Nkọwa dị mkpirikpi:

Ndị otu Erbium na-etolite laser eriri fiber ugboro abụọ ọwa nwere ike nrụpụta kachasị ruo 1W/2W maka gravimeter gradiometer dabere na Rb oyi atom.Enwere ike ịkpọchi ọdịiche ugboro ugboro n'etiti ọwa abụọ ahụ site na usoro mgbachi ugboro/ nkeji oge.Enwere ike ịnye ọdụ ụgbọ mmiri mmepụta nke 1560/780 nm laser, nke na-enye ọkụ ọkụ dị elu maka gravimeter, quantum optics na ihe ndị ọzọ.A na-ejikọta laser mkpụrụ, amplifier na ugboro ugboro abụọ nke laser chanel 1560 nm n'ime obere akpa ikuku.Igwe ahụ dum nwere nhazi kọmpat, arụmọrụ kwụsiri ike na nke a pụrụ ịdabere na ya, ma nwee ike ịgafe ịma jijiji na ule okpomọkụ dị elu.
