kapa lisebelisoa tse robehang, joalo ka ho sebetsa ha lichipisi tsa elektroniki, likhalase tsa ceramic le likarolo tsa bophelo bo botle.
2. Thepa e na le reflectivity e phahameng 'me e ka senya hlooho ea laser habonolo ka boeona ka lebaka la ho nahanisisa. Ka mohlala, ho sebetsana le lisebelisoa tsa koporo le aluminium
3. Phekolo ea holim'a metsi kapa ho hloekisa bokantle ba li-substrates tse senyehang habonolo
4. Maemo a ho sebetsana le maemo a hlokang matla a phahameng a nako e khutšoanyane le ho kenella ka botebo, joalo ka ho itšeha poleiti e teteaneng, ho cheka lisebelisoa tsa tšepe, joalo-joalo.
