Fiber laser.
Fiber lasers na-enye ụzọ dị ọnụ ahịa iji gbanwee nchapụta nke lasers semiconductor dị elu. Ọ bụ ezie na optics multiplexing wavelength nwere ike ịtụgharị lasers semiconductor na-enwu dị obere ka ọ bụrụ nke na-egbuke egbuke, nke a na-abịa na ọnụ ahịa obosara spectral na mgbagwoju anya foto.
