1535nm Pulse Mode Fiber Laser
Nkọwa Ngwaahịa
Ngwaahịa a bụ isi iyi laser eriri pulsed 1.5μm maka nchekwa anya mmadụ nke Lumispot mepụtara. Ngwaahịa a nwere ike imepụta mmepụta ike kachasị elu, yana arụmọrụ mgbanwe eletriki-optical dị elu, obere mkpọtụ mmetụta ASE na enweghị ahịrị, yana oke ọrụ okpomọkụ sara mbara. Ọ dabara adaba maka iji ya dị ka isi iyi ọkụ LiDAR.
